Bug Description
[Impact]
Without this nofile limit fix, large ceph cluster fails to start or stops handling requests.
[Fix]
Ceph upstream applied a new nofile limit(10x) to Giant+ releases (vivid in Ubuntu repo).
https:/
[Test case]
Check that new nofile ulimit is properly applied as 32768 -> 327680:
$ cat /proc/$(pgrep -n ceph-osd)/limits | grep 'Max open files'
[Regression Potential]
minimal,
If we set 1M nofile ulimit, the daemon will fail to start due to the default fs.nr_open value. However this time, we will apply 0.3M which should not cause troubles.
