Long time Reader. First time Poster!.
(end awkward moment)
I have an LSI mfi based storage controller LSI MegaRAID SAS 9261-8i and I get the following issues
mfi0: COMMAND 0xffffff80005b1ee0 TIMEOUT AFTER 123 SECONDS -->
mfi0: COMMAND 0xffffff80005b1ee0 TIMEOUT AFTER x SECONDS
during this time. any services attached to the ZFS volume crashes
Feb 14 10:19:03 freenas cnid_dbd[3067]: read: Connection reset by peer
Feb 14 10:19:03 freenas cnid_dbd[3067]: error reading message header: Connection reset by peer
But if I run a
mfiutil show adapter
the time out stops counting up and resets to 0 and all is ok for 20 seconds or so then the
mfi0: COMMAND 0xffffff80005b1ee0 TIMEOUT starts again.
here is the cache settings on one of the disks
mfiutil cache mfid0
mfi0 volume mfid0 cache settings:
I/O caching: disabled
write caching: write-back
read ahead: none
drive write cache: disabled
I changed the caching method from write-back to write-through (cahce - write straight to disk)
mfiutil cache mfid0
mfi0 volume mfid0 cache settings:
I/O caching: disabled
write caching: write-through
read ahead: none
drive write cache: disabled
Issue Stopped..
okay I would really like to know is why having write-back option Fail with time outs? hardware/firmware issue? freenas mfi drivers out of date?
I would love to use the write-back feature as performace boost is awesome?
any takers?
