ARCSTAT Kstat Definitions
Would someone "in the know" be willing to write up (preferably blog) definitive definitions/explanations of all the arcstats provided via kstat? I''m struggling with proper interpretation of certain values, namely "p", "memory_throttle_count", and the mru/mfu+ghost hit vs demand/prefetch hit counters. I think I''ve got it figured out, but

ZFS slows down over a couple of days
Hi all,
I have exchanged my Dell R610 in favor of a Sun Fire 4170 M2 which has
32 GB RAM installed. I am running Sol11Expr on this host and I use it to
primarily serve Netatalk AFP shares. From day one, I have noticed that
the amount of free RAM decereased and along with that decrease the
overall performance of ZFS decreased as well.
Now, since I am still quite a Solaris newbie, I seem to

Why does ARC grow above hard limit?
I would appreciate if somebody can clarify a few points.
I am doing some random WRITES (100% writes, 100% random) testing and observe that ARC grows way beyond the "hard" limit during the test. The hard limit is set 512 MB via /etc/system and I see the size going up to 1 GB - how come is it happening?
mdb''s ::memstat reports 1.5 GB used - does this include ARC as well or is

[storage-discuss] high read iops - more memory for arc?
Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms).
I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

high read iops - more memory for arc?
I''m running into a issue where there seems to be a high number of read iops hitting disks and physical free memory is fluctuating between 200MB -> 450MB out of 16GB total. We have the l2arc configured on a 32GB Intel X25-E ssd and slog on another32GB X25-E ssd.
According to our tester, Oracle writes are extremely slow (high latency).
Below is a snippet of iostat:

Monitoring ZFS host memory use
Hi,
Please forgive me if my searching-fu has failed me in this case, but
I''ve been unable to find any information on how people are going about
monitoring and alerting regarding memory usage on Solaris hosts using
ZFS.
The problem is not that the ZFS ARC is using up the memory, but that the
script Nagios is using to check memory usage simply sees, say 96% RAM
used, and alerts.
