After the last update (FreeNAS-9.3-STABLE-201504152200, installed yesterday April 18th), my production pool became very slow but my backup pool was fine. There were no warnings or errors from zpool status or the GUI (no messages in the console or warning lamp). Very strange. An rsync of a 6GB file transferred at over 130MBps on the backup pool but at ~5MBps on the production array (I did not let it finish to get statistics).

I shut down the FreeNAS server completely and then re-powered it. Now the same file will rsync on the production pool at:

Code:
sent 6.05G bytes  received 35 bytes  191.99M bytes/sec
total size is 6.05G  speedup is 1.00


and on the backup pool at:

Code:
sent 6.05G bytes  received 35 bytes  135.91M bytes/sec
total size is 6.05G  speedup is 1.00


Would there be any logs that I could look into to see what was going on? System stats are in my sig.

Cheers,

No I did not. Strange issue. Seems to be gone though.
