graywolf Posted July 10, 2013 Share Posted July 10, 2013 unRaid version: 5.0-beta11 VM Trying to do the following. Not getting OOM but would like to have it in place just in case: pgrep -f "/usr/local/sbin/emhttp" | while read PID; do echo -1000 > /proc/$PID/oom_adj; done Gives me: root@Tower:/root -> pgrep -f "/usr/local/sbin/emhttp" | while read PID; do echo -1000 > /proc/$PID/oom_adj; done -bash: echo: write error: Invalid argument So stepping thru it: root@Tower:/root -> pgrep -f "/usr/local/sbin/emhttp" | while read PID; do echo $PID; done 1378 root@Tower:/root -> ls -l /proc/ | grep 1378 dr-xr-xr-x 6 root root 0 2013-07-10 09:16 1378/ dr-xr-xr-x 6 root root 0 2013-07-10 11:02 13785/ dr-xr-xr-x 6 root root 0 2013-07-10 11:00 13786/ root@Tower:/root -> ls -l /proc/1378 total 0 -r-------- 1 root root 0 2013-07-10 11:08 auxv --w------- 1 root root 0 2013-07-10 11:08 clear_refs -r--r--r-- 1 root root 0 2013-07-10 11:08 cmdline -rw-r--r-- 1 root root 0 2013-07-10 11:08 comm -rw-r--r-- 1 root root 0 2013-07-10 11:08 coredump_filter lrwxrwxrwx 1 root root 0 2013-07-10 11:08 cwd -> // -r-------- 1 root root 0 2013-07-10 11:08 environ lrwxrwxrwx 1 root root 0 2013-07-10 11:08 exe -> /usr/local/sbin/emhttp* dr-x------ 2 root root 0 2013-07-10 11:08 fd/ dr-x------ 2 root root 0 2013-07-10 11:08 fdinfo/ -r--r--r-- 1 root root 0 2013-07-10 11:08 limits -r--r--r-- 1 root root 0 2013-07-10 11:08 maps -rw------- 1 root root 0 2013-07-10 11:08 mem -r--r--r-- 1 root root 0 2013-07-10 11:08 mountinfo -r--r--r-- 1 root root 0 2013-07-10 11:08 mounts -r-------- 1 root root 0 2013-07-10 11:08 mountstats dr-xr-xr-x 4 root root 0 2013-07-10 11:08 net/ -rw-r--r-- 1 root root 0 2013-07-10 11:08 oom_adj -r--r--r-- 1 root root 0 2013-07-10 11:08 oom_score -rw-r--r-- 1 root root 0 2013-07-10 11:08 oom_score_adj -r-------- 1 root root 0 2013-07-10 11:08 pagemap -r-------- 1 root root 0 2013-07-10 11:08 personality lrwxrwxrwx 1 root root 0 2013-07-10 11:08 root -> // -r--r--r-- 1 root root 0 2013-07-10 11:08 smaps -r--r--r-- 1 root root 0 2013-07-10 11:08 stat -r--r--r-- 1 root root 0 2013-07-10 11:08 statm -r--r--r-- 1 root root 0 2013-07-10 11:08 status -r-------- 1 root root 0 2013-07-10 11:08 syscall dr-xr-xr-x 4 root root 0 2013-07-10 11:02 task/ -r--r--r-- 1 root root 0 2013-07-10 11:08 wchan root@Tower:/root -> cat /proc/1378/oom_adj 0 root@Tower:/root -> echo -1000 -1000 root@Tower:/root -> echo -1000 > /proc/1378/oom_adj -bash: echo: write error: Invalid argument root@Tower:/root -> Link to comment
graywolf Posted July 11, 2013 Author Share Posted July 11, 2013 No one? Am I doing something wrong or can you no longer modify emhttp so that it is better protected from OOM situations? Link to comment
Joe L. Posted July 12, 2013 Share Posted July 12, 2013 No one? Am I doing something wrong or can you no longer modify emhttp so that it is better protected from OOM situations? You ARE doing something wrong. The /proc parameter changed from when in the 4.7 series. It is no longer named oom_adj in the newer kernels. It is named oom_score_adj pgrep -f "/usr/local/sbin/emhttp" | while read PID; do echo -1000 > /proc/$PID/oom_score_adj; done Link to comment
graywolf Posted July 12, 2013 Author Share Posted July 12, 2013 Thanks JoeL. Works like a charm now. Greatly appreciate your assistance Link to comment
electron286 Posted July 12, 2013 Share Posted July 12, 2013 With the change in name from oom_adj to oom_score_adj was anything else changed, is the functioing all the same? Link to comment
Joe L. Posted July 13, 2013 Share Posted July 13, 2013 With the change in name from oom_adj to oom_score_adj was anything else changed, is the functioing all the same? Yes. The value set permitted changed from +-17 to +-1000 Link to comment
doorunrun Posted July 13, 2013 Share Posted July 13, 2013 Is there any reason to not use this with 5.0rc16c? Thanks! Link to comment
Joe L. Posted July 13, 2013 Share Posted July 13, 2013 Is there any reason to not use this with 5.0rc16c? Thanks! I can't think of any... especially if you are going to be running any add-ons that might malfunction and accidentally use up all available memory. Link to comment
