| conrmahr | yes it's UEFI | 00:02 |
|---|---|---|
| conrmahr | there's even a UEFI guide that you can run | 00:02 |
| conrmahr | my UEFI version is H97M Pro4 P2.00 | 00:04 |
| conrmahr | by ASRock | 00:04 |
| JanC | I think meant GPT instead of UEFI | 00:07 |
| JanC | I think bekks meant GPT instead of UEFI | 00:08 |
| sarnold | conrmahr: normally "raid array" means "two or more disks" | 00:08 |
| conrmahr | yes | 00:09 |
| conrmahr | i had 2 WD 4TB HDDs Raided together | 00:10 |
| conrmahr | on a Synology NAS | 00:10 |
| conrmahr | Can I delete one of them on Ubuntu Server so I can transfer the backup HDD from the NAS to the Ubuntu Server HDD over the network? | 00:11 |
| nacc | conrmahr: your question is very confusing | 00:12 |
| nacc | coreycb: you had a 2-disk RAID array | 00:12 |
| nacc | coreycb: sorry | 00:12 |
| nacc | conrmahr: you had a 2-disk RAID array | 00:12 |
| conrmahr | yes | 00:12 |
| nacc | conrmahr: you have broken that array | 00:13 |
| nacc | conrmahr: and you want to install one of those 2 disks as an external drive on your server? | 00:13 |
| conrmahr | yes, but internal drive | 00:13 |
| nacc | conrmahr: ok | 00:13 |
| nacc | conrmahr: so to make the formerly RAID disk visible to your new system, you should just need to format it (partition table and all) and put a fs on it | 00:14 |
| conrmahr | i'm sick of Synology. I want to use Ubuntu Server. | 00:14 |
| nacc | conrmahr: but then I really don't understand the last question: "Can I delete on of them on Ubuntu Server so I can transfer the backup HDD from the NAS to the Ubuntu Server HDD over the network?" | 00:14 |
| nacc | conrmahr: a) delete one of "what" on Ubuntu Server? | 00:15 |
| nacc | conrmahr: b) transfer a HDD over the network? | 00:15 |
| conrmahr | ok I have about 3 TBs of data on HDD 1 | 00:15 |
| conrmahr | and HDD 2 is a backup | 00:15 |
| JanC | backup? | 00:15 |
| nacc | conrmahr: RAID mirror or backup? | 00:16 |
| conrmahr | exact mirror | 00:16 |
| nacc | conrmahr: so ideally, you'd just plug in HDD2 (or 1) into your server and it would work, but it's formatted as RAID member? | 00:17 |
| conrmahr | so I want to take HDD2, delete everything and format it for Ubuntu Server, then over the network copy all the files from HDD1 with a network mount. | 00:17 |
| nacc | conrmahr: so if it's plugged into your server now, I'd expect you to be able to edit the partition table (fdisk, cfdisk, parted) and delete all partitions and create a new one | 00:17 |
| nacc | *new partition | 00:18 |
| conrmahr | I tried that but it didn't reconize because of the format that Synology uses. | 00:18 |
| JanC | Synology uses standard linux RAID AFAIK | 00:18 |
| nacc | conrmahr: why would you need to recognize the format that Synology uses? | 00:18 |
| conrmahr | ok | 00:18 |
| nacc | conrmahr: you're deleting all the partitions, afaict | 00:19 |
| sarnold | recognizing the format might allow skipping the repartition and reformat steps :) | 00:19 |
| conrmahr | when i do "sudo fdisk -l" | 00:19 |
| nacc | sarnold: that's true, but conrmahr seemed ok/resigned to that :) | 00:19 |
| JanC | actually, I guess his server recognizes the raid mirror & automatically starts it as a degraded RAID | 00:19 |
| JanC | or something | 00:20 |
| nacc | JanC: oh that could be ... | 00:20 |
| sarnold | JanC: ooh | 00:20 |
| JanC | that would explain the "in use" | 00:20 |
| nacc | JanC: didn't think of that | 00:20 |
