The HBA I use is an LSI MegaRAID 1038E-R but I guess it doesn't really matter
as most OEM manufacturers such as Dell, Intel, HP, IBM use the LSI 1068e/1078e
or the newer 2008e/2018e Megaraid chips which I believe use pretty much the
same firmware.
So I guess I could change these settings in

I have now upgraded to OpenIndiana b148 which should fix those bugs that you
mentioned. I lost the picture on the monitor but by ssh:ing from another
computer the system seems to be running fine.
The problems have become worse now and I get a freeze every time I try to
access the 8-disk raidz2

Hi Charles,
There are quite a few bugs in b134 that can lead to this. Alas, due to the new
regime, there was a period of time where the distributions were not being
delivered. If I were in your shoes, I would upgrade to OpenIndiana b147 which
has 26 weeks of maturity and bug fixes over b134.

We're having a ZFS performance issue over here that I was hoping you guys could

Is it just ZFS hanging (or what it appears to be is slowing down or
blocking) or does the whole system hang?
A couple of questions
What does iostat show during the time period of the slowdown?
What does mpstat show during the time of the slowdown?
You can look at the metadata

Only the ZFS storage is affected. Any attempt to write to it blocks until the
