Re: [linux-lvm] LVM1 problem, exported volumegroup with one deaddrive (fwd)



Hi Melinda,

Yes I tried using LVM2 very early since it was said it could cope with
disks that were inaccesible. However the vgreduce --removemissing doesn't
work. I believe it is because I did a vgexport before the 2nd disk went
out of business. And since I cant import the VG because one of the drives
are gone Im kinda in a dead end.

Sincerely
Stefan Wold