| nacc | conrmahr: need to step away, sorry, but if JanC is right, you'll need to stop that case (possibly with mdadm) | 00:21 |
| conrmahr | what do i do after | 00:21 |
| conrmahr | actually looks like i got it removed | 00:21 |
| conrmahr | i don't see /dev/md127 anymore | 00:21 |
| conrmahr | i do i create a new primary partition after i type | 00:22 |
| conrmahr | $sudo parted /dev/sbd | 00:22 |
| conrmahr | so i did "(parted) print" | 00:26 |
| conrmahr | and it says the Partition Table: gpt | 00:26 |
| conrmahr | with no partition | 00:26 |
| sarnold | alright, now you've got to decide what you want the disk to do on ubuntu -- if you want to use mdadm to create a mirror, then format ext4, then copy data.. or use zfs to create a degraded mirror, add a filesystem, then copy data over.. | 00:28 |
| conrmahr | So I just want it to store media files | 00:29 |
| Velus-universe | what is happening here E: Sub-process /usr/bin/dpkg returned an error code (1) | 00:29 |
| conrmahr | i have a 60GB SDD for just the Ubuntu OS | 00:29 |
| conrmahr | I"m just wanting to set up these 2 WD Red 4TB HDDs as secondary drives for a NAS. | 00:31 |
| JanC | conrmahr: you want to create a new RAID? | 00:32 |
| sarnold | Velus-universe: it means "look higher in the log to find out what the error is" | 00:32 |
| conrmahr | no, I just want to get this working and not lose my data. | 00:32 |
| Velus-universe | in what log | 00:33 |
| JanC | so you want both drives as separate disks in the end? | 00:33 |
| conrmahr | yes | 00:33 |
| conrmahr | Install them like they are fresh out of the box | 00:34 |
| conrmahr | with nothing on it | 00:34 |
| JanC | well, if there is nothing on it, you also can't put files on it ;) | 00:34 |
| sarnold | Velus-universe: the apt-get run | 00:35 |
| conrmahr | ha, true. But I was hoping to clean one, transfer the data over the network, then clean the next one and install it. | 00:35 |
| Velus-universe | ok its hissing about a folder missing | 00:35 |
| JanC | you'll need a partition & a filesystem, but you could also make it such that you have one filesystem spread over both, etc. (there are lots of options...) | 00:36 |
| Velus-universe | http://pastebin.com/e0Jk8GcX that is the log with it | 00:37 |
| conrmahr | when you say file system, you mean like OS? | 00:37 |
| JanC | no, the filesystem is what remembers which file, directory, etc. is where on the disk | 00:37 |
| JanC | like ext4, NTFS, FAT32, etc. | 00:37 |
| sarnold | Velus-universe: check dmesg to see if you have errors, from the scsi layer or memory problems.. | 00:38 |
| conrmahr | oh right | 00:38 |
| sarnold | Velus-universe: something like dmesg | tail -30 ought to be enough to give you an idea if there's anything serious | 00:38 |
| conrmahr | so would you recommend NTFS if I was sharing it with other Mac and PC computers? | 00:38 |
| JanC | if you mean sharing over the network, then no | 00:39 |
| sarnold | what do you mean by "sharing it with"? | 00:39 |
| conrmahr | yeah sharing over the network | 00:39 |
| conrmahr | i want to make the device a NAS/Media Server | 00:39 |
| Velus-universe | http://pastebin.com/wJ7Y88i1 | 00:39 |
| sarnold | Velus-universe: good | 00:40 |
| sarnold | Velus-universe: check df -h -- are any filesystems at 100%, or close to it? | 00:40 |
| Velus-universe | nope all 1 or 2 % | 00:41 |
| Velus-universe | or 0 % | 00:41 |
