[Bug 1265921] [NEW] bacula-traymonitor fails to launch
Public bug reported: after creating a config file and verifying with bacula-traymonitor -t, launching bacula-traymonitor produces no GUI. I'm guessing it goes to the tray, but Unity doens't have a tray. Ideally it would go to the indicator area like indicator-multiload does. but an acceptable workaround would be to just display the GUI and then exit on close, like a normal application. an optional flag to do this would be fine if detecting a tray is unreliable..

[Bug 1057054] [NEW] poor performance after upgrade to Precise
Public bug reported: I had a Lucid x64 server working with a Dell MD3000i with 4 paths and worked as expected. I added the prio rdac line to the conf file, then upgraded to Precise, and removed the old mpath_rdac line and reboot one more time, just to be sure. I did this based on a section in https://help.ubuntu.com/12.04/serverguide/serverguide.pdf as a sanity check test, I'm doing 'pv /dev/mapper/dellsas1 /dev/null' (friendly names enabled). On Lucid i'd get about 100MB/s After upgrading to Precise I get an almost solid 768kB/s. If I instead use the 4 underlying /dev/sd* devices, 2 give errors as expected, and 2 run at about 100MB/s as expected so iscsi seems to be working correctly and multipath not. ** Affects: multipath-tools (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1057054 Title: poor performance after upgrade to Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1057054/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

via lsmod? scsi_dh_rdac is loaded. Does it need to be in the initramfs even if I'm not booting off it? doing so does fix the performance, but it is also counter-intuitive. Shouldn't the multipath driver read the conf file and load the needed modules before finding anything? -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1057054 Title: poor performance after upgrade to Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1057054/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1057054] Re: poor performance after upgrade to Precise
My devices are on iscsi, and I'm not booting off them. They are not connected until after the root goes live and network comes active, via normal means. I never manually loaded scsi_dh_rdac before, it's not in my initrd nor my modules files. It loaded automatically somehow. Why isn't it loading automatically earlier? What loaded it if multipath driver didn't? other drivers load child drivers, why can't multipath? I never found that html server guide in my searching and it is helpful. The PDF I only found after failing a couple times. Other software presents prompts and links when config formats change, or even changes them for you, it's become expected, multipath should do it too. The local manpage for multipath.conf still has prio_callout and not prio documented, and has zero mention of having to manually load drivers. Whether this a bug in how the drivers get loaded, or how the documentation is presented, or how upgrade transition is handled isn't that relevant, it's still a bug. It's Lucid to Precise upgrade regression bug. it's not smooth and it's not even easy to find why it's failing. If the upgrade had presented me with a screen saying the config and driver loading formats have changed, and that html link, I'd have figured it out and we wouldn't be here. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1057054 Title: poor performance after upgrade to Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1057054/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 1057054] Re: poor performance after upgrade to Precise
But it survive a reboot. several in fact. I always reboot after major config changes to reduce the chance of a 2am phone call after a power outage. I don't lightly file bugs, it's 3 days and 4 OS re-installs to get me here. This was working on Lucid, and required additional setup for Precise and I found documentation difficult to find. It's repeatable, I've been repeating it all week, both on upgrades and clean installs. Did lucid also use scsi_dh_rdac? I had no issues there. Something changed. I wish i could help find out what.

[Bug 1057054] Re: poor performance after upgrade to Precise
after the upgrade and initial reboot, I change the config file and verified multipath -ll was as I expected, then rebooted and did the pv test. I did nothing else between my first posting and the reply verifying lsmod, so yes, it was loaded on reboot. I have both controllers in the md3000i, and each has 2 ports. a LUN can be on either controller, and active/active on that one controller, with the other controller as standby. I also have luns on it used by esxi, and the RR paths appear to be the same. I did not check which driver got loaded on lucid, and the dell docs are really kinda all over the place so I was trying to ignore them. rdac did seem to be what was happening based on how multipath -ll showed things, and I did see roughly equal traffic on 2 nics. In my first attempt with Precise I did initially see the ping-ponging you mention, before I understood how to apply rdac configs. With Lucid I put the rdac config in right from the start and did not see that behavior. is it possible the old mpath_prio_rdac callout was loading the driver early in the process? I was not aware of scsi_dh_rdac's existence until this thread, so I have no explanation of how it's getting loaded when you think it shouldn't be. it's nice to see the config codified, I'll have to experiment with that some. thanks for that info. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1057054 Title: poor performance after upgrade to Precise To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1057054/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 524450] Re: smbd panic using root postexec
You'll need some cd iso's in a directory, then see my samba.conf for how i create the shares. the share names should match the iso file name but add a iso- prefix. the mount and unmount scripts will handle creating the share directories and loop mounting and unmounting the iso files to it I've not tried it on a different 9.04 or 9.10 yet though and I suspect i may have a different problem. I decided to go production with this server anyway, and I have an old application that runs on NT4 IIS that uses an IIS virtual directory to a UNC path that is just a normal samba share, no pre/post-exec's, on this server and it too is panicing smbd in exactly the same way. No other shares or clients are causing panics. the behavior is a little different, the share still works initially but seems to call the panic action quite often, possibly when IIS decides the share is idle and disconnects it, and it will usually reconnect on the next access, but so far once a day it will not reconnect requiring a restart of the IIS admin service. This setup has been working perfectly (as far as I know) for many years, starting with samba 2.4.x on Debian Sarge and with various Ubuntu and samba versions since. The common factor it seem is when windows disconnects from a share without a full system logoff or shutdown. Is there a way to increase logging for just a single share to get more data? I have 50 clients PC's on this now so a system wide log level increase will make a hell of a lot of noise. -- smbd panic using root postexec https://bugs.launchpad.net/bugs/524450 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to samba in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

I'm not sure what you mean, can you be more specific? it's a bone stock ubuntu install dist-upgraded to 8.04 from a fully working 7.10. I restored my disk image backup to re-upgrade and it's working again, so it's something that changed in the ubuntu packages between 7.10 and 8.04 since nothing else has changed on my server. the code that triggers this is simply a call to mssql, and only on certain queries. I have nearly 100 calls that work and about 5 that don't, and there is nothing especially different about the ones that don't work. in fact the more complex ones with large resultsets and multiple resultsets DO work and these small single table 5 row results fail while other similar ones do not fail. 7.10 works + 8.04 fails == regression bug in something, somewhere. -- ALERT - canary mismatch on efree() - heap overflow detected https://bugs.launchpad.net/bugs/294179 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to php5 in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
