input/output errors and out of inodes and file system full

[reed%reedmedia.net@localhost]

My xen provider moved me from xen2 to xen3.

I am using a kernel for XEN3_DOMU that adds pf and pflog.

After about five hours, attempting to run new commands failed
with ksh input/output errors. But some commands, like ls and
httpd running in background continued to work.

dmesg had:

I couldn't use df or any tools to see what was going on.

Anyone seen anything like this?

My kernel is netbsd-3.
