[linux-lvm] more snapshot probs



Hi

I've applied the recommended patches to 2.4.7 - beta8, VFS lock, and patch
in previous emails.

Now, when I create a snapshot LV:

lvcreate -s -L500 -nsnap /dev/vg00/lvol6
(where /dev/vg00/lvol6 is 3GB striped across 2 PVs)

I get these 2 messages in my logs a few seconds later:

Jul 28 15:10:05 greebo kernel: lvm -- _pv_get_number failed for rdev = 0
Jul 28 15:10:05 greebo kernel: lvm -- giving up to snapshot
/dev/vg00/lvol6 on /dev/vg00/snap: couldn't prepare kiovec blocks (start
probably isn't block aligned)

THen when I try to mount:

[root greebo /root]# mount /dev/vg00/snap /mnt/homesnap/
/dev/vg00/snap: Input/output error
mount: permission denied

And in the log:

Jul 28 15:13:28 greebo kernel: lvm - lvm_map: ll_rw_blk for inactive LV
/dev/vg00/snap

Any ideas?

Cheers!

James
