On a Dell Poweredge T620 with Xeon hexacore processor, i notice that there are 14 extraneous processes for the jfs filesystem. On another server, there are similar processes for the xfs filesystem as well.
Though they don't cause any problem or significant load, i would like to get rid of these processes since i use neither jfs nor xfs.
Here are the relevant parts of the ps ax output:
31611 ? S 0:00 [jfsIO]
31612 ? S 0:00 [jfsCommit]
31613 ? S 0:00 [jfsCommit]
31614 ? S 0:00 [jfsCommit]
31615 ? S 0:00 [jfsCommit]
31616 ? S 0:00 [jfsCommit]
31617 ? S 0:00 [jfsCommit]
31618 ? S 0:00 [jfsCommit]
31619 ? S 0:00 [jfsCommit]
31620 ? S 0:00 [jfsCommit]
31621 ? S 0:00 [jfsCommit]
31622 ? S 0:00 [jfsCommit]
31623 ? S 0:00 [jfsCommit]
31624 ? S 0:00 [jfsSync]
