Hello,
Using 3.12.0 and ext4fs with 2 x SSDs in a RAID-1 configuration on a
3ware HW RAID card, no md/dm, I noticed the following recently:
[178339.353565] sda2: WRITE SAME failed. Manually zeroing.
It seems to be similar to this issue here:
http://permalink.gmane.org/gmane.linux.kernel/1494512
Relevant logs:
[178339.353519] 3w-sas: scsi0: ERROR: (0x03:0x0101): Invalid command
opcode:opcode=0x41.
[178339.353565] sda2: WRITE SAME failed. Manually zeroing.
Is this something I should be worried about?
I am running a database on the host, could that be the cause of it?
(in the related post, he was also running a DB).
Justin.

No, it just means that your 3ware controller does not handle the WRITE
SAME command and we fall back to manually writing out zeroes.
I posted a patch a while back that prevents WRITE SAME being issued for
controllers that do not pass the commands through to disk directly:

Awesome, thank you! This patch is over a month old, do you know if is
currently in mainline? I'll also update my case with 3ware/LSI.

Could it possibly get added to 3.12.x -stable as well? I've patched against
3.12.0 for now -- I'll let you know if there are any issues-- so far so
good, thanks again.

System uptime with the patch is 7+ days under extensive load at times and
I've had no issues to date.
I just checked the current linux git repo (3.13-rc2) and found this patch
has not been included.
Please advise if any further testing or validation needs to be completed to
help get this into -stable/-mainline.

It needs to get into Linus's tree first, after that, let

sta...@vger.kernel.org know the git commit id and I'll be glad to queue
it up for a stable kernel release.

James has it queued in scsi/fixes. It'll make it to Linus on the next
pull and it has been tagged for inclusion in stable.
