COW does apply to zvols. If you

Hi, I'm doing the following actions on my solaris 10 system. Please let me know
if zfs will do the following things: -
Question1: - Will zfs employ ordinary raid0 stripes while creating the file
dust?
Question2: - Since most of my file /exp/dust1 (~74% = 1 - 400MB/1500MB) reside
on
I'm a bit late replying to this, but I'd take the quick dirty approach
personally. When the server is running fine, unplug one disk and just see
which one is reported faulty in ZFS.
A couple of minutes doing that and you've tested that your raid array is
working fine and you know exactly

ZFS seems to treat files filled with zeroes as sparse files, regardless

The only supported controller I've found is the Areca ARC-1280ML. I want to
put it in one of the 24-disk Supermicro chassis that Silicon Mechanics builds.
Has anyone had success with this card and this kind of chassis/number of drives?
cheers,
Blake

change zvol permissions to whatever you want?

No, that is definitely not expected.
One thing that can hose you is having a single disk that performs
really badly. I've seen disks as slow as 5 MB/sec due to vibration,
bad sectors, etc. To see if you have such a disk, try my diskqual.sh
script (below). On my desktop system, which has 8
Not at present, but it's a good RFE. Unfortunately it won't be
quite as simple as just adding an ioctl to report the dnode checksum.
To see why, consider a file with one level of indirection: that is,
it consists of a dnode, a single indirect block, and several data blocks.
The indirect block

I had to change the above line to

Sort of, though its not raid0. It will balance the writes across the
members of its storage pools. So in your 3 disk zpool, the writes

More RAM always helps ;)
