Here's the weird thing. I've stopped just about everything. The one thing I cannot stop is FTP and NFS. Samba, syslog, mysql, postfix, cron have all been shut down temporarily with no effect.

NFS is not exporting the disk in question. FTP has several log files open. The culprit might be /var/log/wtmp as the other logs are relatively idle (only when users are actually transferring, which is relatively rate).

Code:
proftpd 12155  ftp    3w   REG        8,4   5086871 12767115 /var/log/proftpd/replicate.log
proftpd 12155  ftp    6w   REG        8,4   1924515 12767452 /var/log/proftpd/auth.log
proftpd 12155  ftp    7w   REG        8,4   4340157 12767454 /var/log/proftpd/access.log
proftpd 12155  ftp    8u   REG        8,4      4936  9755364 /var/run/proftpd/proftpd.scoreboard
proftpd 12155  ftp   11w   REG        8,4  68647296 12767550 /var/log/wtmp
proftpd 12155  ftp   12w   REG        8,4   4668852 12767913 /var/log/proftpd/transfer.log

I rotated the wtmp file. The new one is less than 5k in size, so I think I can eliminate it. Watching "du -sh /var/log/proftpd" leads me to conclude that it is also not changing in size.

Any known subversive software that writes to disk a lot?

NAME
ftpcount - show current number of connections for each proftpd server configuration SYNOPSIS
ftpcount DESCRIPTION
The ftpcount command shows the current number of connections per server and virtualhost/anonymous configuration defined in the proftpd.conf file. Connections spawned by inetd are counted separately from those created by a master proftpd standalone server. OPTIONS
-h,--help Display a short usage description, including all available options. -f,--file scoreboard-file Specify the full path to proftpd's run-time scoreboard file (configured via the ScoreboardFile directive in proftpd.conf ). If proftpd's default directory has been changed via this directive, ftpcount must either be recompiled or this option must be used in order to find proftpd's scoreboard. -S,--server server-name Specify the ServerName for a specific virtual host. If used, ftpcount will only show the session count for the given virtual host. FILES
