[02:04] <Pinkamena_D> Power failure on a little home server I was running. Nothing important on it at this point, but booting up leads to 'welcome to emergency mode' and I get EXT4-FS error while trying to remount RW. Is there any common items I can try to fix the FS before going for a reinstall?
[02:05] <tsimonq2> Pinkamena_D: Do you have a picture or something that you would be able to give us?
[02:05] <tsimonq2> Pictures speak 1000 words. ;)
[02:05] <Pinkamena_D> well I cant actually bring up an SSH session or anything to take a screenshot
[02:06] <tsimonq2> Got a smartphone? ;)
[02:06] <Pinkamena_D> I can, but likely I would be able to type faster whatever information you wanted
[02:08] <Pinkamena_D> hold on the phone is booting up
[02:08] <tsimonq2> What *exactly* does it say?
[02:10] <Pinkamena_D> http://pasteboard.co/f56uIdXva.jpg
[02:11] <Pinkamena_D> I also have a gparted and ubuntu boot usb available
[02:12] <tomreyn> Pinkamena_D: no space between "remount,rw"
[02:12] <Pinkamena_D> same result
[02:12] <tomreyn> force fsck
[02:13] <tomreyn> oh wait, not on /
[02:13] <Pinkamena_D> what is the best way to do that? Boot into gparted usb?
[02:13] <tomreyn> boot from a live cd, then force fsck
[02:13] <tomreyn> or live usb
[02:14] <Pinkamena_D> I had tried just a plain fsck /dev/sdd1 kind of deal before, if there some other option that I should try to fix it?
[02:21] <Pinkamena_D> also as an aside when you get the message "a start job is running for blablabla" and usually it takes 90 seconds to timeout is there any keyboard shortcut you can use to skip that?
[02:28] <Andrew__> Can anyone tell me how openstack serivces that are deployed via juju charms register their hostnames to DNS?
[02:36] <Pinkamena_D> Hmm well I guess I have it, the issue scared me more than I thought. It seems like I just needed to remove some messed up fstab entries, and the emergency mode is no longer a problem
[02:52] <tomreyn> Pinkamena_D: if it scared you, consider reviewing your backup and system / configuration deployment strategies. (glad you found it, though.)
[12:22] <sveinse> What is a good way to disable lvmetad service in 16.04?
[13:59] <jonah> hi does anyone use NUT for their ups? I'm struggling to allow different ips to connect from external networks
[15:38] <Onepamopa> jonah_, whats nut ?
[18:26] <teebeutel> hello guys, someone could help me plz? need informations about ssh
[18:31] <mybalzitch> teebeutel: don't ask to ask, just ask
[18:33] <caliculk> I am trying to upgrade from Ubuntu 14.04 to 16.04 LTS, I did sudo do-release-upgrade, and after running through a majority of the system, I am now stuck with this: http://pastebin.com/RxZue2i0
[18:34] <caliculk> I am now left in a somewhat unusable state, and some of my web-apps are broken (like TT-RSS)
[18:34] <caliculk> Not really looking forward to restarting that server after what has just happened, so I want to be cautious.
[18:35] <tarpman> caliculk: wow, that looks pretty broken :/
[18:36] <caliculk> Yeah, I was really anxious about doing this because every time I do an upgrade like this, it always has a problem.
[18:36] <tarpman> caliculk: are there any logs earlier than what you posted, or is that the beginning of it?
[18:36] <caliculk> This server is remote too, and the people that do have access to it, are not exactly the most technical minded people (ie: parents) so anything I can do to fix it while it is still in a somewhat usable state would be great.
[18:37] <tarpman> caliculk: I am looking at https://bugs.launchpad.net/ubuntu/+source/init-system-helpers/+bug/1572903
[18:37] <caliculk> Well, it terminated the screen session, so I not sure how I can access whatever was on screen prior.
