[06:21] <cpaelzer> good morning
[06:42] <cpaelzer> I realized I like parentheses too much :-( given how often I wish there would be a general form of multi level
[06:42] <cpaelzer> you know (what I [not really] mean)? :-)
[06:44] <DirtyCajun> so... using iostat i have a 12 Disk raid6. No underlying drive is using more than 50% but dm-2 (the lvm lv) is at 100%. is there a way to optimize this?
[06:50] <cpaelzer> DirtyCajun: this isn't a problem
[06:51] <cpaelzer> DirtyCajun: essentially it means "something is in flight" at any time
[06:51] <cpaelzer> but it is not a "limit" as it would be with old style sequential queue disks
[06:51] <cpaelzer> due to deep async queues on modern devices and raid on top this is not like 10 years ago where 100% means you can't go faster
[06:52] <DirtyCajun> cpaelzer, ok, if that is a non-issue, i then need to optimize the way that i am transferring the data to the disk to increase speed?
[06:52] <cpaelzer> check the iostat man page on %util - it even says "But for devices serving requests in parallel, such as RAID arrays and modern SSDs, this number does not reflect their performance limits."
[06:52] <cpaelzer> DirtyCajun: so your question converts to "how can I go faster" is that right?
[06:53] <DirtyCajun> yes. I am currently using bbcp so i can tweak threads unless i am hitting another bottleneck i dont see
[06:53] <DirtyCajun> box to box its going from a raid6 to a raid6 on a 10Gbps backplane
[06:54] <DirtyCajun> thoughts?
[06:54] <cpaelzer> busy - back in a few mins DirtyCajun
[06:55] <DirtyCajun> ok
[06:58] <DirtyCajun> cpaelzer, actually... (for when you get back) according to a raid calculator my raid6 should only be getting about 180MB/s full write... so i assume im getting above that because im on the very begging of the disk
[07:06] <cpaelzer> DirtyCajun: yes on spinning disks the beginning can be somewhat faster
[07:07] <DirtyCajun> just thew me off because of the %util per disk
[07:07] <DirtyCajun> im just impatient because its 48TB :P
[07:07] <cpaelzer> so do you need/want to be faster - or did you just wonder about the 100%?
[07:09] <cpaelzer> the 50% on the actual disks seem to indicate that you could go faster if you push faster
[07:09] <cpaelzer> but performance always depends on details, so take that sentence above with a grain of salt
[07:09] <cpaelzer> s/push faster/push harder (i.e. do more i/O)
[07:10] <lordievader> Good morning
[07:10] <cpaelzer> hi lordievader
[07:10] <lordievader> Hey cpaelzer
[07:10] <lordievader> How are you doing this monday morning?
[07:13] <cpaelzer> lordievader: a bit nervous for non IRC comatible reasons, but other than that good :-)
[07:13] <cpaelzer> and how is your week starting lordievader?
[07:13] <cpaelzer> DirtyCajun: I'm no bbcp expert, but more streams could do what you need
[07:13] <lordievader> Like normal. I suppose that is a good thing 😃
[07:13] <cpaelzer> (to push harder and therby go faster)
[07:14] <cpaelzer> yeah normal=good lordievader
[07:14] <DirtyCajun> i bumped it from 4 streams to 8 and its literally didnt change anything
[07:14] <lordievader> Thanks for the confirmation :)
[07:14] <DirtyCajun> it think its gonna be what its gonna be
[07:15] <cpaelzer> DirtyCajun: if you are ok with it I'm fine :-)
[07:15] <DirtyCajun> and its all over the board. its just the average is about what i said above
[07:15] <DirtyCajun> http://termbin.com/zc63
[07:16] <DirtyCajun> crazy how it can hit 53 as a low and 550 as a high in less than 30 sec
[07:17] <cpaelzer> DirtyCajun: depending how it copies I/O block sizes are very important
[07:17] <DirtyCajun> i have it set at 4M blocksizes
[07:17] <cpaelzer> so if it copied files as-is a bunch of small files might be slow and huge one fast - depending on how it writes to the target disk
[07:17] <DirtyCajun> none of these files are <10GB
[07:18] <cpaelzer> well that qualifies as non-small :-)
[07:18] <DirtyCajun> so it SHOULD be sequential read and write
[07:18] <DirtyCajun> hahaha
[07:18] <DirtyCajun> its more all over the place than my wife
[07:18] <DirtyCajun> last one went at 439MB/s
[07:19] <DirtyCajun> then it will just crap the bed for a few seconds. Im assuming something to do with write cache/ dumping from write cache during that itme
[07:19] <DirtyCajun> time
[07:19] <cpaelzer> you might be hunting just a bad average calculation algorithm
[07:19] <DirtyCajun> thats true.
[07:19] <cpaelzer> maybe if you'd report every 30 seconds you never would have spent time to thnk about it
[07:19] <DirtyCajun> yeah. im  looking at the 1 sec differences not the average on the right. fair.
[07:20] <cpaelzer> and it is documented to scale the tcp window sizes
[07:20] <cpaelzer> so if it hits a max and throttles back with so much in flight you might veen have such a short drop before you are back up
[07:21] <DirtyCajun> i set it to 60 second polling and im gonna go chill out for a bit. Its pumping through to grafana so i can look at it that way as an overall stat
[07:21] <DirtyCajun> thanks for the time cpaelzer
[07:28] <cpaelzer> yw DirtyCajun
[09:06] <zioproto> good morning
[09:07] <zioproto> I am following the story of this bug for Ubuntu Xenial https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1738219
[09:07] <zioproto> Fix Commit is the last step before Fix Released ?
