hi all,
i try to explain the problem i have here,
it looks like dataloss to me because is cannot set the
volumegroup online anymore.
what i had originally:
1 fibre channel diskdrive of the size 236.02 GB.
i had created one both pv's and assigned it
to a volume group called tivg1.
i made 1 lv out of it, using the maximum possible
PE's available (PE size = 16 MB). i named this lv
/dev/tivg1/tilv1.
now i added 3 new drives to this vg, 1*16.85 GB
and 2* 8.43 GB.
i created a new lv /dev/tivg1/tilv2, using again
the max. number of free pe's, resulting in a lv size
of 33.64 GB.
both lv's have been in production with no problem.
until one 8.43 GB drive (/dev/sdv1 used in /dev/tivg1/tilv2)
got corrupted somehow.
/dev/tivg1/tilv2 crashed but /dev/tivg1/tilv1 kept running with
no problems.
until i rebooted.
the problem is that i now cannot reactivate tivg1 anymore
and get to my data which relies on /dev/tivg1/tilv1.
even though in know that this drive (/dev/sdg1) is 100%
running and ok.
i already re-formated the corrupted 8.43 GB drive and tried to
to vgcfgrestore the old lvm-config to the drive.
but i still cant get the vg online again.
at this point all data on the 236.02 GB lv seemes to be lost.
can anybody help with any ideas?
best regards,
tomasz