| sarnold | Velus-universe: alright, try apt-get install -f | 00:41 |
| Velus-universe | http://pastebin.com/TQ62TRZB | 00:42 |
| JanC | might also be useful to check df -i | 00:42 |
| Velus-universe | same all 1% | 00:43 |
| sarnold | JanC: definitely good idea, it's something I overlook all the time.. | 00:44 |
| conrmahr | so any recommendations on the filesystem for NAS? | 00:44 |
| JanC | conrmahr: it all depends on how you want to use it, how much RAM you have, what Ubuntu version this is, etc. | 00:45 |
| JanC | and the type of files too | 00:45 |
| conrmahr | only 8GB DDR3 now | 00:45 |
| sarnold | conrmahr: i'm partial to zfs; it provides compression, mirroring, snapshots, and other cool features; see https://pthree.org/2012/12/04/zfs-administration-part-i-vdevs/ for a great series of blog posts that describe it well | 00:45 |
| conrmahr | but will upgrade to 16GB later | 00:46 |
| JanC | and you could later add the second drive to the same filesystem with ZFS | 00:46 |
| conrmahr | basically a lot of mpg, mkv files for TV and Movies | 00:46 |
| Velus-universe | i wonder why this aint working then | 00:46 |
| conrmahr | that I will run Plex Media Server over | 00:46 |
| sarnold | Velus-universe: I'm not sure. the next step is to save aside your dovecot configuration if you hve any, apt-get purge the docvecot package, then apt-get install the package again | 00:47 |
| Velus-universe | hwo do i patget purge | 00:47 |
| Velus-universe | and also i got rid of the dovecot to start again | 00:48 |
| sarnold | "apt-get purge dovecot" should do it | 00:48 |
| Velus-universe | im still getting the problems | 00:48 |
| Velus-universe | ok i rmeoved dovecot-lmtpd and it worked now | 00:50 |
| conrmahr | so is zfs easy to use for a noob? | 00:50 |
| sarnold | conrmahr: I think it's easier than mdadm or lvm | 00:51 |
| sarnold | probably nothing comes close to the ease of the synology | 00:52 |
| conrmahr | well once i have it set up i should be golden | 00:53 |
| conrmahr | I worked on RHEL and Ubuntu VPSs for web development | 00:54 |
| conrmahr | but never had to install hardware | 00:55 |
| conrmahr | where's the zfs ubuntu repo? This looks like Debian. | 00:57 |
| sarnold | heh, I know the feeling, I've used linux for years, but only installed it a few times. the installer ... | 00:57 |
| sarnold | conrmahr: in xenial, zfs is included; in wily, it's done via dkms packages. earlier than that, and you'll want to use some pakages from a PPA instead | 00:57 |
| conrmahr | i have 14.04.4, is that xenial? | 00:59 |
| conrmahr | so i can just do apt-get? | 00:59 |
| sarnold | that's trusty | 00:59 |
| conrmahr | what's PPA? | 00:59 |
| sarnold | a personal package archive; in this case, darik horn has zfs packages built for precise, trusty, and wily here https://launchpad.net/~zfs-native/+archive/ubuntu/stable | 01:00 |
| conrmahr | gotcha | 01:01 |
| JanC | alternatively, you could try installing Ubuntu 16.04 (xenial) beta instead | 01:03 |
| sarnold | that's what I did last week with my new computer | 01:03 |
| sarnold | so far so good | 01:03 |
| JanC | final release of 16.04 should be in two weeks, I think | 01:04 |
| sarnold | it only took two or three minutes to set up my nine-drive zfs array | 01:04 |
| JanC | nice :) | 01:05 |
| conrmahr | which zfs package should i install for trusty | 01:12 |
| conrmahr | zfs-fuse? | 01:12 |
| sarnold | no, skip that | 01:12 |
| conrmahr | i installed the ppa repo | 01:12 |
