Hi!
I'm really sorry to bother you, but I'm desperate
and I don't know any more to do in order to get my LVM partitions back up
again.
I have a machine with three discs and together they
formed one 226GB large partition using LVM. One of those discs crashed and
the data is unrecoverable, leaving me with two discs which still contains data,
but how do I extract the data?? I'm using reiserfs since it was the only
filesystem which could be resized on the fly as I understood it. Somehow the
volume group vg01 is nowhere to find any more after the crash, but I can still
do a pvscan and see that the discs are intact.
Please give me some hints here. I have searched and
searched for information and I can't find anything applicable in my case. I
really need to get to the data that's still there hidden... no backup is made
due to another problem. :-(
Disc number one with still intact
information.
--- Physical volume ---
PV Name /dev/hda8 VG Name vg01 PV Size 24.66 GB [51710337 secs] / NOT usable 4.19 MB [LVM: 152 KB] PV# 1 PV Status NOT available Allocatable yes (but full) Cur LV 1 PE Size (KByte) 4096 Total PE 6311 Free PE 0 Allocated PE 6311 PV UUID 13x8k8-ZCFk-aQib-FJXh-mDMj-QtG5-Xsfn4X Disc number two with still intact
information.

drive just to see if it had any effect, but no...

/etc/lvmtab.d directory
The device /dev/vg01.... is also gone
but I think it was there earlier after the crash, but I have tried several ways
of getting the info back so it might have been removed by issuing any of the
commands??
Thanks a bunch for any hints or directions in
order to get the information back...
