[linux-lvm] How do I pvresize?

[linux-lvm] How do I pvresize?

[Glen Harris]

We started running out of space on our backup server, so I bought a
couple of new 250Gb disks, added them to the 16 bay FC RAID array
and expanded the RAID, followed by the slice.

I then went to expand the PV, and got a "Command not implemented yet."
message.

This is a problem. This is a *BIG* problem.

What are my options, short of destroying the volume and starting
from scratch?

I'm pretty new to LVM, so take my comment with a grain of salt.

Why do you need to resize the PV at all? If you need more space, create
a new PV and add it to the LV, that should do the trick.

Re: [linux-lvm] How do I pvresize?

[Glen Harris]

I have already expanded the RAID slice by 250Gb, and now have a
/dev/sda which is 250Gb larger than it was before.

I now cannot remove that disk without either rebuilding the RAID
on the hot spare(back to square one) or destroying the RAID.

Please, can someone help me?

Glen,

If you do a pvscan do you get  'PV "/dev/sda1"  etc' or 'PV "/dev/sda" 
etc'
If you get the former could you not create /dev/sda2 with the extra 250GB 
and add that to the LV as a separate PV
I'm assuming that you can have different partitions on the same array 
(actual disk) defined as separate PVs
I may be completely off track here, please feel free to correct.....

Regards,

Chris.

No, I used the raw device sda. I didn't bother partitioning it, as I
knew I could expand the raid, and grow the PV just like I did back
with LVM-1.
