hi,
after using for some time lvm without any problems, my lvm system
generates after rebooting some strang errors.
the problems look like these:
http://www.copilotconsulting.com/mail-archives/linux-lvm.2005/msg00025.html
but the solution doesnt work for me.
summery:
system suse 10.1, boot drive sata /dev/sda (no lvm)
lvm composed of 8 ide drives (/dev/hda to /dev/hdh)
worked for some time, but i think the auto-update of suse screwed the
lvm.
pvscan, pvdisplay, lvsvan and vgscan all generate errors. i have no idea
where the "logic extend" is already mapped. i cant diagnose the error.
i think the pv are still intact, but i dont knwo how to put em back
together.
here are some of the errors:
tokyoo:/tmp # pvscan
/dev/sdb: open failed: Kein Medium gefunden (No Media found)
/dev/sdc: open failed: Kein Medium gefunden
/dev/sdd: open failed: Kein Medium gefunden
/dev/sde: open failed: Kein Medium gefunden
logical extent (630) already mapped.
Couldn't fill logical volume maps.
logical extent (630) already mapped.
Couldn't fill logical volume maps.
No matching physical volumes found
tokyoo:/tmp # pvdisplay
logical extent (630) already mapped.
Couldn't fill logical volume maps.
logical extent (630) already mapped.
Couldn't fill logical volume maps.
remark: with every commad that generates an error i get the "No Media
found" error block für the /dev/sdx devices. i removed them to save
space.
but strangely the single drives are recognised as proper PV:
tokyoo:/tmp # pvdisplay /dev/hda1
--- Physical volume ---
PV Name /dev/hda1
VG Name system
PV Size 111,78 GB / not usable 0
Allocatable yes
PE Size (KByte) 16384
Total PE 7154
Free PE 7154
Allocated PE 0
PV UUID afdGTQ-95Qv-f3oL-anWh-V2LO-PKIf-eXTbRb
[...]
