Environment

SUSE Linux Enterprise Server 10 Service Pack 4
Novell Open Enterprise Server 2 (OES 2) Linux Support Pack 3

Situation

File system hangs and command does not return the prompt when executing pvmove.

Resolution

The issue is due to a bug in the new code which suspends the device but does not resume it. An interim solution is to resume the device manually using dmsetup:

# dmsetup resume device_name

Where device_name is meant to be the filename under /dev/mapper.

Additional Information

This happens specifically with version lvm2-2.02.17-7.36.1 which is provided with patch slesp4-lvm2-7916 of January 13th 2012.

The bug has already been reported to engineering and a temporary fix is available. For further information please open a Service Request and mention this TID.
