Package: lvm2
Severity: critical
Justification: breaks the whole system
I unwittingly ran into bug #288354 today. Creating the snapshot froze my
machine, as described in that bug report.
After a while I rebooted the machine, but it will no longer boot up:
device-mapper: 4.1.0-ioctl (2003-12-10) initialised: [EMAIL PROTECTED]
Can't expand LV: Snapshot support missing from kernel?
2 logical volume(s) in volume group "main" now active
pivot_root: No sKernel panic: Attempted to kill init!
uch file or dire ctory
/sbin/init: 432: cannot open dev/console: No such file
I booted into a recovery system and the various filesystems and volumes
seemed fine:
rescue:~# lvdisplay

However, when I try to remove the rootbackup snapshot:
rescue:~# lvremove -v /dev/main/rootbackup
Using logical volume(s) on command line
Do you really want to remove active logical volume "rootbackup"? [y/n]:
y
Archiving volume group "main" metadata.
Found volume group "main"
Loading main-root-real
Loading main-rootbackup-cow
Loading main-rootbackup
At this point, the machine crashes as before. I can still ping it, but
user space seems totally dead.
