Cool blog! I'll try a run at this on the benchmark.

Has consideration been given to setting multiple properties at once in a
single zfs set command?
For example, consider attempting to maintain quota == reservation, while
increasing both. It is impossible to maintain this equality without some
additional help.
Quota must be increased first

Hi all,
Two separate questions:
1. We have a pool with 134 filesystems which collectively have about
75000 snapshots. The "zfs list" command grows to over 650MB resident

I have implemented this mechanism and it works.
Cool!
Do you think this change will be integrated to opensolaris ?
It's possible, but I'd prefer to first exhaust all options for improving
performance of the ba
If I had had that a few months ago, I might have designed a completely

Great job!

Atul,
libkstat(3LIB) is the library.
"man -s 3KSTAT kstat" should give a good start.

I have to backup many filesystems, which are changing and machines are heavy
loaded.
The idea is to backup online - this should avoid I/O read operations from
disks,
data should go from cache.
Now I'm using script that does snapshot and zfs send.
