| Ublx | i have a problem: i removed an external hard disk without unmounting before and now 1 of 3 partitions has the error: "error unlocking, failed to activate, file exists". it would be great if someone could help me. thanks. | 00:10 |
| === xfnw is now known as vulpine | ||
| guiverc | Ublx, did you `fsck` (file-system check) the partition(s)? | 00:31 |
| Ublx | no, guiverc. what should I type: just fsck or any arguments? | 00:45 |
| TJ- | Ublx: sounds like you have LUKS encrpyted, and the device-mapper files still exist from when you ripped it out | 00:46 |
| Ublx | TJ-: yes, it's LUKS encrypted | 00:46 |
| guiverc | Ublx, I'd boot a live system & `fsck` from there; use whatever tool you prefer, command, gparted, kde partition manager etc (ie. GUI is okay too). adjust for your box but take note of TJ- first (I didn't see what he does) | 00:46 |
| TJ- | guiverc: this is a LUKS/device-mapper issue | 00:47 |
| Ublx | my internal disk is okay, it's an external hard disk | 00:47 |
| Ublx | what should i do TJ- ? | 00:47 |
| TJ- | Ublx: OK, so you need to 1) identify the device-mapper name that is stale (the LUKS device name) by looking at "ls /dev/mapper/" then 2) manually removing the stale name with "sudo dmsetup remove THE_STALE_NAME" - after that LUKS can unlock and recreate the name correctly | 00:48 |
| Ublx | it says exactly "Error unlocking /dev/sdc3: Failed to activate device: File exists" | 00:48 |
| TJ- | Ublx: I assume you've an /etc/crypttab with names to be given to the unlocked device, e.g. maybe "sdc3_encrypted" | 00:49 |
| TJ- | Ublx: in my case the names are LUKS_something_meaningful | 00:49 |
| Ublx | hm, there is one with luks-e05b2f.... is that the one? | 00:50 |
| TJ- | Ublx: might be - the e05fb... could be a GUID of the device. compare that with "sudo blkid /dev/sdc3" | 00:51 |
| Ublx | There's sda5_crypt, too? That's also not my internal drive, as far I as know from df. | 00:51 |
| TJ- | Ublx: if that matches you've got the correct one | 00:51 |
| TJ- | Ublx: 'sda' is usually the first storage device discovered which we'd normally expect to be the boot device | 00:51 |
| Ublx | blkid has no output | 00:52 |
| TJ- | Ublx: that is strange | 00:52 |
| Ublx | I have only these: /dev/sda /dev/sda1 /dev/sda2 /dev/sda5 /dev/sr0 | 00:53 |
| Ublx | And of course, I unplugged the external hard drive completely. | 00:53 |
| TJ- | you'd expect blkid to report something similar to this for a LUKs partition: " /dev/nvme0n1p2: UUID="db9cd343-9ca9-4115-845f-d27943c14437" TYPE="crypto_LUKS" PARTLABEL="Linux dm-crypt" PARTUUID="15f7095d-5bbb-4a43-8324-9867b91dc7d6" | 00:53 |
| Ublx | hm... | 00:54 |
| TJ- | Ublx: check sda5 then, with "sudo blkid /dev/sda5" and see if its GUIDs match the earlier mentioned | 00:54 |
| TJ- | Ublx: it is possible that when the disk was removed it was known as sdc and now is sda | 00:55 |
| Ublx | it's just followed by an output and does nothing with sda5, right? | 00:55 |
| TJ- | Ublx: you'd expect a report to indicate sda5 is LUKS/encrypted | 00:56 |
| Ublx | /dev/sda5: UUID="43f8104c-c836-44a0-a0eb-c7ffe478abbb" TYPE="crypto_LUKS" PARTUUID="4ebfa39c-05" | 00:56 |
| Ublx | but my local drive is also encrypted | 00:56 |
| TJ- | Ublx: that may be it then; check by looking at the tree shown with "lsblk" -- follow sda > sda5 > ... because that will show what is mounted, and where | 00:58 |
| TJ- | Ublx: basically, you're got to avoid removing the active device(s) by identifying the stale device-mapper device that belonged to the removed disk | 00:59 |
| Ublx | no, the tree ends at the root and swap as you expected. :( | 00:59 |
| TJ- | Ublx: for sda5? so that's active then, good. Which by a process of elimination indicates that "luks-e05b2f..." is likely the suspect | 01:00 |
| Ublx | 'sr0 rom' is the only 'curious' I would say. | 01:00 |
| TJ- | Ublx: so now check the status of that device with "sudo dmsetup info luks-e05b2f ..." (put in the COMPLETE GUID as shown by "ls /dev/mapper/" ) | 01:00 |
| TJ- | sr0 = SCSI Read-Only device 0 | 01:01 |
| TJ- | a.k.a. CD-ROM :) | 01:01 |
