Hi all LVM:ers... (Hmm .. almost sound like lamers ;-) )
I have upgraded a Mandrake 9.2 system to Mandrake 10.0 Community. The
lvm1 volumes was imported correctly. When I had the volumes imported and
ready I converted them into lvm2
Now pvscan takes a lot of time. I can't remember if it took a long time
to pvscan before I converted the volumes. At least I know for sure pvscan
ran quite fast on MDK 9.2
Still pvscan takes a long time to complete +1 minute and on my other
systems running lvm1 or lvm2 it takes seconds. Have I done something
wrong?
The /dev/md10 and /dev/md20 are soft mirrors.
Also the summary of GB seem to be wrong.
Output from pvscan -v below
Yes I know. I like partitions or at least liked them. ;-)
I will rebuild this to fewer partitions in the future I am in progress of
doing that for the moment.
pvscan -v
