pvmove freezes system
This document (7004393) is provided subject to the disclaimer at the end of this document.
The command output might look like:
# pvmove /dev/sda6 /dev/sda7
system-pvmove0: device not found:
/dev/sda6: Moved: 1.0%
/dev/sda6: Moved: 1.8%
/dev/sda6: Moved: 2.7%
/dev/sda6: Moved: 3.5%
/dev/sda6: Moved: 4.4%
/dev/sda6: Moved: 5.2%
/dev/sda6: Moved: 6.1%
/dev/sda6: Moved: 6.9%
Then make sure that "/var" and(or) "/var/run" are not stored on the PV devices which are involved in the 'pvmove' command, that is, the related Logical Volumes (LV) are not mounted under "/var" or "/var/run".
In fact 'pvmove' suspends all related dm table of logical volumes before it starts working, and as "/var" or "/var/run" are accessed during execution of this process, this leads to a deadlock.
If "/var" or "/var/run" have to be moved, it is recommended to boot into live CD first.
