[ovirt-users] IO errors when adding new disk on iSCSI storage

[John Taylor]

Hi Morten,
My understanding of thin disks on a block domain is that vdsm traps
ENOSPC on the thin lv and uses the mailbox to get the SPM to extend
it.   See a presentation by Nir
http://www.ovirt.org/File:Storage-mailbox.odp
I thought I saw somewhere there were some changes/bugs around that for
allowing mixed data centers (both block and file domains). ...just
looked now and this bz looks relevant
https://bugzilla.redhat.com/show_bug.cgi?id=1083476


So maybe you could check the engine logs and spm logs for that flow
(sorry I can't tell you any specifics about what you should look for )
