Title:
lvextend segfault on logical volume extend
Status in lvm2 - Logical Volume Manager:
Fix Released
Status in “lvm2” package in Ubuntu:
New
Bug description:
Binary package hint: lvm2
My system is running 2.6.31-20-generic #57-Ubuntu SMP AMD64 (current
karmic-proposed).
Below is the series of commands executed on my logical volumes, two of
them currently open were extended 20GB (prior to file system resize),
and then I wanted to consume the remaining extends on one of them.
Prior to executing these commands I removed two other existing volumes
in the same group order to free up the space.
My pv's sit on top of a RAID1 md device as shown below, similar to a
debian report here: http://bugs.debian.org/561931
From dpkg:
ii lvm2 2.02.39-0ubuntu11
From dmesg:
