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
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

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 )
