I created a volume group "m73304raid_vg1" with 2 physical volumes "/dev/sda"
and "/dev/sdc" .
I then created 2 logical volumes "/dev/m73304raid_vg1/raid_lv1" occupying
"/dev/m73304raid_vg1/raid_lv2" occupying /dev/sdc. formated the volumes
with linux "ext3" file
system and stored some data on the volumes.
One of the scsi devices where getting errors and hung up the system. Now I
can't get the system
to mount the volumes:
I am running RedHat Enterprise Linux 3.0 (u3), but created the volumes under
(u1). I upgraded
to u3 to solve scsi issue, but started having problems with lvm under u1.
vgscan only found 0 of 4095 LEs for LV /dev/m73304raid_vg1/raid_lv2 , and
there are no reports of
vgscan ERROR "vg_read_with_pv_and_lv(): allocated LE of LV can't
get data of volume group
"m73304raid_vg1" from physical volumes(s)
vgchange -a y /dev/m73304raid_vg1 , reoprts
volume group "m73304rai_vg1" does not exist.
inactive PV "dev/sda" is assoceated with unknown VG "m73304raid_vg1"
inactive PV "dev/sdc" is assoceated with unknown VG "m73304raid_vg1"
vgcfgrestore -n m73304raid_vg1 -v -l -l --test
shows all the right information about the original VG, LV and PV but
vgcfgrestore -n m73304raid_vg1 -v /dev/sda /dev/sdc
reports: -- usage information
please enter physical volume name
can anybody help me recover my data?