| remline | Do I see correctly that 'focal-backports' pretty much has only one program in it, i.e., cockpit? | 01:01 |
| Ublx | TJ-: I have the output. What do you need? ACTIVE, LIVE, .. | 01:02 |
| TJ- | Ublx: if it is reporting as ACTIVE, LIVE that might not be the stale one | 01:07 |
| TJ- | Ublx: how many devices does "sudo dmsetup ls" report ? | 01:07 |
| TJ- | Ublx: if the system is using LVM then you'll get the LVM logical volumes as well as any LUKS devices | 01:07 |
| Ublx | 4 devices | 01:08 |
| TJ- | Ublx: so 2 crypto and 2 logical volumes? can you deduce that from the device names? | 01:09 |
| Ublx | I have root, swap, sda5_crypt (what seems to lead to the first two) and luks-... | 01:09 |
| TJ- | OK, that sounds correct and understandable | 01:09 |
| Ublx | puh | 01:10 |
| TJ- | so the confusion still remaining is the error report mentioned sdc3 but you said there is no sdc* reported (does 'lsblk' not show an sdc ? ) | 01:10 |
| TJ- | Ublx: did the error come from a GUI program, such as file manager? | 01:11 |
| Ublx | no, should I plug the drive in and then check lsblk? | 01:11 |
| Ublx | TJ-: yes, from nautilus | 01:11 |
| Ublx | i do almost anything from cli but not mounting. | 01:12 |
| TJ- | Ublx: OK, so the file manager uses udisks under the hood to control devices, so my suspicion is it is trying to read the missing device and getting confused | 01:13 |
| Ublx | ok | 01:13 |
| Ublx | thank you so much for helping me. | 01:13 |
| TJ- | Ublx: see if this reports anything: "udisksctl info -b /dev/mapper/luks-e05b2f...." (complete that UUID again!) | 01:14 |
| TJ- | Ublx: udisksctl is the command-line interface to udisks | 01:14 |
| Ublx | output looks (too) fine | 01:16 |
| TJ- | Ublx: does it give a Mountpoint ? | 01:16 |
| TJ- | Ublx: presumably something like /media/$USER/luks-$UUID | 01:17 |
| Ublx | /dev/dm-0 ? | 01:17 |
| TJ- | Ublx: no, that'll be the device. Towards the end of the report | 01:17 |
| Ublx | no /dev/dm-3 | 01:17 |
| TJ- | Ublx: e.g. for one of my LVs I see " MountPoints: /media/tj/SourceCode " | 01:18 |
| Ublx | /dev/mapper/luks-e05b2 ... and /dev/disk/by-id/dm ... nothing of the media/ folder | 01:18 |
| TJ- | Ublx: if there is an active mountpoint we need to first tell udisks to unmount it | 01:18 |
| TJ- | Ublx: good | 01:19 |
| Ublx | can't we just try to unmount it? | 01:19 |
| TJ- | Ublx: so now we just need to be sure what device that lives on!! | 01:19 |
| Ublx | what, if it's my local disk? | 01:19 |
| TJ- | Ublx: it isn't mounted | 01:19 |
| Ublx | ah | 01:19 |
| Ublx | I see. | 01:20 |
| TJ- | Ublx: all this effort is to try and avoid removing a device that is really in use! and so far we've not proved that one way or the other | 01:20 |
| Ublx | ok | 01:20 |
| Ublx | tried udisksctl info -b /dev/mapper/sda5_crypt and I also do not get any mount point. | 01:21 |
| TJ- | Ublx: Going back to the "sudo dmsetup info luks-..." did you notice (or check again) the "Open count:" -- that needs to be 0 for us to be able to remove it | 01:21 |
| TJ- | Ublx: it is possible sda5_crypt is swap. Check "cat /proc/swaps" | 01:21 |
| Ublx | open count is 1 | 01:22 |
| TJ- | Ublx: drat! can't remove it unless that is 0. '1' means something has an open handle on that device | 01:22 |
| Ublx | swapfile, yes | 01:22 |
| TJ- | Ublx: can you show me "pastebinit <( sudo blkid )" | 01:23 |
| Ublx | http://paste.ubuntu.com/p/Qp2pZkzqk8/ | 01:25 |
| Ublx | had to install pastebinit | 01:25 |
| Ublx | but cool, didn't know it's possible within the cli | 01:25 |
| TJ- | Ublx: OK, definitely no sign of anything there related to this phantom luks-e05bf2... | 01:27 |
| TJ- | Ublx: looks like you've been eaten by snaps though :) | 01:28 |
| Ublx | ugh | 01:28 |
| Ublx | i am nervous | 01:28 |
| calamari | Can anyone tell me the name of the repo that contains arm64 packages? It seems like the normal repos only have i386 and amd64. | 01:31 |
| TJ- | Ublx: let's see if you can 'close' the encryption. try "sudo cryptsetup close luks-e05bf2..." (complete UUID again!) | 01:31 |