| conrmahr | don't i have to install the package? | 01:12 |
| sarnold | you do, but zfs-fuse is an ancient and terrible thing | 01:13 |
| conrmahr | oh | 01:13 |
| sarnold | install zfs-linux -- hopefully that'll install whatever else it needs | 01:13 |
| conrmahr | how about ubuntu-zfs? | 01:13 |
| sarnold | that might install everything from his repository in one go; using zfs for the / filesystem is a bit difficult, I wonder if that packge exists to help the zfs root case.. | 01:15 |
| conrmahr | i did a apt-cache search | 01:16 |
| conrmahr | and it says | 01:16 |
| conrmahr | ubuntu-zfs - Native ZFS filesystem metapackage for Ubuntu. | 01:16 |
| conrmahr | zfs-dkms - Native OpenZFS filesystem kernel modules for Linux | 01:17 |
| sarnold | might as well go with ubuntu-zfs. it'll probably do the right thing. | 01:18 |
| conrmahr | done | 01:19 |
| conrmahr | so can you walk me through how to create a new filesystem and partition? | 01:20 |
| conrmahr | with parted right? | 01:20 |
| sarnold | zpool create -n /dev/disk/by-id/.... --- pick the device name for the 4tb drive | 01:20 |
| sarnold | zpool create will know how to partition and format the disk | 01:20 |
| conrmahr | oooh | 01:21 |
| conrmahr | i like i like | 01:21 |
| sarnold | dang, i've got to take off in a minute.. | 01:21 |
| sarnold | the -n is a no-op mode, to make sure it looks fine | 01:21 |
| sarnold | take it off if you like the way the command output looks | 01:21 |
| sarnold | and re-run it.. | 01:21 |
| conrmahr | FRIDAY NIGHT! | 01:21 |
| conrmahr | ok | 01:22 |
| sarnold | ah I got the command wrong, "zpool create -n poolname /dev/disk/by-id/..." | 01:22 |
| conrmahr | so if the disk is /dev/sdb | 01:23 |
| conrmahr | it would be "zpool create -n poolname /dev/sdb" | 01:24 |
| conrmahr | do i have to create a poolname? | 01:24 |
| sarnold | the downside to the shortname /dev/sdb rather than /dev/disk/by-id/ata-WD_..... is that the long name shouldn't change; hte short name can change based on which drives are brought up first by the bios or os | 01:25 |
| sarnold | yeah, a lot of people pick 'tank' or 'pool' or 'srv' | 01:25 |
| patdk-lap | heh | 01:25 |
| patdk-lap | aggr :) | 01:25 |
| sarnold | aggr? never seen that one before :) | 01:25 |
| patdk-lap | netapp | 01:25 |
| sarnold | ahh | 01:25 |
| conrmahr | i can find the long name right? | 01:26 |
| patdk-lap | export and import it | 01:26 |
| sarnold | conrmahr: alright, after that, "zfs set compression=lz4 poolname ; zfs set atime=off poolname ; zfs set checksum=sha256 poolname ; zfs create poolname/movies ; zfs list" :) | 01:26 |
| sarnold | patdk-lap: good point. | 01:26 |
| sarnold | conrmahr: time to run, have fun :) | 01:26 |
| patdk-lap | why checksum sha256? | 01:27 |
| patdk-lap | that would make it slow | 01:27 |
| sarnold | because I trust it more than fletcher4 | 01:27 |
| conrmahr | i like trust | 01:27 |
| patdk-lap | sure, it's *better* | 01:27 |
| patdk-lap | but the level of difference is really small :) | 01:27 |
| sarnold | actually | 01:27 |
| patdk-lap | have to have an ecc error from the disk first | 01:28 |
| conrmahr | i do need my p0rn fast though | 01:28 |
| sarnold | ... conrmahr if you're not going to have any redundancy anyway, you don't need the better checksum. heh. | 01:28 |
| sarnold | patdk-lap: hmm. I hadn't thoght about that. | 01:28 |
| conrmahr | so like later | 01:28 |
