Hi,
I am having some trouble doing pvmove.
I did reduce the fs and resize the lv with these commands:
e2fsck -f /dev/mapper/vg00-data && resize2fs /dev/mapper/vg00-data
551000
lvresize -L 552000M /dev/vg00/data
So now pvdisplay says something like:
part total free alloc
hdb1 1786 0 1786
hde1 1786 0 1786
hdf1 1786 0 1786
hdg1 2680 0 2680
hdh1 1190 603 587
sda1 3724 3724 0
Since I want to remove hdb1 and hde1 I tried to pvmove hdb1 with:
pvmove /dev/hdb1
My output follows:
thor:~# pvmove /dev/hdb1
Can't expand LV: Mirror support missing from kernel?
ABORTING: Temporary mirror activation failed. Run pvmove --abort.
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'vg00-pvmove0'.
thor:~# pvmove --abort
Can't expand LV: Mirror support missing from kernel?
Suspension of temporary mirror LV failed
Can't expand LV: Mirror support missing from kernel?
I am running a clean 2.6.7-kernel, with device mapper, dm-crypt and raid
(including all raidlevels) as modules, the only thing I do not have
under RAID and LVM is Multipath I/O support.
Can anyone please tell me why I am getting this problem and how to solve
it?
Do CC me, I am not subscribed to the list.
Thanks in advance
