actually, nevermind, I figured it out :-) -- Matt +-- |Matthew Plante | University of New Hampshire | InterOperability Lab | Research & Development | SMTP: maplante@iol.unh.edu | Phone: +1-603-862-0203 +- -----Original Message----- From: linux-lvm-bounces@redhat.com [mailto:linux-lvm-bounces@redhat.com]On Behalf Of Matthew Plante Sent: Wednesday, January 25, 2006 10:33 AM To: linux-lvm@redhat.com Subject: removing bad PVs I had created an LVM with 3 iscsi drives. One of the target machines died, which had 2 of the targets in it. So my lvm now says it has 2 bad devices, makes sense: vgscan -P Partial mode. Incomplete volume groups will be activated read-only. Reading all physical volumes. This may take a while... Couldn't find device with uuid 'u1KC7q-D8Bi-qGKp-DJgW-kQ8f-NtB6-GLNuzX'. Couldn't find device with uuid 'YPyDqn-HD9z-2TDc-ZNXP-d4z9-BLtV-BdM0eh'. Found volume group "iol_vg" using metadata type lvm2 pvscan -P Partial mode.

From what I've found, you need to do this with the vgreduce command: vgreduce --removemissing -v iol_vg Finding volume group "iol_vg" Wiping cache of LVM-capable devices Couldn't find device with uuid 'u1KC7q-D8Bi-qGKp-DJgW-kQ8f-NtB6-GLNuzX'.
