Hello list,
I'm currently experimenting with autofs on SuSE 11.1 rc1 -autofs-5.0.3-82.19 Around the 1024th mount, autofs hangs and the machine needs a reboot -f. I have here >2000 mount points which usually look like this: /homes/vogt0001 --fstype=bind :/net/fsA/home/user/vogt0001 /homes/vogt0002 --fstype=bind :/net/fsB/home/user/vogt0002 [..] /homes/vogt2000 --fstype=bind :/net/fsC/home/user/vogt2000 Further debugging revealed: pxe1:/home/demo1 # lsof -p <automount pid> [...] automount 5111 root 1022r DIR 0,228 0 13029 /u/itwm/hinojosa automount 5111 root 1023r DIR 0,561 0 13362 /u/itwm/andrejs automount 5111 root 1024r FIFO 0,7 0t0 26910 pipe The 1024 really looks like some limit, which is hit by the automount process. I checked ulimit -a: pxe1:/home/demo1 # ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 16117 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) 1717680 open files (-n) 4096 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 16117 virtual memory (kbytes, -v) 2455520 file locks (-x) unlimited The I checked ulimit under /proc: pxe1:/proc/5111 # cat limits Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited Max file size unlimited unlimited Max data size unlimited unlimited Max stack size 8388608 unlimited Max core file size unlimited unlimited Max resident set 1758904320 unlimited Max processes 16117 16117 Max open files 10240 10240 Max locked memory 65536 262144 Max address space 2514452480 unlimited Max file locks unlimited unlimited Max pending signals 16117 16117 Max msgqueue size 819200 819200 Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited ==> At least the Max file desc. looks ok, but somewho it hangs. Ah, the behavoir by autofs is: - It hangs on duing a mount operation: root 5111 0.0 0.1 97200 2936 pts/0 Sl+ 13:30 0:01 /usr/sbin/automount -d -f -t 600 -p /var/run/automount.pid -O ro root 9541 0.0 0.0 0 0 pts/0 Z+ 13:31 0:00 [mount] <defunct> stopping automount is not possible it needs a reboot -f I have search a bit for this problem, but found no solution yet. regards, Martin PS: I havent found a way to do it without bind mounts _______________________________________________ autofs mailing list autofs@linux.kernel.org http://linux.kernel.org/mailman/listinfo/autofs
