Hi,
I've got a 2.6.18-rc5-mm1 kernel on an Dual processor Xeon 550mhz
system running Debian unstable, updated today. I've got a pair of
120gb disks mirrored using md, setup so that the single partition
on the disks is /dev/md0. I've got a PV setup on there, with a couple
of LVs, which then have ext3 filesystems on them, mounted as /home and
/local respectively.
I just removed another LV which I didn't need anymore of around 25G in
size. I'd like to now lvextend one of my two remaining LVs to then
beable to re-size the ext3 filesystem for more space. But I get:
# lvextend -v -L +1g /dev/data_vg/home_lv
Finding volume group data_vg
Archiving volume group "data_vg" metadata (seqno 16).
Extending logical volume home_lv to 52.00 GB
Creating volume group backup "/etc/lvm/backup/data_vg" (seqno 17).
Found volume group "data_vg"
Found volume group "data_vg"
Loading data_vg-home_lv table

In my dmesg log I'm seeing the following:
device-mapper: table: 253:0: linear: dm-linear: Device lookup failed

Any hints on what I need to do here? I can create a test LV (as shown
above) but I can't extend either LV which already exists.
Thanks,
John
