Bug#582108: lvm2: lvcreate fails with: device-mapper: reload ioctl failed: Invalid argument

[Igors Jansons]

Package: lvm2
Version: 2.02.39-7
Severity: normal

I was using LVM2 on XEN server for some time now and recently lvcreate
command started to
fail with an error like this:

# lvcreate -L20G vg -ntest
  device-mapper: reload ioctl failed: Invalid argument
  Aborting. Failed to activate new LV to wipe the start of it.
  LV vg/test in use: not deactivating
  Unable to deactivate failed new LV. Manual intervention required.

Output from syslog:

device-mapper: table: device 8:7 too small for target
device-mapper: table: 254:6: linear: dm-linear: Device lookup failed
device-mapper: ioctl: error adding target to table

What i found out is lvcreate actually successfully creates LV only if
it 7Gb or smaller
which is weird because there is plenty of space left. Also lvcreate
creates device file
in /dev/mapper directory and the volume shows up in lvs and lvscan
output but is unusable.
Ive tried using vgmknodes command as #293693 bug report suggests but
it didnt help either.
