Having been on the receiving end of similar advice, it is a frustrating
situation to be in, since you have (and will likely continue to have) the
hardware in production, without much option for replacement.
When we had systems like this, we had a lot of success being aggressive in
swapping out
I'm pretty sure these are just the SAS controller containing about getting
messages it couldn't decode. (in this case, encapsulated SMART command
responses from the drives). AFAIK there is no way to suppress them.

Are you using iSER, or iSCSI over IPoIB? Have you checked your fabrics for
errors (not that those should cause the system to panic).
Also, what kind of infiniband gear are you using?

We're running a mixed system with connectX 1 and 2, and IB only cards work
great with the hermon driver. We haven't had any luck with CX3, but hear
that it is possible. Performance has been quite good, and we haven't needed

Generally speaking -- you use
and other errors that show up in iostat -En output. We remove
them proactively at that point, and get pretty regular failures on a
testing rig afterward.

This is caused by the system attempting to use fastboot on default reboot.
We've disabled that and things seem to work properly; the following
commands do the trick. (the first changes reboot not to use fastboot, the
second causes the system to do a full reboot upon panic)

. Prtconf -vp might be helpful. Presumably this is the
result of one or more devices not doing the right thing for quiesce().

As far as we've been able to tell, zfs replace is a one way street; once
you start the replace, there doesn't seem to be a way to cancel it until it
is completed.
Also, resilvers appear to start from scratch any time anything about the
pool changes. Do you have a drive that is flapping offline
