Dear support
when i connect my external usb dvdrom to the sparc machine which has
installed solaris 10u6 based zfs file system,,it return this error:

While doing some performance testing on a pair of X4540's running
snv_105, I noticed some odd behavior while using CIFS.
I am copying a 6TB database file (yes, a single file) over our GigE
network to the X4540, then snapshotting that data to the secondary
X4540.
Writing said 6TB file can peak our g
The vendor wanted to come in and replace an HDD in the 2nd X4500, as it
was "constantly busy", and since our x4500 has always died miserably in
the past when a HDD dies, they wanted to replace it before the HDD
actually died.
The usual was done, HDD replaced, resilvering started and ran for ab

Have you tried "man zpool"? See the entry for detach.

That sounds like a great idea if I can get it to work--
I get how to add a drive to a zfs mirror, but for the life of me I can't find
out how to safely remove a drive from a mirror.
Also, if I do remove the drive from the mirror, then pop it back up in some
unsuspecting (and unrelated) Solaris

Looks like your scrub was not finished yet. Did check it later? You should not
have had to replace the disk. You might have to reinstall the bootblock.

Hi guys!
I'm doing series of tests on ZFS before putting it into production on several
machines, and I've come to a dead end. I have two disks in mirror (rpool).
Intentionally, I corrupt data on second disk:
# dd if=/dev/urandom of=/dev/rdsk/c0d1t0 bs=512 count=20480 seek=10240
So, I've writte

Hi Jim,
The setup is not there anymore, however, I will share as much details
as I have documented. Could you please post the commands you have used
and any differences you think might be important. Did you ever test
with 2008.11 ? instead of sxce ?
I will probably be testing again soon. Any tips

Did anyone share a script to send/recv zfs filesystems tree in
parallel, especially if a cap on concurrency can be specified?
Richard, how fast were you taking those snapshots, how fast were the
syncs over the network. For example, assuming a snapshot every 10mins,
is it reasonable to expect to syn
