Besides the /etc/system, you could also export all
the pools, use mdb to
set the same variable that /etc/system sets, and then
import the pools
again. Don't know of any other mechanism to limit
ZFS's memory foot print.
If you don't do ZFS boot, manually import the pools

Hi,
Other than modifying /etc/system, how can I keep the ARC cache low at boot time?
Can I somehow create an SMF service and wire it in at a very low level to put a
fence around ZFS memory usage before other services come up?
I have a deployment scenario where I will have some reasonably large
Off the lists, someone suggested to me that the Inconsistent
filesystem may be the boot archive and not the ZFS filesystem (though I
still don't know what's wrong with booting b99).
Regardless, I tried rebuilding the boot_archive with bootadm
update-archive -vf and verified it by mounting it

Hi all,
I'm migrating to a new laptop from one which has had hardware issues lately. I
kept my home directory on zfs, so in theory it should be straightforward to
send/receive, but I've had issues. I've moved the disk out of the faulty
system, though I saw the same issue there.
The behavior
One update to this, I tried a scrub. This found a number of errors on old
snapshots (long story, I'd once done a zpool replace from an old disk with
hardware errors to this disk). I destroyed the snapshots since they weren't
needed. The snapshot I was trying to send did not have any errors.
card. I've never
measured this or seen it measured-- any pointers would be useful. I
believe the IOs are 8KB, the application is MySQL.
Thanks in advance,

ok I know zfs-fuse is still incomplete and performance has not been considered,

the limitation that you can't expand a raidz group itself.

Basically, is this a supported zfs configuration?
Can't see why not, but support or not is something only Sun support can
speak for, not this mailing list.
You say you lost access to the array though-- a full disk failure
shouldn't cause this if you were using RAID-5 on
subcommand. In your case, you can run,
for instance: zpool status mypool.
Good luck,

After some quick experimenting, I determined that it is in fact a single
raidz pool with all 47 devices. Apparently something was either done
wrong or miscommunicated in the process.
Sorry for the bandwidth.
