FreeNAS 11.2-RELEASE
Issue: After creating a new iSCSI zvol on a newly built system, I created periodic snapshots every 15 minutes. This worked fine for the first 12 hours, then I started getting out of space alerts. There is plenty of available space on the zVol. Note: the zVol is set to 80% of the pool. There is still plenty of space left within the zvol, nearly 50%.
Any idea why I can't create snapshots now? I don't even know where to look. I deleted all existing snapshots and still cannot manually create one. I read somewhere that the problem might have to do with zfs reserving 50% for snapshots, and to check if refreservations is set to none (mine is set to none). I experimented with setting a quota, no luck. I experimented with setting a reservation. Both of these resulted in the same out of space response.
