Hello,
I'm trying to set up an oVirt 3.2.1 cluster with FC storage.
However, I have encountered a problem when adding the storage to the
cluster. The action fails with the error shown in the log fragment
below.

As you can see, the PV is created but the next action (pvchange) fails
due to a wrong lseek parameter value. I have pinpointed the problem to the
metadatacopies parameter (a manually created PV without this parameter
works fine).
I have found a similar issue here:
