Jason,
There is no documented way of limiting the memory consumption.
The ARC section of ZFS tries to adapt to the memory pressure of the system.
However, in your case probably it is not quick enough I guess.
One way of limiting the memory consumption would be limit the arc.c_max
This (arc.c_max
Hello,
Is there a way to set a max memory utilization for ZFS? We're trying
to debug an issue where the ZFS is sucking all the RAM out of the box,
and its crashing MySQL as a result we think. Will ZFS reduce its cache
size if it feels memory pressure? Any help is greatly appreciated.
Best Regard

Hey Peter,
If I recall correctly, the result was there was a very slight space-efficiency
benefit of using a multiple of 2 vdevs for raidz1 and of 3 vdevs for raidz2 --
doing this can reduce the number of 'skipped' blocks. That said, the advantage
is very slight and is only really relevant when th
I have a snv_52 server that I want to upgrade to the latest, either via a
non-debug build or a simple fresh install. I don't know which yet as I
have not decided.
I have a pile of disks hanging off it on two controllers, c0 and c1.
The disks on c1 are in a zpool thus :
bash-3.1$ zpool status
The aclmode and aclinherit properties are exactly what I was looking for.
Thanks Mark!
