[gentoo-user] recover from disk crash lvm2 group

2008-08-02 Thread Eray Aslan
Hello,

One of the disks in a 3-disk lvm2 group crashed.  I would like to
continue with the remaining 2 disks.  How to remove the non-functioning
disk from the group and re-create the volume with 2 disks?  I have backups.

# vgremove home_vol
  Couldn't find device with uuid 'D0HvzD-Vw9B-40Vd-NSn1-RW0d-SlVF-pM4jOH'.
  Couldn't find all physical volumes for volume group home_vol.

The lvm(8) man page lists the --partial flag.  A quick Google search
reveals:

vgchange -ay --partial

-a

Grr, it does indeed.  For the archives, also had to use vgreduce with
--removemissing flag.

Sorry and thank you for the quick response.
