Hi David,
why not just use a couple of SAS expanders?

Mirrored sets do protect against disk failure, but most of the time you'll find
proper backups are better as most issues are more on the order of "oops" than
"blowed up sir".
Perhaps mirrored sets with daily snapshots and a knowedge of how to mount
snapshots as clones so that you can pull a cop

I had some issues with direct send/receives myself. In the end I elected to

otherside. This has been working fine 3 times a day for about 6 months now.

value involved.

My zfs filesystem hangs when transferring large filesystems (>500GB)
with a couple dozen snapshots between servers using zfs send/receive
with netcat. The transfer hangs about halfway through and is
unkillable, freezing all IO to the filesystem, requiring a hard
reboot. I have attempted this three

You may be absolutely right. CPU clock frequency certainly has hit a wall at
around 4GHz. However, this hasn't stopped CPUs from getting progressively
faster. I know this is mixing apples and oranges, but my point is that no
matter what limits or barriers computing technology hits, someone co

thanks for the reply. As you can see I already use that option. But that
doesn't prevent the filesystems in the pool from mounting when I import the

to prevent the filesystems from mounting automatically.

Hey All,
I'm having some issues with a snv_126 file server running on an HP ML370 G6
server with an Adaptec Raid Card (31605). The server has the rpool, plus two
raidz2 data pools (one is 1.5TB and 1.0TB respectively). I have been using
e-sata to backup the pools to a pool that contains 3x 1.5 Tb