[18:37] <caliculk> Let me pull some /var/log files and put them in pastebin
[18:37] <tarpman> yeah there should be a /var/log/dist-upgrade or something like that
[18:38] <tarpman> I think the next thing I would try is a dpkg --configure --pending and see if it can recover the partial upgrade
[18:41] <caliculk> http://pastebin.com/5gCeypEK
[18:41] <caliculk> When trying to run sudo dpkg --configure --pending: http://pastebin.com/tqiWAX6z
[18:42] <tarpman> oh. gross
[18:43] <tarpman> caliculk: I would agree that rebooting at this time would be a bad idea, btw :p
[18:43] <tarpman> what version of libc6 do you have at this point?
[18:44] <caliculk> 2.23-0ubuntu3 across the board for all versions
[18:44] <caliculk> amd64, i386, -dbg, -dev etc
[18:45] <tarpman> oh, wrong package. I meant to ask about libstdc++6
[18:46] <caliculk> libstdc++6:amd64                                6.1.1-3ubuntu11~14.04.1
[18:46] <caliculk> For both amd64 and i386
[18:48] <tarpman> huh. where'd you get that from? packages.ubuntu.com figures you should have 4.8.4 in trusty and 5.4.0 in xenial
[18:48] <caliculk> No idea. :/
[18:48] <tarpman> I'm beginning to see what happened - 6.1.1 > 5.4.0, so it didn't upgrade that one, but now I guess you still have it exposing the ABI expected by packages in trusty
[18:48] <tarpman> or something like that
[18:49] <tarpman> did you have any PPAs enabled before the upgrade?
[18:49] <caliculk> Probably, I don't recall what they would have been though
[18:49] <tarpman> they should still be in /etc/apt/sources.list. the upgrader might have commented them out
[18:50] <tarpman> you might be able to get moving again by downloading the xenial debs for libstdc++6 and dpkg -i'ing them
[18:50] <caliculk> Everything in the sources.list file is xenial and archive.ubuntu related stuff only.
[18:51] <caliculk> Looking at .save right now
[18:51] <caliculk> But that looks like it is only us.archive.ubuntu.com trusty stuff as well, hno ppas are listed there
[18:51] <tarpman> weird
[18:52] <caliculk> I do remember adding PPAs though, just don't remember what they were
[18:52] <tarpman> er, before trying my suggestion of manually downgrading libstdc++6, better read http://norsoulx.blogspot.ca/2016/08/upgrading-from-ubuntu-1404-to-1604.html
[18:53] <tarpman> probably still doable, but you probably also have to downgrade (or remove) whatever package caused it to get pulled in in the first place
[18:53] <caliculk> Hm, looks like this: libkolabxml1
[18:54] <caliculk> http://pastebin.com/yCVvF84e
[18:55] <caliculk> Is there a way to see a total list of packages that would depend on libkolabxml?
[18:56] <tarpman> without a working apt, not easily
[18:57] <tarpman> maybe dpkg --dry-run --remove libkolabxml1 or such
[18:57] <tarpman> that prints useful results for me without even being root
[19:01] <caliculk> Alright, so running throught that blog post, I am now stuck here: http://pastebin.com/5KepJ6Mk
[19:02] <tarpman> you'll need to install the same version of libstdc++6 for both amd64 and i386
[19:02] <tarpman> both debs in one dpkg -i run
[19:02] <caliculk> Ah
[19:02] <caliculk> Alright, one second
[19:02] <tarpman> (I sure hope I am not leading you into breaking your system)
[19:03] <tarpman> oh yeah, don't forget to dpkg --purge libkolabxml1 later if it turns out it isn't needed any more
[19:04] <caliculk> tarpman, do you happen to have a download link for the i386 version? Can't seem to find it.
[19:04] <caliculk> https://launchpad.net/ubuntu/xenial/+package/libstdc++6 I dont' see i386 listed there
[19:05] <caliculk> Nevermind
[19:05] <tarpman> http://packages.ubuntu.com/xenial-updates/i386/libstdc++6/download
[19:05] <caliculk> I am a doofus
[19:05] <caliculk> Could have changed the path fromt he blogspot post
[19:06] <caliculk> So those installed succesfully...
[19:06] <caliculk> What would be the best recommended action now?
[19:06] <caliculk> :D
[19:07] <caliculk> Cause I think an upgrade would fail, so just do-system-upgrade again?
