[opensuse] unbootable system after lvm snapshot
hi all, This issue is really about sles9. Please point me to the right list is there is one... Anyway, I have found the following serious issue on sles9, sp3, fully up to date: After a powercut machines with LVM partitions formatted with ReiserFS with an active snapshot do not boot properly anymore. To reproduce: - stock sles9 sp3 install - create lvm partition - create a logical volume formatted with reiserfs and mount it - copy some data to it - enter "modprobe dm_snapshot" to load snapshot kernel module (why doesn't this happen automatically??) - create an lvm snapshot and mount it Cut the power (pull out the plug) and your system will no longer boot. Solve this situation by manually removing the snapshot ("lvremove /dev/system/snapshot-name") even though at that point the directory /dev/system does not even exist, and reboot. Tested on two different machines, and found it out the hard way on our production mailserver... I've tried this using xfs as well, and that has no problems. Is this a bug in lvm, reiserfs or the kernel? (or am I doing something wrong here..?) Strange: xfs has no problem, and SuSE default (reiserfs) does NOT work...
