[linux-lvm] question about physical disks with LVM

[Parker.Christine]

Hello.  I got your name from the LVM man page in Enterprise Linux.  I
have a question about creating one filesystem
on multiple physical volumes:  can the physical volumes be of different
sizes?

Here's our situation:  We have a SAN setup here, and we currently have
one filesystem that spans 10disks.
We want to add 10 more disks (one DAE), but the new disks are larger
than the old ones.  Will we be able to extend the old file
system to include the new disks using LVM?  If not, can you suggest
alternatives for us?

Thanks for any information you can send us.

Yes, your can vgextend your VG to add the new larger drives.  Then you can
either create new LVs or lvextend an existing LV.
