JFS chkdsk options on OS/2

As most of us OS/2 users know by now, IBM never fully finished fleshing out the original port of JFS to OS/2 from AIX. This is especially true for the documentation of the (few) utilities related to JFS (see my other post concerning the JFS service log).


Archiving JFS service logs on OS/2

Quick refresher:

IBM ported JFS from AIX to OS/2 for release with Warp Server for e-Business in 1999 1, and it ultimately made its way into the Warp 4 client a few months later. Anecdotal evidence (read: my own personal conversations with people who know) says that the port was pretty rough around the edges, and much of the utilities were left in barely-usable condition (many people to this day shy away from defragfs on OS/2). The hope (or so I'm told) was that a third party 2 would develop a better set of tools at some point down the road.
