That was part of my testing of the RAID controller settings; turning off the controller cache dropped me to 20 mb/sec read & write under raidz2/zfs. --Ross -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolari

Okay, after doing some testing, it appears that the issue is on the ZFS side. I fiddled around a while with options on the areca card, and never got any better performance results than my first test. So, my best out of the raidz2 is 42 mb/s write and 43 mb/s read. I also tried turning off crc'

[zfs-discuss] zpool import of bootable root pool renders it unbootable

I am running OpenSolaris 2008.05 as a PV guest under Xen. If you import the bootable root pool of a VM into another Solaris VM, the root pool is no longer bootable. It is related to the device associated to the pool, which is originally c4d0s0, but on import (-f) becomes c0d2s0 in this case.

define a lot :-) We are doing about 7-8M per second which I don't think is a lot but perhaps it is enough to screw up the estimates? Anyhow the resilvering completed about 4386h earlier than expected so everything is ok now, but I still feel that the way it figures out the number is wrong. Any

Hi Mertol, Yes, I'm using zfs send -i to just send the changes rather than the whole thing. I'll have a think about your suggestion for deleting snapshots too, that does sound like a good idea. Unfortunately I won't be able to synchronise any applications with this script. It's backing up

Re: [zfs-discuss] Which is better for root ZFS: mlc or slc SSD?

For a root device it doesn't matter that much. You're not going to be writing to the device at a high data rate so write/erase cycles don't factor much (MLC can sustain about a factor of 10 more). With MLC you'll get 2-4x the capacity for the same price, but again that doesn't matter much f
