Storage Domain Inactive - PV unknown device fix?

Latest response

Hello,

I have a storage domain that went inactive.  Digging into the issue I ran a pvscan on one of my hosts and found that one of the PVs is listed as "unknown device".  I am hoping to find a fix for this.  I see possible solutions with LVM commands but not sure how that might effect RHEV if I modify the PV/VG info.

[root@xxxx]# pvscan

  Couldn't find device with uuid aG5ezr-CGdt-NWR3-cwln-9Lq8-zUF3-prQW03.

Hello, Christopher.  A missing PV seems like an unusual situation.  If there were no Physical Extents allocated in that PV (1023.75 GiB / 1023.75 GiB free), that seems like a good thing.  I believe that it would be best to file a support case.
