problem with pvcreate

Parvin Hosseini_1 — Tue, 20 Nov 2001 15:34:18 GMT

I am trying to set mirror on my machine X.
The first step that I do is:

pvcreate -B /dev/rdsk/c1t0d0

C1t0d0 is the new disk which should be taken as mirror for c1t2d0.

The error message by pvcreate is as follow:

The physical volume /dev/dsk/c1t0d0 is belong to an exported volume group.

notice: This disk was involved in mirroring on another machine Y. But I need to set the mirror on my machine X.

Does anybody know what the problem is?

thank you

pvcreate -f -B /dev/rdsk/[etc].

Force option on pvcreate will instruct it to ignore existing file system.

are you saying this disc WAS used on another system, and now you REALLY want to use it again?

If so, add in the -f (force option) to your command:
pvcreate -f -B

The problem is that pvcreate can spot the VGRA area on a disk which has previously been used.
If your COMPLETELY SURE the disk is not in use anywhere else then use:

pvcreate -fB ...

Hi,

use the -f (force option) with pvcreate command to do this. This will force the pvcreate command to run on the disk, irrespective of what is on the disk

pvcreate -f -B /dev/rdsk/cxtydz

Hi Parvin:

If you are absolutely sure that this is the disk you want to 'pvcreate', you will need to "force" the operation to erase existing LVM information from it. Do:

# pvcreate -B -f /dev/rdsk/c1t0d0

Hi,

You can do:

# pvcreate -f -B ....

but if it doesnt work also, you can firest

# dd if=/stang/vmunix of=/dev/dsk/c1t0d0
# pvcreate -f -B ...
