Brandon,
Thanks for replying to the message.
I believe that this is more related to the variable stripe size of RAIDZ
than the fdisk MBR. I say this because the disk works without any issues in
a mirror configuration or as standalone reaching 80 MB/s burst transfer
rates.

On the PCIe side, I noticed there's a new card coming from LSI that claims
150,000 4k random writes. Unfortunately this might end up being an OEM-only
card.
I also notice on the ddrdrive site that they now have an opensolaris driver and
are offering it in a beta program.

Hi,
I known that ZFS is aware of I/O errors, and can alert or disable a crappy disk.
However, ZFS didn't notice at all these service time problems.
I think it is a good idea to integrate service time triggers in ZFS !
What to you think ?
Best regards !

If you do not care about this NFS problem (or the others) then maybe
you can just disable the ZIL. It is a matter of working through step

Actually, it seems a common problem with WD EARS drives (advanced format) !

Hi guys.
yep I know about the ZIL, and SSD Slogs.
While setting Nextenta up it offered to disable the ZIL entirely. For

once that feature is released.) I'll end up disabling the ZIL

For the record, in case anyone else experiences this behaviour: I tried
various things which failed, and finally as a last ditch effort, upgraded my

This is intresting. I thought all Vertex 2 SSDs are good choices for ZIL

According to http://www.legitreviews.com/article/1208/1/ Vertex 2 LE,

Does the pool tank actually have 6 disks c7t0-c7t5 and c7t3d0 is now
masking c7t5d0 or it is a 5-disk configuration with c7t5 repeated twice?
If it is the first case (c7t0-c7t5), then I would check how these
devices are connected before attempting to replace the c7t3d0 disk.

The SATA power connector supplies 3.3, 5 and 12v. A complete

probably ignore 3.3v and 12v.
