Subject: Disc crash when
using LVM...
I'm desperate... please help...
First of all I'm rather new to this LVM business,
but I managed to get a three disc LVM up and running, but now everything is
chaos. One disc just crashed and I can't retrieve any of the information
from the 2 remaining discs, please help me retrieve my data. Yes, it was an
IBM drive, but it was of a rather new model (80GB) and not much used, so I was
rather astonished about the crash.
I have read about another guy who also
experienced a disc crash (IBM) and he solved it by replacing the faulty drive
with another one, but he didn't mention how he managed to get it up and
running again. Did he use a replacement drive of the same size? What commands
did he have to use in order to get it up and running again?
I've been searching for hours to find any
relevant information about what to do in order to retrieve the remaining data
from my other drives. I'm not good at this so I really don't want to issue any
commands that will delete my remaining data permanently.
Here's how it looks like now:
>pvscan
pvscan -- reading all physical volumes (this may
take a while...)
pvscan -- inactive PV "/dev/hdd1" is associated to
unknown VG "vg01" (run vgscan)
pvscan -- inactive PV "/dev/hda8" is
associated to unknown VG "vg01" (run vgscan)
pvscan -- total: 2 [139.70 GB]
/ in use: 2 [139.70 GB] / in no VG: 0 [0]
>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 "vg01" 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
>lvscan
lvscan -- no volume groups found
I have no idea what has happened to my volume
group, it seems like it has disappeared. All I can do is scan for the physical
volumes.
What to do next?? I'm still searching for
information relevant to the problem, but please give me a hint or
two...
