Here's an odd one. I built a system that boots/roots off a UFS 2 GB CF card in a primary IDE slot. There are also on-board SATA ports and I've plugged a 500 GB drive in for storing backups - the whole thing given over to a ZFS pool with multiple file systems underneath (dedupe off, compression LZJB, copies=2)
Everything is nicely stable until I try to use rsync to push a significant amount (50 GB-ish) over to the drive. At some point during disk writes, the drive suddenly disappears as though it has been literally disconnected from the port.
Only thing that brings the drive back is atotal reboot HARD power off and back on.
Any ideas what might cause this? I was thinking drive temperature could be, although I have a fan pointed at it? Bad RAM? Etc?
