Well I do have a plan.
Thanks to the portability of ZFS boot disks, I'll make two new OS disks on
another machine with the next Nexcenta release, export the data pool and swap
in the new ones.
That way, I can at least manage a zfs scrub without killing the performance and
get the Intel SSD's I
Nothing like a "heart in mouth moment" to shave tears from your life.
I rebooted a snv_132 box in perfect heath, and it came back up with two FAULTED
disks in the same vdisk group.
Everything an hour on Google I found basically said "your data is gone".
All 45Tb of it.

The WD10EARS disks don't work well.
I had too many issues with timeouts that disappeared when replacing them with
ST32000542AS drives.
My next challenge is to get the LSI 3081 to boot off the disk I want it to, and
then to get multipath functional.
Has anyone else had issues with the LSI IT mo
The results are in:
My timeout issue is definitely the WD10EARS disks.
Although differences in the error rate was seen with different LSI firmware
revisions, the errors persisted. The more disks on the expander, the higher the
number with iostat errors.
This then causes zpool issues (disk failur
I did see that and confirmed the support has made it into the 130 release I'm
testing with.
However, the WD10EARS does not expose 4k sectors to the outside world, so it is
not identified as supporting it.
Correct alignment, to ensure best performance of the internal translation,
seems to be the
Update:
For the WD10EARS, the blocks appear to be aligned on the 4k boundary when zfs
uses the whole disk (whole disk as EFI partition).

I'm looking into the alignment implications for the WD10EARS disks.
It may explain my issues.
I seem to recall boot issues in some of the LSI release notes affecting other
boot devices. I think it takes over boot responsibility.
I've encountered this sort of issue over the years with many scsi ca
My experience was different again.
I have the same timeout issues with both the LSI and Supermicro cards in IT
mode.
IR mode on the Supermicro card didn't solve the problem, but seems to have
reduced it .

Hi Giovanni,
I have seen these while testing the mpt timeout issue, and on other systems
during resilvering of failed disks and while running a scrub.
Once so far on this test scrub, and several on yesterdays.
I checked the iostat errors, and they weren't that high on that device,
compared to
An update:
Well things didn't quite turn out as expected.
I decided to follow the path right to the disks for clues.
Digging into the adapter diags with LSIUTIL, revealed an Adapter Link issue.

I can produce the timeout error on multiple, similar servers.
These are storage servers, so no zones or gui running.

Ben,
I have found that booting from cdrom and importing the pool on the new host,
then boot the hard disk will prevent these issues.
That will reconfigure the zfs to use the new disk device.
When running, zpool detach the missing mirror device and attach a new one.

Thanks Will,
I thought it might be an i2c interface port to the psu, but obviously much
simpler.
I'll probably use a small picaxe micro, since I have a few here & have used
them before.
I used them to 'translate' the replacement fans clock pulse to what the
monitoring circuit needed in a few V2
Will,
sorry for picking an old thread, but you mentioned a psu monitor to supplement
the CSE-PTJBOD-CB1.
I have two of these and am interested in your design.
Oddly, the LSI backplane chipset supports 2 x i2c busses that Supermicro didn't
make use of for monitoring the psu's.

Check if your card has the latest firmware.

The earlier (2008) Opensolaris drivers tended to crash the server if you pulled
out an active drive. It may have improved in later releases.
In the case of the Sun Storage Appliances, the sata (and sas) drivers used are
different from those in Opensolaris and are considerably better featured.
My
I'd recommend a SAS non-raid controller (with sas backplane) over sata.
It has better hot plug support.
I use the Supermicro SC836E1 and a AOC-USAS-L4i with a UIO M/b.

I have used these cards several UIO capable Supermicro systems and Opensolaris,
with the Supermicro storage chassis and up to 30 stata 1Tb disks.
With IT mode firmware (non-raid) they are excellent. They usually have the
"hardware assisted" raid firmware by default.
The card is designed for the
Hi,
Is it possible to import a zpool and stop it mounting the zfs file systems, or
override the mount paths?
