Hi List, Here is part of /etc/init.d/ceph script: case "$command" in start) # Increase max_open_files, if the configuration calls for it. get_conf max_open_files "8192" "max open files" if [ $max_open_files != "0" ]; then # Note: Don't try to do math with these numbers, because POSIX shells # can't do 64-bit math (natively). Just treat them as strings. cur=`ulimit -n` if [ "x$max_open_files" != "x$cur" ]; then Line253: ulimit -n $max_open_files fi fi
When using with -a option, for **remote** osd , this script also run ulimit on **local**, and results in ulimit -n didn't change in remote nodes. I think the Line 253 shoud use do_cmd instead of run directly,also line 251. Here is the output of local osd daemon's limits: root@ceph-4:~# cat /proc/13131/limits | grep file Max file size unlimited unlimited bytes Max core file size unlimited unlimited bytes Max open files 131072 131072 files Max file locks unlimited unlimited locks Here is a remote one: root@snb-15:~# cat /proc/23709/limits | grep file Max file size unlimited unlimited bytes Max core file size unlimited unlimited bytes Max open files 1024 4096 files Max file locks unlimited unlimited locks Xiaoxi -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
