New ps feature -R
master now has a new feature to /bin/ps, -R, which sub-sorts by parent/child association and follows the chain in the output, indenting the command to make it obvious. Sample usage: ps axlR This is a pretty cool feature I think. I had written something similar 15 years ago and really began to miss it once I started doing parallel pkgsrc bulkbuild tests. -Matt Matthew Dillon

Re: How to tell where/how space is used?
Not to mention the fact that I just upped the minimum UNDO/REDO fifo size to 500M to help deal with an overflow issue. I may reduce the minimum to 300MB, but 100MB is just too small since most systems these days have at least 1GB of ram and on-media fifo use under stress tends to be related to the amount of ram on the box. HAMMER is not designed to be run on 2G partitions. When it says that 50G is the minimum it really means it. You can get away with smaller sizes with care, e.g. I run HAMMER just fine on a 40G SSD, but I wouldn't go much below that. For small partitions, UFS is just fine. UFS's fsck runs in just a few seconds on filesystems that small. -Matt
