Hi,
soon it'll be time to migrate my patchwork pool onto a real pair of
mirrored (albeit USB-based) external disks.
Today I have about half a dozen filesystems in the old pool plus dozens of
snapshots thanks to Tim Bray's excellent SMF snapshotting service.

Hi,
Today I have about half a dozen filesystems in the old pool plus dozens of
snapshots thanks to Tim Bray's excellent SMF snapshotting service.
I'm sorry I mixed up Tim's last name. The fine guy who wrote the SMF snapshot
service is Tim Foster. And here's the link:
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.
I want to automate this operation and add new
I have other question about replication in this thread:

zfs send then would:
1. create replicate snapshot if it does not exist
2. send data
3. wait 10 seconds
4. rename snapshot to replicate_previous ( destroy previous if exists )

All snapshot operations are done in kernel - it works
Hi,
Does ZFS has support for kstats? If I want to extract information
like no of files commited to disk during an interval, no of
transactions performed, I/O bandwidth etc, how can I get that
information?

Out of curiosity, what is the timing difference between a userland script
and performing the operations in the kernel?

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

If I had had that a few months ago, I might have designed a completely
different system.
Great job!

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

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
before printing its output. This doesn't overly bother me since the
box in question (snv53) has plenty of

Operation takes 15 - 20 seconds
In kernel it takes ( time in ms ):
[between 2.5 and 14.5 seconds]
Very nice improvement.
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
Cool blog! I'll try a run at this on the benchmark.

right on for optimizing throughput on solaris .. a couple of notes
though (also mentioned in the QFS manuals):
- on x86/x64 you're just going to have an sd.conf so just increase
the max_xfer_size for all with a line at the bottom like:
sd_max_xfer_size=0x80;
(note: if you look
talking of which,
what's the effort and consequences to increase the max allowed block
size in zfs to highr figures like 1M...