| TJ- | Ublx: if the command doesn't report an error check if it has gone with "ls /dev/mapper/" | 01:31 |
| Ublx | Eh ... I just went to all the pids of ps aux | grep USERNAME and I found a running process on this (no more connected) partition ... | 01:33 |
| Ublx | ... killed it ... and it works ... | 01:33 |
| Ublx | so sorry | 01:33 |
| Ublx | but i didn't thought about it | 01:33 |
| Ublx | i just wanted to be sure that i close everything if we'll lock out the local disk. | 01:34 |
| TJ- | Ublx: so you've been able to remove the /dev/mapper/ node for it now? | 01:34 |
| Ublx | hm... where can i see it | 01:36 |
| Ublx | ah | 01:36 |
| Ublx | the 3 partitions are now connected and running ... 2 times luks... but it works. | 01:36 |
| Ublx | I have to note down all your commands. Learned so much. Thank you!! | 01:38 |
| calamari | I found it in ports.ubuntu.com. Can anyone tell me how to properly add that repo to sources.list? The normal way doesn't seem to be doing it. | 01:38 |
| TJ- | calamari: what is the 'normal way' that doesn't work? | 01:40 |
| calamari | TJ-: deb [arch=arm64] http://ports.ubuntu.com/ubuntu/ bionic main restricted universe multiverse | 01:40 |
| oerheks1 | sudo dpkg --add-architecture arm64 | 01:40 |
| calamari | TJ-: The repository 'http://ports.ubuntu.com/ubuntu bionic Release' does not have a Release file. | 01:41 |
| calamari | oerheks1: already did that | 01:41 |
| TJ- | calamari: there is no "/ubuntu" directory; delete that. | 01:41 |
| TJ- | calamari: as in "deb [arch=arm64] http://ports.ubuntu.com/ bionic main restricted universe multiverse " | 01:42 |

| ducasse | vincenzoml: i don't trust btrfs and use zfs instead | 17:34 |
| === ijohnson is now known as ijohnson|lunch | ||
| vincenzoml | ducasse: yes I know zfs is way more established; but don't have the expertise to just start using that on a 10tb drive that K people will fill up. | 17:43 |
| vincenzoml | I just wonder if there are known pitfalls of btrfs specifically on large drives. | 17:44 |
| cbreak | I haven't heard of anything that makes btrfs problematic with larger disks more than it does with smaller ones | 17:45 |
| cbreak | but ... since it is problematic, I wouldn't risk it either | 17:45 |
| cbreak | I use zfs with success though. It's nice :) | 17:46 |
| vincenzoml | cbreak, I am not an expert; but I have used btrfs for like 3-4 years on three machines with no significant problems, except when I had a failing RAM block | 17:46 |
| vincenzoml | but cbreak ducasse I am curious to hear: | 17:46 |
| vincenzoml | since this is a production machine, what are the risks you think should make me think again and use zfs instead | 17:47 |
| cbreak | do you have redundancy? | 17:47 |
| vincenzoml | and about zfs is it easy to add a second drive to zfs and make a raid without reformatting the first drive? | 17:47 |
| vincenzoml | cbreak, I have only used mirroring | 17:48 |
| vincenzoml | with two drives indeed | 17:48 |
| cbreak | with zfs you can add more disks to make it a mirror | 17:48 |
| cbreak | you won't get space by doing that obviously | 17:48 |
| vincenzoml | cbreak, ok great, that's important (and a reason why in the first place btrfs was ok to me) | 17:48 |
| cbreak | you can also add more vdevs to get more space (via "striping" (not real striping)), but that won't give you redundancy | 17:48 |
| cbreak | but you can not create a raidzX vdev from an existing vdev | 17:49 |
| vincenzoml | so I cannot first extend and then mirror, that's what you mean (I'm not an expert in filesystems and RAID, just need to make that machine large and safe) | 17:49 |
| cbreak | you can add new vdevs | 17:50 |
| cbreak | you can change single disk vdevs into n*mirror vdevs or back | 17:50 |
| cbreak | you can not change anything to a raidzX vdev | 17:50 |
| cbreak | you can get more space either by replacing harddisks in an existing vdev with bigger ones | 17:51 |
| cbreak | or by adding new vdevs | 17:51 |
| cbreak | zfs is more restrictive with this than btrfs | 17:51 |
| cbreak | but the benefit is that zfs doesn't shredder itself when you try to use those features :) | 17:51 |
