Hi,

Have you the last sam and LVM patches ?
Does the command line work ?

For your problem with lvmtab you can move /etc/lvmtab to lvmtab.old and recreate it
by vgscan.

Hello,

First try a vgreduce -f vg01

First do a
vgdisplay -v /dev/vg01
to find out the
value of CurPV and Act PV
If the value differ then you have to do a

vgreduce -f /dev/vg01
to reduce the missing physical volumes.

Else just move your /etc/lvmtab file and do a vgscan
to create a new /etc/lvmtab file.
Also do a ioscan and check whether all the disks are in the CLAIMED state.


Thanks

I think that your lvmtab corrupt is, so you need to rename lvmtab to lvmtab.old en then vgscan to create a new one, just read man vgscan.