[09:08] <zioproto> I mean, packages should be available in proposed, right ?
[09:11] <zioproto> I added http://ch.archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages to my source list
[09:12] <zioproto> but how do I understand which kernel version has the fix for that bug ?
[09:12] <zioproto> I did
[09:12] <zioproto> apt changelog linux-image-generic
[09:12] <zioproto> but I cannot find the bug in the changelog
[14:10] <frickler> jamespage: would be nice if you could target this for bionic https://bugs.launchpad.net/ubuntu/+source/ceph/+bug/1750376
[14:22] <jamespage> frickler: yes of course
[14:23] <jamespage> frickler: btw ceph-disk is not deprecated as of 12.2.2 (that got reverted)
[14:23] <jamespage> it will be as of next release tho
[14:23] <jamespage> with removal the one after
[14:24] <frickler> jamespage: well, http://docs.ceph.com/docs/master/ceph-volume/#migrating still claims so
[14:24] <frickler> jamespage: but yeah, ceph folks are doing lots of (not so) funny things currently
[14:26] <jamespage> I was going on the ML thread from pre-christmas
[14:31] <ahasenack> rbasak: hi, I'm doing a dist-upgrade on a xenial server, and this was shown:
[14:32] <ahasenack> The following packages will be REMOVED:
[14:32] <ahasenack>   python-certbot
[14:32] <ahasenack> rbasak: did that package change names?
[14:32] <ahasenack> hm, python3-certbot is a NEW install
[14:32] <ahasenack> I have python-certbot 0.19.0-1+ubuntu16.04.1+certbot+1 installed
[14:33] <ahasenack> apt-cache policy doesn't show from where, just the local dpkg db
[14:33] <ahasenack> maybe it was a package from upstream?
[14:33] <ahasenack> fginther: hi, do you remember where you installed that python-certbot package from? It's landscape's jenkins
[14:33] <ahasenack> oh, holiday probably
[14:35] <rbasak> ahasenack: that doesn't sound like a package from the archive
[14:35] <ahasenack> oh, you are right
[14:35] <ahasenack> python3-certbot comes from a ppa
[15:37] <rbasak> ahasenack: could you see if https://jenkins.ubuntu.com/server/job/git-ubuntu-ci/288/rebuild works for you please? It just seems to redirect me back without starting a rebuild.
[17:02] <ahasenack> rbasak: checking that url
[17:04] <ahasenack> rbasak: I see a build, and I'm not logged in. No button to trigger a rebuild. let me login now
[17:04] <ahasenack> rbasak: now I see the "rebuild" link on the left menu
[17:04] <rbasak> Ah
[17:04] <rbasak> I appear to be logged out.
[17:04] <rbasak> Sorry!
[17:04] <rbasak> Thank you for looking for me.
[17:04] <rbasak> I should have thought to check that.
[17:05] <ahasenack> it's definitely not obvious
[17:17] <ahasenack> rbasak: thanks for the ua-tools review. Are you tagging and uploading?
[17:17] <rbasak> ahasenack: already done :)
[17:17] <ahasenack> nice, thanks
[17:18] <ahasenack> I'll keep an eye on excuses
[17:24] <j4g0> i have a folder with chmod 2770 to which i'd like to mount a network share. https://wiki.ubuntu.com/MountWindowsSharesPermanently does not tell me how i could recreate the permissions on the folder, where should i read up on that?
[17:32] <ahasenack> j4g0: are you sharing between two linux boxes? Or the server is windows and the client is linux? Where is this chmod?
[17:33] <j4g0> server is a kazooli sme server 9.2, which is based on centOS, the box i want to mount on is ubuntu 16.04. The folder i have is on my ubuntu box.
[17:35] <j4g0> i only found a description on how to set the gid in the fstab file on the mounting box but that only means the folder is set to chgrp <funny_name_hereY
[17:36] <ahasenack> setting a gid is not the same as permissions (2770)
[17:36] <j4g0> true, hence my question on how i could recreate those permissions
[17:36] <ahasenack> what is it you want to do, force all files to be owned by a certain group?
[17:37] <j4g0> yes, i want all files in said folder to belong to a certain grp
[17:37] <ahasenack> the server part, if that's samba (most likely it is) has options for that, per share
[17:37] <j4g0> ah ok, tyvm
[17:37] <j4g0> then i know where to look that up
[17:37] <ahasenack> check the smb.conf manpage, look for the "force group" parameter
[17:38] <ahasenack> there are other force <thing> parameters
[17:39] <ahasenack> that won't change already existing files
[17:39] <ahasenack> if you need those to be owned by a specific group on the client side, then I think you need to look at mount.cifs options
[17:39] <ahasenack> specifically, forcegid
[17:40] <ahasenack> but if that gid belongs to a different group on your client then it does on the server, you will see different names when listing the files
[17:40] <ahasenack> different group owners, I mean
[17:41] <j4g0> i'll try the mount.cifs first then, tyvm
[20:17] <Pinkamena_D> Hey, I am having an issue where the right shift key will not work while connected over xrdp. The left one works ok. I have tried the suggested steps checking the layouts in /etc/xrdp. The Keycodes match for 50 and 62 correctly. I have tried to map the right shift key to the left action also as a last ditch action but this just makes many other keys not work lol.
[20:19] <HardcoreKrypton> ?
[20:19] <Pinkamena_D> question mark for me? :)