| patdk-lap | I would keep with default checksum, unless your going attempt dedup | 01:28 |
| conrmahr | when i add the 2nd drive | 01:28 |
| conrmahr | and i just want to clone it | 01:28 |
| sarnold | patdk-lap: .. is that why pool scrub runs at only 400 MB/s? :) | 01:28 |
| conrmahr | would i just do an rsync? | 01:29 |
| patdk-lap | sarnold, no | 01:29 |
| patdk-lap | that more has to do with iops | 01:29 |
| patdk-lap | and well, transaction sizes | 01:29 |
| patdk-lap | so much metadata to read and verify per block of data | 01:29 |
| patdk-lap | well, figured out why some of my disks are going so slow :( | 01:30 |
| patdk-lap | 3 bad bbwc | 01:30 |
| sarnold | conrmahr: you'll use "zpool attach". DO NOT USE ZPOOL ADD. write that down. | 01:30 |
| patdk-lap | and 4 bbwc without any ram installed | 01:30 |
| sarnold | patdk-lap: awwww | 01:30 |
| sarnold | ouch | 01:30 |
| patdk-lap | I never put any workloads on them before I setup this test | 01:31 |
| patdk-lap | so didn't notice or really care | 01:31 |
| conrmahr | where does it say zpool add? | 01:31 |
| sarnold | conrmahr: the zpool manpage. | 01:31 |
| patdk-lap | zpool add = making raid0's | 01:31 |
| sarnold | conrmahr: it's way too easy for people to screw this up :) I've seen three people make that mistake already... | 01:31 |
| patdk-lap | had an l2arc die monday :( | 01:32 |
| patdk-lap | caused the server to panic | 01:32 |
| sarnold | patdk-lap: awwwww :( | 01:32 |
| sarnold | yikes | 01:32 |
| patdk-lap | but that was illumos though | 01:33 |
| * patdk-lap wonders if it is worth attempting to use luster | 01:34 | |
| patdk-lap | so far, gluster has been horrible | 01:34 |
| patdk-lap | or, lustre | 01:34 |
| conrmahr | so i ran everything | 01:36 |
| conrmahr | i get cannot open 'data1'; dataset does not exist | 01:36 |
| conrmahr | that was my poolname | 01:36 |
| conrmahr | oh creat | 01:36 |
| conrmahr | crap | 01:36 |
| conrmahr | i didn't remove the -n | 01:36 |
| conrmahr | what's this command? | 01:37 |
| conrmahr | zfs set attime=off data1 ; | 01:38 |
| conrmahr | it errors out | 01:38 |
| patdk-lap | one t | 01:38 |
| patdk-lap | atime, not at time | 01:38 |
| conrmahr | beautiful | 01:38 |
| conrmahr | now i just need to transfer the files! | 01:41 |
| patdk-lap | rm does that good, really quick too | 01:41 |
| conrmahr | that's a joke right? | 01:41 |
| patdk-lap | :) | 01:41 |
| conrmahr | how about rm * | 01:42 |
| conrmahr | oops, meant to put it here | 01:47 |
| conrmahr | would you use "$ cp" to move 3TBs of data? | 01:48 |
| patdk-lap | what is it? | 01:48 |
| conrmahr | media files | 01:48 |
| conrmahr | i mounted the network drive to /mnt | 01:48 |
| patdk-lap | rsync -avwP --inplace, should do it nicely | 01:48 |
| patdk-lap | the v and P are optional | 01:49 |
| conrmahr | what's the directories look like | 01:49 |
| patdk-lap | two directories? | 01:49 |
| conrmahr | i mean which is first and second | 01:49 |
| patdk-lap | source dest | 01:49 |
| patdk-lap | put a / on the end, if you don't want it to copy the source folder itself | 01:49 |
| patdk-lap | but just stuff in it | 01:49 |
| conrmahr | and what are the v and P do? | 01:50 |
| patdk-lap | v shows you the files as it copies | 01:50 |
| patdk-lap | P gives you progress per file | 01:50 |
| Velus-universe | patdk-lap, i have not got soem of it working by my dovecot wont start and i get nothing in the logs | 02:57 |
