[linux-lvm] LVM Down After Disk Failure

[Sebastian Walter]

Dear list,

after a power failure we had troubles with a hard drive, it went down
unrecoverably. So I removed the LV's wich had PE's on this disk by
executing, and I got this error:

[root at xxx root]# lvremove /dev/xxx/data5
lvremove -- do you really want to remove "/dev/vghrsc/data5"? [y/n]: y
lvremove -- ERROR "vg_write(): write" storing data of volume group
"vghrsc" on disks

then I got another strange error:

Message from syslogd at xxx at Mon Apr  3 12:14:39 2006 ...
xxx kernel: journal commit I/O error

therefore I decided to reboot the system. After the reboot, I couldn't
manage to get the system up and running again, I got error messages
about vgchange not finding any VG's.

I even ran vgcfgrestore, but it succeeded without giving me a hint about
errors.

vgscan now gives me:

[root at xxx root]# vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- ERROR "vg_read_with_pv_and_lv(): current PV" can't get data of
volume group "vghrsc" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group

pvscan gives me (I had to remove the scsi disk, before I got some sense
key errors here):

[root at mex root]# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/sdb1"  is associated to unknown VG "vghrsc"
(run vgscan)
pvscan -- inactive PV "/dev/sdc1"  is associated to unknown VG "vghrsc"
(run vgscan)
pvscan -- inactive PV "/dev/sdd1"  is associated to unknown VG "vghrsc"
(run vgscan)
pvscan -- inactive PV "/dev/sde1"  is associated to unknown VG "vghrsc"
(run vgscan)
pvscan -- inactive PV "/dev/sdf1"  is associated to unknown VG "vghrsc"
(run vgscan)
pvscan -- total: 5 [6.84 TB] / in use: 5 [6.84 TB] / in no VG: 0 [0]

/dev/sdf1 is the scsi drive I removed in the meanwhile and which is not
present anymore.

I would really appreciate any help! Thanks in advance,
Sebastian
