Journaling vs. Softupdates
Hi all, This is addressed in the FAQ to some extent, but that answer seems incomplete. Apparently one of the Google Summer of Code projects is to add journaling to UFS. When it already has softupdates, why? I've seen benchmarks that seem to indicate that softupdates performs as well or better in most cases, though I have nothing on hand to substantiate that. I thought the only real disadvantages of softupdates were: - harder to code and implement (though this is already done, so should not be an issue) - sometimes deleting files does not free space right away Possibility of data loss, I'm guessing, is the same with either. Filesystem corruption is similarly very unlikely. So why the change? Thanks in advance for any answers.

tar ssh: strange gzip error message?
Hi all, If I want to copy a bunch of files over ssh without extra servers, it's easy enough to use the following command: [EMAIL PROTECTED] ssh [EMAIL PROTECTED] cd /directory/to/copy tar -cvf - * | tar -xf - -C . This works without complaint. However, when I change the options passed to tar, adding gzip compression on one end and decompression on the other: [EMAIL PROTECTED] ssh [EMAIL PROTECTED] cd /directory/to/copy tar -cvzf - * | tar -xzf - -C . I get this error message: gzip: stdin: decompression OK, trailing garbage ignored tar: Child died with signal 13 tar: Error exit delayed from previous errors Is my method wrong? It appears that the files transferred just fine, but I'm still curious as to what's going on. Thanks in advance to any replies.

Recursive renice?
Hi all, I'm curious whether there's an easy way to renice(8) a process and all of its children in one simple command. For example, I might start a recursive make, which spawns lots of processes, and want them all to change priority at once. The command I want is this: renice +10 -r process-ID Except for the fact that -r is not a valid flag. The pstree utility, in the ports, seems like it might be a good start to hack this functionality in. I searched google for recursive renice and found someone had made a sed script, but it's for linux, where the pstree output is different. Here's some example pstree output: | \-+- 14187 zevt gmake | \-+- 14189 zevt gmake all-recursive | \-+- 14190 zevt /bin/sh -c set fnord ; | \-+- 14807 zevt /bin/sh -c set fnord ; [etc.] Google result that's relevant: http://mail.gnu.org/archive/html/bug-coreutils/2003-10/msg00033.html Any hints?

Re: / is filling up
The usual solution I use would be (starting in the root directory) du -kx | sort -n. The x flag prevents crossing partitions when doing the recursive analysis that du is meant to do, while the k flag makes the output in kilobytes. I like this command enough that I have a shortcut to it in my .bashrc called dk. Check the man page for du for other options if you want. Hope this helps. Zev My / partition is getting pretty full, 92%. Usually the culprit is something I'm not rotating in /var/log, but that's not the case this time. Does anyone have any suggestions to find out where this is? I'm guessing it's probably something using ls and sort but I'll be damned if I can put something together that helps this problem.
