I had another crash/hang, and decided to boot kmdb. I'd put up with the
performance loss for whatever length of time it took if it meant finding the
problem.

However, trying to "boot -k" got me this:

Rebooting with command: boot -k
Boot device: /pci@8,600000/SUNW,qlc@4/fp@0,0/disk@w21000020375c0519,0:a File and args: -k

.... which isn't what I expected.

I think I'm going to give up on ZFS on this machine and go back to UFS,
which is a bit of a pain. But it's the only way I can think of to eliminate
ZFS as the cause... unless someone can suggest something.

Well, it crashed, just using UFS. Odd that I could get the filesystem
unmounted, but prtvtoc on the disk hung... as did every other process
which tried to open up a file. Then powering off the firewire enclosure
panicked the machine. I was hoping just for some resets/EXIO errors.

Oh well. ZFS not to blame. Now I just have to shop for some disks for
this thing.

And throw the enclosure at someone I don't like.

As a matter of interst, what make/model are they? I know what to avoid
then, as I too have the same machine.

It's a Western Digital 160G ATA100 disk in a Vantec NexStar FW400 enclosure.
I was warned by a friend (much too late, of course) that they tend to get
quite warm; although this case never seemed to get hot, and rarely failed
during high activity, only idling.

I'll be trolling around eBay for some 73G internal disks, since I'd like
to upgrade (and mirror) the root disk. They seem to be going for about
$125 CAD in some instances. I can probably choke that down.

FWIW (as you probably already know) there are external enclosures
w/fans available. I use an AMS Venus (USB) model that has a nice big
- and quiet - fan. Not a lot of experience with it but it works and
seems to stay fairly cool. My friends at NewEgg stock it and others:

A neighbor who does a lot of work w/external drives wouldn't use
any exclosure that didn't have a fan.

Just sticking my beak in...
