This problem only manifests itself when dealing with many small files
over NFS. There is no throughput problem with the network.
But there could be a _latency_ issue with the network.

If there was a latency issue, we would see such a problem with our

For ZIL sizing, I'm using either 1 or 2 32G Intel X25-E SSDs in my
tests, which, according to what I've read, is 2-4 times larger than the
maximum that ZFS can possibly use. We've got 32G of system memory in

not like 15 years ago when a file system was 2GB total,
and 23% free meant a measely 460MB to allocate from.
640GB is a lot of space, and our largest writes are less
than 5MB.

There is not a way to do that currently, but I know it's coming down the
road.

I'm running ClearCase on a Solaris 10u4 system. Views vobs.
I lock the vob, snapshot /var/adm/rational, vobs, views, then unlock the vobs.
We've been able to copy the snapshot to another server restore.
I believe ClearCase is supported by Rational on ZFS also. We would not have

If the SSD is able the drain it's internal buffer to flash on a power

Hello,
My apologies if this has been discussed before or if this is
the wrong place to discuss Solaris 10 U6 issues..
I am investigating using ZFS as a possible replacement for SVM for
root disk mirroring. So far, I have installed the system with the
new ZFS option in the text installer of U6.
Hi Pål,
CR 6420274 covers the -p part of your question. As far as kstats go, we only
have them in the arc and the vdev read-ahead cache.

Maybe ZFS hasn't seen an error in a long enough time that it considers

What does 'zpool status -xv'
zfs set only seems to accept an absolute path, which even if you set it
to the name of the pool, isn't quite the same thing as the default.
see my other thread about set mountpoint but don't mount?.
