Title: LVM trouble
Post by: Ztoragefool on November 16, 2010, 10:33:07 AM

is there any magic involved to see lvm drives after rebooting? (TCL 3.2 64bit)

on creation, it appears as
 /dev/dm-0
 /dev/mapper/vg2-test -> ../dm-0
 /dev/vg2/test -> ../dm-0

but it´s gone after rebooting...

You need to add the following line to /opt/bootlocal.sh and do a backup.
vgchange -ay

wowhowhooohohow...

bug? i just lost my volume.

atm i am playing around with qemu. starting my instance again, qemu complained one disk given did not exist. and qemu was right:

out of the sudden, my /dev/mapper contains nothing more than the control device. the symlinks are gone. but the /dev/dm-X devices they have shown at still exist.

ok, no prob, can handle this and reboot. but such things must not happen. so...

question: anyone wants to take the chance and investigate this further? any logs needed? dmesg and 3 files in /log/var do not show anything, so i´ve got nothing to post, but i need a coffe break anyway, so reboot can wait    8)
