wow, that's a truly excelent question.
If you COULD do it, it might work with a simple import
but i have no idea...i'd love to know myself.

Hi,
I'm running Opensolaris 2009.06, and I'm facing a serious performance loss with
ZFS ! It's a raidz1 pool, made of 4 x 1TB SATA disks :

The usage of the pool is for daily backups, with rsync. Some big files are

Hi,
The 4 disks are Western Digital ATA 1TB (one is slighlty different) :
1 x ATA-WDC WD10EACS-00D-1A01-931.51GB

I've done lots of tests (speed tests + SMART reports) with each of these 4 disk

Howdy,
Is dedup on? I was having some pretty strange problems including slow
performance when dedup was on. Disabling dedup helped out a whole bunch. My
system only has 4gig of ram, so that may have played a part too.
Good luck!

Yes, 4 or the 6 Supermicro cards are UIO cards. I added a warning about it.
Thanks.

A really great alternative to the UIO cards for those who don't want the

Hi--
The scenario in the bug report below is that the pool is exported.
The spare can't kick in if the pool is exported. It looks like the
issue reported in this CR's See Also section, CR 6887163 is still
open.
Thanks,

Thanks Dan, this is exactly what I had in mind (hashing the block checksums).
You convinced me to do it independently from zfs.

Roy,
Thanks for the info. Yeah, the bug you mentioned is pretty critical. In
terms of SSDs, I have Intel X25-M for L2ARC and X25-E for ZIL. And the
host has 24G RAM. I'm just waiting for that 2010.03 release or
whatever we want to call it when it's released...

How full is your filesystem? Give us the output of zfs list
You might be having a hardware problem, or maybe it's extremely full.
Also, if you have dedup enabled, on a 3TB filesystem, you surely want more
