[Bug 76421] Re: system crash when creating more than one snapshot of a lvm volume

I was not able to reproduce this with 2.6.15-23-server. Perhaps you could post a script that reproduces the error along with the specific kernel / lvm versions installed. It could also be an load related issue like this one https://launchpad.net/ubuntu/+source/linux-source-2.6.15/+bug/71567 (no on

I've reproduced this panic with a virgin (kernel.org) 2.6.15.7 (I reused the ubuntu 2.6.15-23-server config with make oldconfig). I could NOT reproduce the panic with 2.6.19.1. So logically methinks something was fixed along the way. Any pointers for what to do next? Anyone want to lend a hand in

2006-12-05 Thread acutler
True however, ViewCVS has now been renamed ViewVC which nicely reflects that it is no longer just for CVS. So going forward is there a way to install the CVS or Subversion components depending on whether svn or cvs is installed? Or perhaps ask the user? I think in any case I should file a bug repo

Hi Ben, I've been able to reproduce this on three different machines including one machine I specially prepared for testing. This bug is reproducible without vmware being installed. If you install dapper with one PV, VG vg_sys and one lv lv_vmware (ext3) then you should be able to run my crash.sh

I can reproduce this too with 2.6.15-26-386 #1 PREEMPT. Recovery is simple, the device mapped just gets all out of sync. Rejig the devices and remove the snapshot and reboot. eg: mv /dev/mapper/vg_sys-lv_vmware /dev/mapper/vg_sys-lv_vmware_snap ; mv /dev/mapper/vg_sys-lv_vmware-real /dev/mapper/v

This is 100% reproducible for us. It seems that lvremove is not syncing before removal of the snapshot. (or perhaps it is wrong to --force removal of snapshot.) Calling 'sync' immediately before removing the snapshot seems to mitigate the chance of a crash. Tested with Ubuntu 6.06.1 i386, clean in
