OK Chaps I've broken it.
I have a VG containing one LV and made up of 3 live disks and 2 failed disks.
Whilst the disks were failing I attempted to move date off the failing
disks, which failed so I now have a pvmove0 that won't go away either.
So if I attempt to even remove a live disk I get an error.
[root@nas ~]# vgreduce -v vg_backup /dev/sdi1
Using physical volume(s) on command line.
Wiping cache of LVM-capable devices
Wiping internal VG cache
Couldn't find device with uuid eFMoUW-6Ml5-fTyn-E2cT-sFXu-kYla-MmiAUV.
Couldn't find device with uuid LxXhsb-Mgag-ESXZ-fPP6-52dE-iNp2-uKdLwu.
There are 2 physical volumes missing.
Cannot change VG vg_backup while PVs are missing.
Consider vgreduce --removemissing.
There are 2 physical volumes missing.
Cannot process volume group vg_backup
Failed to find physical volume "/dev/sdi1".
Then if I attempt a vgreduce --removemissing I get
[root@nas ~]# vgreduce --removemissing vg_backup
Couldn't find device with uuid eFMoUW-6Ml5-fTyn-E2cT-sFXu-kYla-MmiAUV.
Couldn't find device with uuid LxXhsb-Mgag-ESXZ-fPP6-52dE-iNp2-uKdLwu.
WARNING: Partial LV lv_backup needs to be repaired or removed.
WARNING: Partial LV pvmove0 needs to be repaired or removed.
There are still partial LVs in VG vg_backup.
To remove them unconditionally use: vgreduce --removemissing --force.
Proceeding to remove empty missing PVs.
So I try force
[root@nas ~]# vgreduce --removemissing --force vg_backup
Couldn't find device with uuid eFMoUW-6Ml5-fTyn-E2cT-sFXu-kYla-MmiAUV.
Couldn't find device with uuid LxXhsb-Mgag-ESXZ-fPP6-52dE-iNp2-uKdLwu.
Removing partial LV lv_backup.
Can't remove locked LV lv_backup.
So no go.
If I try lvremove pvmove0
[root@nas ~]# lvremove -v pvmove0
Using logical volume(s) on command line.
VG name on command line not found in list of VGs: pvmove0
Wiping cache of LVM-capable devices
Volume group "pvmove0" not found
Cannot process volume group pvmove0
So Heeelp I seem to be caught in some kind of loop.
