FreeNAS 9.2.1.2-RELEASE
Used to throttle my pool via :
vfs.zfs.write_limit_shift : 9
vfs.zfs.txg.timeout : 1
vfs.zfs.txg.synctime_ms : 200
With 4 X SLOGs we very seldomly saw > 10 ms write latency to the pool. We use it as a NFS Server for ESXI hosts.
Do not know exactly when it happened, but now the first two settings are not even applicable anymore. Hence we are experiencing > 100 seconds write delay yet again :-(
Can anyone guide me to which settings you can 'play' with on the current ZFS pool version?
( That is, if I got it right? )
Brgds.
