I suspect you meant "ulimit -a"?
ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
max nice (-e) 20
file size (blocks, -f) unlimited
pending signals (-i) unlimited
max locked memory (kbytes, -l) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 1024
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) unlimited
max rt priority (-r) unlimited
stack size (kbytes, -s) 8192
cpu time (seconds, -t) unlimited
max user processes (-u) unlimited
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
Just in case you did mean uname -a:
uname -a
Linux jupiter01 2.6.15.7-ubuntu1.060913 #1 SMP Wed Sep 13 15:21:26 EDT
2006 i686 GNU/Linux
The servers are Ubuntu 6.06.1, with a custom kernel for Lustre. They have
an old Fuse, not 2.6.3, but I suspect this is more of a glusterfsd issue
rather than a glusterfs issue. My third client does have FUSE 2.6.3, and
it also reports "Too many open files."
I Googled a bit and found someone else had written their own Fuse
filesystem and encountered the error. Someone suggested ulimit to remove
the limit, but he found it was a bug in his code where it was leaking open
directories.
Even if I can increase the limit, I still suspect it's a bug, and the new
limit would eventually be reached.
Thanks,
Brent
