The difference between multi-user thinking and single-user thinking is
really quite dramatic in this area. I came up the time-sharing side
(PDP-8, PDP-11, DECSYSTEM-20); TOPS-20 didn't have any sort of disk

I recently created a test zpool (RAIDZ) on some iSCSI shares. I made a few
test directories and files. When I do a listing, I see something I've never
seen before:

Cool, we can get the Intel X25-E's for around $300 a piece from HP with the
sled. I don't see the X25-M available so we will look at 4 of the X25-E's.
Thanks :)

Here is the solution (thanks to Gavin Maltby from mdb forum):
Boot with -kd option to enter in kmdb and type the following commands:
aok/W 1
::bp zfs`zfs_panic_recover
:c
wait that it stops at breakpoint then type this:
zfs_recover/W1
:z
:c

We are looking into the possibility of adding a dedicated ZIL and/or L2ARC
devices to our pool. We are looking into getting 4 – 32GB Intel X25-E SSD
drives. Would this be a good solution to slow write speeds? We are currently
sharing out different slices of the pool to windows servers using com

Maybe this is the wrong thread. I have noticed that an old pool can take 4
hours to scrub, with a large portion of the time reading from the pool disks at
the rate of 150+ MB/s but zpool iostat reports 2 MB/s read speed. My naive

If I launch opensolaris with "-kd" I'm able to do this:
aok/W 1
but if I type:
zfs_recover/W 1
then I get an unkown symbol name error.
Any idea how I could force this variables?

I can't edit now my /etc/system file because system is not booting.
Is there a way to force this parameters to Solaris kernel on booting with Grub?
