Hi,
As of kernel 2.4.5 I'm getting two symptoms:
| bash$ w | 11:27:35 up 1 day, 21:24, 16 users, load average: 0.06, 0.04, 0.00 | USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT | bash$ (note lack of actual data)
and in top:
| 11:42:22 up 1 day, 21:39, 12 users, load average: 0.08, 0.04, 0.01 | 0 processes: 0 sleeping, 0 running, 0 zombie, 0 stopped | CPU states: 0.2% user, 0.4% system, 0.0% nice, 99.4% idle | Mem: 188756K total, 175548K used, 13208K free, 26508K buffers | Swap: 257000K total, 19020K used, 237980K free, 98708K cached | | PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND | | | |
(tends to 100.0% idle over time - refresh interval of 3s.)
In either case, this sits around for about 10s and then normal service is resumed. During outages, the rest of the box behaves as normal.
I was informed this is due to a `locking issue' that only ReiserFS stumbled upon (the above happened most times when I write to /home or /var/log, both of which are ReiserFS), and that it was fixed in 2.4.6 (pre3). I'm now running 2.4.7-pre3 and it *still* occurs, although not as frequently as before (was roughly 2 out of every 3 writes to a reiser partition; now less than predictable).
Data: Debian/Testing updated daily. Filesystems used:
/dev/hda1 on / type xfs (rw) /dev/hda4 on /var/spool type xfs (rw,noexec,nosuid,nodev) /dev/hda5 on /var type reiserfs (rw,nosuid,nodev,noatime) /dev/hda7 on /usr/local type reiserfs (rw) /dev/hda8 on /home type reiserfs (rw,nosuid,nodev,noatime)
If anyone else has experienced this and/or has clues what's going wrong, I'd be grateful.
TIA,
