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

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 ) -John On Fri, May 16, 2014 at 1:54 AM, Morten A.
