Hi
I am trying to remove an old physical disc from my logical volume.
I have had earlier problems, as discussed in recent days on the lvm
mailing list, but it is now suggested that I post here.
The LV has sufficient free PEs on it, but pvmove is not working because
of device-mapper errors.
I have added a temporary usb external hard drive as it appears that
pvmove needs to create a mirror lv temporarily. I do not want to use
this drive in this volgroup long-term.
# pvscan
PV /dev/sdb2 VG VolGroup00 lvm2 [27.75 GB / 960.00 MB free]
PV /dev/sda2 VG VolGroup00 lvm2 [314.97 GB / 30.84 GB free]
PV /dev/sdd3 VG VolGroup00 lvm2 [52.50 GB / 52.50 GB free]
Total: 3 [395.22 GB] / in use: 3 [395.22 GB] / in no VG: 0 [0 ]
I am posting here because of the slightly cryptic errors apparently
being generated by device-mapper. The second error is almost certainly a
consequence of the first, but the first one has left me stumped.
Thanks for your help
Nick
