Cannot pvcreate a disk

krizevac — Wed, 23 Jan 2002 11:25:19 GMT

I cannot pvcreate a disk. The system returns the message that is already recorded in lvmtab.
The disk is no more used (I'm sure).
Any suggestion ?

pvcreate -f /dev/rdsk/cXtYdZ

but you should be really sure!

You will also want to remoce it from your /etc/lvmtab if it is there..

vgreduce it out of the vg it appears in first.

strings /etc/lvmtab to see which vg it's in.
then vgdisplay -v vgname | grep cXtYdZ
to see if there are extents in use.

You can use pvmove -n src
to move data (lv structures) from the disk to free space on another pv in that vg.. should the pv be in use that is.

Later,
Bill

Move /etc/lvmtab to /etc/sv.lvmtab, or whatever you want to rename it. Then run 'vgscan -a' this will rescan the controllers. You may wish to read the man page for vgscan. I have never encountered any problems running the vgscan.

Hope this helps

Hi:

It would appear that something wasn't done correctly. Try a 'vgexport' of the volume group to cleanup the /etc/lvmtab. After the export, verify that the volume group has been removed from /etc/lvmtab:

# strings /etc/lvmtab

If the /etc/lvmtab is now clean, do:

# pvcreate -f /dev/rdsk/cXtYdZ

Regards!

I don't really understand what you want me to repost. I can repost what I wrote earlier

mv /etc/lvmtab /etc/sv.lvmtab
vgscan -a

You may wish to read the man page on vgscan prior to running the comnmand. I have never had any problems.
