Package: lvm2
Version: 2.02.06-2
Severity: critical
Justification: breaks the whole system
I have twice now attempted a pvmove in order to clear one of my disks. The
same failure has occured twice.
once pvmove has failed, any subsequent attempt at access to logical volumes
involved in the move in the
volume group effected hangs the process and htop shows it to be in
interruptable sleep mode. As a result it
cannot be killed. This includes a shutdown hanging the machine, which
ultimately means a hard reset.
Upon reboot, the effected lv(s) fail to mount, but the boot process goes ahead
anyway, leaving the system writing
new data into the parent directory mount point, ultimately making recovery of
all data a very tricky process.
Effectively the only approach is to boot into single user mode and then do a
pvmove --abort
Here is the output from the pvmove with the first act that causes the problem.
In my case the three lv's that have
extents to move are the ones that fail to mount on re-boot. Note also the
lvdisplay following this failure has hung,
as has a pvmove --abort from another terminal.
