every single disk in SATABeast is not possible. The smallest entities
I can create on the SATABeast are RAID 0 or 1 arrays. With RAID 1 I'll
loose too much disk space
Hi,
there was recently a bug reported against EXT4 that gets triggered by
KDE: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/317781
Now I'd like to verify that my understanding of ZFS behavior and
implementations is correct, and ZFS is unaffected from this kind of
issue. Maybe
The underlying problem with ext4 is that some kde executables do
something like this:
1a) open and read data from file x, close file x
1b) open and truncate file x
1c) write data to file x
1d) close file x
or
2a) open and read data from file x, close file x
2b) open and truncate file x.new
2c)

I have a H8DM8-2 motherboard with a pair of AOC-SAT2-MV8 SATA
controller cards in a 16-disk Supermicro chassis.
I'm running OpenSolaris 2008.11, and the machine performs very well
unless I start to copy a large amount of data to the ZFS (software
raid) array that's on the Supermicro SATA
Hello,
I want to setup an opensolaris for centralized storage server, using
ZFS as the underlying FS, on a RAID 10 SATA disks.
I will export the storage blocks using ISCSI to RHEL 5 (less than 10

The copy operation will make all the disks start seeking at the same time and
will make your CPU activity jump to a significant percentage to compute the
ZFS checksum and RAIDZ parity. I think you could be overloading your PSU
because of the sudden increase in power consumption...
However if
I'm working on testing this some more by doing a savecore -L right
after I start the copy.
BTW, I'm copying to a raidz2 of only 5 disks, not 16 (the chassis
supports 16, but isn't fully populated).
So far as I know, there is no spinup happening - these are not RAID
controllers, just dumb SATA
Okay so for some reason my Opensolaris 106 installation quit booting
properly (completely seperate problem). At this point I was still able
to boot into safe mode, but not into a normal desktop session.
First a disk failed, I replaced this disk with another. The array
completely resilvered. I was

I think that TMC Research is the company that designed the

looks worth a go otherwise:
if the boot disk is also off that controller it may be too hosed to
write anything to the boot disk hence FMA doesn't see any issue when it
comes up. Possible further actions:
- Upgrade FW of controller to highest or known working level
- Upgrade driver or OS
Any chance this could be the motherboard? I suspect the controller.
The boot disks are on the built-in nVidia controller.

Hi Eric,
Thanks for the quick response. Then on hostB, the new LUN will need the same
amount of disk space for the pool, as on hostA, if I'm understanding you
correctly. Correct? Thanks!

I guess I didn't make it clear that I had already tried using savecore
to retrieve the core from the dump device.
I added a larger zvol for dump, to make sure that I wasn't running out

Looks like I may have slightly answered my question.
I found that it uses the server board S5000PSL, which is in the HCL:

It's not listed in the OpenSolaris one, only the Solaris one. I would

Hi Eric,
Thanks. That scenario makes sense. I have a better of how to set things up
now. It's a three-step process, which I didn't realize.

That explanation help clarify things. I have another question, but maybe it'll

If you're having issues with a disk contoller or disk IO driver its highly
likely that a savecore to disk after the panic will fail. I'm not sure how to
work around this, maybe a dedicated dump device not on a controller that uses a
different driver then the one that you're having issues with?
