What interests me here is that the lvm-1.0.1rc4(ish) seems to be more robust
then lvm-1.0.1 when dealing with a failed LV creation.
What seems to happen is that the snapshot is partially registered in the
kernel. The snapshot appears in the "/proc/lvm/global" as well as in the
"/proc/lvm/VGs/HDA/LVs/". However, "/dev/HDA/SNAP" is missing and I can
generate it by doing a vgscan and a lvscan. However, this does not fix the
kernel from dying upon a reboot.
The only way I have found to recover from this situation is to use an old
kernel that has only lvm-1.0.1rc4(ish) - this kernel does not Oops upon boot
and fixes the failed snapshot so that either it can be used later or removed
correctly.
The procedure goes something like this:
1) create snapshot on an XFS partition - it fails with an Oops.
at this point I can not view or remove the failed snapshot although it
appears in the correct places in /proc. The /dev/vg/lv entries are missing.
2) During the startup after a boot the machine dies after multiple Oopses and
dies finally with a Kernel panic. The kdb ouput from the start-up is
appended below.
3) Reboot using an old kernel with lvm-1.0.1rc4(ish) and everything starts
fine. You can then lvremove without a problem.
4) I can then reboot into a kernel that has been upgraded to lvm-1.0.1
without a problem.
The system is based on a minimal install of RH7.2 using a SGI XFS CVS kernel.
2.4.17-xfs
+ lvm-1.0.1 upgrade (from LVM CVS)
+ VFS-lock patch
Is there any other info people need?
Once the XFS snapshot creation has failed this is what happens during the boot
process after the reboot.