[19:07] <caliculk> so-release-upgrade*
[19:07] <tarpman> now try the dpkg --configure --pending again
[19:08] <caliculk> Looks like things are going well
[19:08] <caliculk> So far
[19:08] <tarpman> if that goes through, apt-get update and apt-get dist-upgrade, and after all that I think you *should* be able to reboot and carry on
[19:09] <caliculk> Alright, so I will leave that running for now. After that, I will try another do-release-upgrade.
[19:09] <caliculk> Now I just need to figure out why TT-RSS is failing. I assume its a PHP7.0 issue
[19:10] <caliculk> Since it is just serving a plain-text php config
[19:10] <caliculk> $ sudo do-release-upgrade
[19:10] <caliculk> Checking for a new Ubuntu release
[19:10] <caliculk> No new release found
[19:10] <caliculk> Thats a good sign. :
[19:11] <caliculk> )
[19:14] <caliculk_persona> Alright, znc is connected to that server, so...
[19:15] <caliculk_persona> So I have someone on the phone while it is rebooting telling me what is happening, and it said apparmor failed. Which I guess is not normal. :/
[19:16] <caliculk_persona> Alright so the good news is that... it booted back up, it seems...
[19:16] <caliculk_persona> But, KDE is definitely failed for my VNC connection. :(
[19:21] <caliculk_persona> Hm, a bunch of stuff is broken now. Damn
[19:22] <caliculk_persona> But the server is online. So that works though
[19:22] <caliculk_persona> Thanks tarpman
[19:23] <tarpman> caliculk_persona: well, at least now you can ssh in and start fixing things. good luck!
[19:29] <Anonymes> Hi
[20:01] <thekrynn> hi, was looking for a recommendation on server + jbod enclosures for scaling up storage on linux (something that supports SATA drives).
[20:01] <mybalzitch> thekrynn: SE3016
[20:01] <mybalzitch> thekrynn: also supermicro SC847
[20:02] <mybalzitch> I just got a SC847 (45 bay) jbod for $599 from mrrackables
[20:02] <thekrynn> wow, thats cheap
[20:02] <mybalzitch> even included 2 external SAS cables, and an external HBA
[20:02] <thekrynn> reading, thanks!
[20:02] <mybalzitch> np
[20:03] <thekrynn> and im guessing i can hook that guy up to a poweredge with a SAS HBA, no problem?
[20:05] <mybalzitch> so long as it physically supports the card
[20:05] <mybalzitch> ie: is a pci-e slot, and takes half height/full height cards
[20:06] <mybalzitch> and yeah, the mrrackables stuff comes with a SAS HBA, so its a hell of a packaged deal
[21:13] <caliculk> Alright, one last thing...
[21:13] <caliculk> So now when I reboot the server, instead of it going straight to KDE graphical desktop login, it boots to the normal tty console login screen.
[21:13] <caliculk> Is there anyw ay to verify that my KDE installation is setup properly? Because our VNC server is just displaying a gray screen and than KDE5 crashes shortly after.
[21:13] <caliculk> Or is that better suited for #kubuntu?
[22:08] <Gorian> successfully installed Ubuntui 16.10 on top of a ZFS root using a bash script :)
[22:10] <FManTropyx> yay
[22:10] <Gorian> yus!
[22:12] <Gorian> so
[22:12] <Gorian> my server says it's using 2Gbs, but htop, and ps say all processes are using 0.0% of memory?
[22:12] <FManTropyx> wow, you have invented a zero-memory-usage system!
[22:13] <Gorian> right?
[22:13] <Gorian> I would assume they are just using such a small amount it's not listing it?
[22:13] <Gorian> but really, seems odd....
[22:14] <FManTropyx> sounds like an error, but I dunno
[22:14] <Gorian> eh, I'll try rebooting, see if it persists
[22:17] <trippeh> Gorian: sure its just not cache?
[22:18] <Gorian> I don't think so? Might ben, but htop treats cache different than in-use memory I thought. I could be wrong
[22:19] <tomreyn> vmstat -w
[22:25] <Gorian> vmstat?
[22:25] <Gorian> and rebooted, and it's fine, using 645m, so that's a bit more in line with what I expected
