A couple of good links [1][2] came up on the Axxs collective email list about monitoring disk activity under Linux using block_dump.
In a nutshell:
kern.debug setup in syslog.conf (it often is; if sync is used disk activity will obviously be greater) echo 1 >/proc/sys/vm/block_dump wait n seconds echo 0 >/proc/sys/vm/block_dump Do various grep'ing on /var/log/debug for READ, WRITE, inode, block, etc
Thanks to Andrew Mc & Torrance.
