I've a LVM one physical volume "vg0" that created on 10 RAID devices. It worked still the day. But one day, I have problem about vgscan reports that it can't find my VG. My VG structure was this. | /dev/md1,md2,md3,md4,md5,md6,md7,md8,md9,md10 => vg0 But md10 was broken. I need to restruct VG like this. | /dev/md1,md2,md3,md4,md5,md6,md7,md8,md9 => vg0 But vgscan is can't find VG |vgscan |vgscan -- reading all physical volumes (this may take a while...) |vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created |vgscan -- WARNING: This program does not do a VGDA backup of your volume group I tried uuid_fixer. but I get only error. |uuid_fixer /dev/md1 /dev/md2 /dev/md3 /dev/md4 /dev/md5 /dev/md6 /dev/md7 /dev/md8 /dev/md9 |Error: number of PVs passed in does not match number of PVs in /dev/md2's VG | 9 PVs were passed in and 10 were expected. I tried pvmove... |pvmove --force -v /dev/md9 /dev/md10 |pvmove -- checking name of source physical volume "/dev/md9" |pvmove -- locking logical volume manager |pvmove -- reading data of source physical volume from "/dev/md9" |pvmove -- checking volume group existence |pvmove -- ERROR: can't move physical extents: volume group vg0 doesn't exist How do I carry out the restructuring of it and can I reconstruct it?
