I think I've just fucked up my LVM device... I have three 500Gb disks and have now bought a new 1.5Tb that I was going to move all the data from the three to and then retire the three 500Gb disks... I've done this exact same thing succesfully before.. I started the pvmove yesterday (on disk 1). Then the machine crashed... Booted it up again and ran the pvmove again. It (pvmove) said that there's already a pvmove running. The command I just ran is counting up from 0.0% up to 100% (even though it was about finished when it crashed). This move took about 15h... Then this shows up: ----- s n i p ----- [...] /dev/md7: Moved: 99,9% /dev/md7: Moved: 100,0% /dev/md7: Moved: 100,0% WARNING: Volume group movies is not consistent ABORTING: Can't find mirror LV in movies for /dev/md7 celia:~# pvmove /dev/md7 /dev/md9 No data to move for movies celia:~# vgreduce -v movies /dev/md7 Finding volume group "movies" Using physical volume(s) on command line Archiving volume group "movies" metadata (seqno 85).
