If you are using rsync already, I would run it on server in daemon mode. And
there are Windows clients that support rsync protocol.

Hi all,
I have built out an 8TB SAN at home using OpenSolaris + ZFS. I have
yet to put it into 'production' as a lot of the issues raised on this
mailing list are putting me off trusting my data onto the platform
right now.
Throughout time, I have stored my personal data on NetWare and now NT

Hi again,
brief update:
the process ended successfully (at least a snapshot was created) after
close to 2 hrs. Since the load is still the same as before taking the
snapshot I blame other users' processes reading from that array for the
long snapshot duration.

If you have any backups of your boot volume, I found that the pool can be
mounted on boot provided it's still listed in your /etc/zfs/zpool.cache file.
I've moved to OpenSolaris now purely so I can take snapshots of my boot volume
and backup that file.
The relevant bug you need fixing is this

And this s confirmed by zdb, after loong wait for comparison of data and
checksums: no data errors.

Well, I don't have a huge amount of experience in Solaris, but I can certainly
share my thoughts.
1. BACKUPS
Always ensure you have backups of the pool. Ideally stored in a neutral
format. Our plan is to ensure that all ZFS stores are also stored:
- on tape via star
- on an off-site ZFS s
No takers? :)

Hello there...
I did see that already, talk with some guys without answer too... ;-)
Actually, this week i did not see discrepancy between tools, but the pool
information was wrong (space used). Exporting/importing, scrub, and etc, did
not solve. I know that zfs is "async" in the status report
I'm also seeing a very slow import on the 2008.11 build 98 prerelease.

Yuvraj,
I see that you are using files as disks.
You could write a few random bytes to one of the files and that would
induce corruption.
To make a particular disk faulty you could mv the file to a new name.
Also, you can explore the zinject from zfs testsuite . Probably it has a
way to induce

Greetings.
I have a X4500 with an 8TB RAIDZ datapool, currently 75% full. I have it carved
up into several filesystems. I share out two of the filesystems
/datapool/data4 (approx 1.5TB) and /datapool/data5 (approx 3.5TB). THe data is
imagery, and the primary application on the PCs is Socetset.
Hi all,
I have a little question.
WIth RAID-Z rules, what is the true usable disks space?
Is there a calcul like any RAID (ex. RAID5 = nb of disks - 1 for parity)?
Thank you for your help, i found everywhere on the web and i don't found my
answer...

It depends on what data you write to it, how the writes are done, and
what compression or redundancy parameters are set.

Are there plans to make the Sun Web Console available in OpenSolaris? I've used
it on Solaris 10 and it's a great tool, I think it'd make using/administering
ZFS a lot easier for those new the Solaris and ZFS. Thoughts?

I've had serious problems trying to get Windows to run as a NFS server with
SFU. On a modern raid array I can't get it above 4MB/s transfer rates. It's
slow enough that virtual machines running off it time out almost every time I
try to boot them.
Oddly it worked ok when I used an old IDE dis

We have 135 TB capacity with about 75 TB in use on zfs based storage.
zfs use started about 2 years ago, and has grown from there. This spans
9 SAN appliances, with 5 "head nodes", and 2 more recent servers running
zfs on JBOD with vdevs made up of raidz2.
So far, the experience has been ve

I've a report that the mismatch between SQLite3's default block size and
ZFS' causes some performance problems for Thunderbird users.
It'd be great if there was an API by which SQLite3 could set its block
size to match the hosting filesystem or where it could set the DB file's
record size to match
