Disk errors that aren't disk errors?

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

Hi,
While testing some Windows backup software I encountered an issue  
with the NetBSD box that I was backing up to. The NetBSD box is an  
amd64 running 5.0_BETA and the disk is a SATA disk in a Vantec eSATA  
dock. I can read and write from the entire disk with dd without  
triggering any kernel messages. The file system is UFS with logging.

The following message log shows my boot messages and the error  
messages (it's just "grep /netbsd"). The errors always show up some  
multiple of two minutes and a few seconds apart. It's always the same  
block number and I/O performance turns to custard for about half a  
minute (where custard is 1MB/s instead of 8MB/s).

Given that dd works, but the mounted file system doesn't, I'm  
guessing that the filesystem is asking the device to do something  
that it can't do. It may be a coincidence, but the first error report  
was two minutes and a few seconds after the backup (via rsync)  
started writing to the disk. The disk had been mounted for some time  
before then. sync(8) did not trigger any error messages.

Disk performance was monitored with "iostat wd0 wd1 wd2 5".

Any ideas would be appreciated.