| vincenzoml | sorry but what is raidzX in the first place :) Anyway in that machine I doubt we will ever have more than 4 10tb disks, and likely no more than 2. | 17:51 |
| vincenzoml | and if 2, they will be mirroring | 17:52 |
| cbreak | a raidzX (raidz1 / raidz2 / raidz3) is a parity-raid with 1, 2 or 3 disks worth of redundancy | 17:52 |
| vincenzoml | that's the most likely scenario | 17:52 |
| cbreak | similar to raid5, raid6 | 17:52 |
| vincenzoml | ah ok | 17:52 |
| cbreak | raidz1 doesn't make sense with less than 3 disks | 17:52 |
| vincenzoml | so the most likely scenario is that: 1) tomorrow I mount the drive, format it, and let it live happy for some months | 17:53 |
| cbreak | zfs isn't 100% self explanatory, and as with any powerful tool, you can destroy your data if you tell it to | 17:53 |
| vincenzoml | 2) then I buy a second drive, mount it, and it has to become a mirror, raid1-alike | 17:53 |
| cbreak | what you'd do is probably: create a pool on your drive | 17:54 |
| cbreak | create datasets on that pool (similar to thin-partitioned file systems) | 17:54 |
| cbreak | set up snapshot scheduling for those | 17:54 |
| cbreak | you can later add more redundancy or more striping to that pool | 17:54 |
| cbreak | without affecting any data on it | 17:54 |
| vincenzoml | ok, I could experiment with that a bit. | 17:55 |
| vincenzoml | Returning to btrfs what would be your main concern against using it? | 17:55 |
| cbreak | you can enable encryption, compression, ... on individual datasets | 17:55 |
| vincenzoml | I mean, so far, with RAID1 it behaved nicely for me. | 17:55 |
| vincenzoml | Ah ok | 17:55 |
| vincenzoml | so I can understand what a dataset is | 17:55 |
| vincenzoml | do dataset share the free space? | 17:55 |
| cbreak | you can look at snapshots via ls someDataset/.zfs/snapshots/... | 17:55 |
| vincenzoml | or are they fixed-size | 17:55 |
| cbreak | vincenzoml: they share the pool's available space | 17:56 |
| cbreak | but you can reserve space for datasets, or set max usage quotas | 17:56 |
| vincenzoml | Ok, So I could start with 1 dataset and create more later | 17:56 |
| vincenzoml | interesting! | 17:56 |
| cbreak | you should create datasets in some logical fashion | 17:56 |
| vincenzoml | so I could for instance, create 1 dataset; when a particular application starts filling up the whole drive, I can confine it to a newly created dataset with a quota, righ? | 17:56 |
| cbreak | maybe pool/media, pool/vms, pool/media/linux_isos, pool/media/blender_cloud_movies, ... | 17:57 |
| cbreak | vincenzoml: datasets are independent filesystems | 17:57 |
| cbreak | so if you want to do that, you have to copy the data over to the new dataset | 17:57 |
| vincenzoml | I see | 17:57 |
| cbreak | you can set mountpoints for those datasets individually | 17:58 |
| cbreak | but normally, they are mounted in the parent | 17:58 |
| cbreak | so if your pool is in /mnt/pool, then there's some /mnt/pool/media/linux_isos | 17:58 |
| vincenzoml | But consider the following situation: Just 1 dataset, filling up 98% of the hard drive; then I create a new dataset, and move data from the old one to the new one. Will this work or get stuck? | 17:58 |
| cbreak | you should really avoid filling zfs to more than 90% | 17:58 |
| vincenzoml | cbreak, but sh*t happens :) | 17:59 |
| cbreak | if you want to "move" data between datasets, you have to copy it | 17:59 |
| vincenzoml | cbreak, ah yes so with very large files that could become a problem | 17:59 |
| vincenzoml | but a dataset can be created in the pool at any time right? | 18:00 |
| cbreak | if you have space for it | 18:00 |
| cbreak | they take up a few kb in meta data | 18:00 |
| vincenzoml | then a question: with btrfs I have filled up the drive many times due to snapshots preserving too much old data. It worked to just remove the snapshots (even if it's a though decision). | 18:00 |
| vincenzoml | With ZFS you said, that is not advisable? | 18:00 |
| cbreak | it's not advisable, but possible | 18:01 |
