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?

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?

With regard to multiuser systems and how that negates the need to
defragment, I think that is only partially true. As long as the files
are defragmented enough so that each particular read request only
requires one seek before it is time to

With appropriate write caching and grouping or re-ordering of writes
algorithms, it should be possible to minimize the amount of file
interleaving and fragmentation on write that takes place.
To some degree, ZFS already does this. The

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
interpretation is
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

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

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 :)

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:
