I am trying to determine the relation between the system imposed limit of
max FDs (4096 now) and
the Cache Inode HW Mark (100000 default).
In a test work load, I am getting errno 24 (too many open files) error
returned,
and here is our current settings.
15/05/2015 18:48:23 : epoch 5556a1e7 : OneBlox-0333 :
nfs-ganesha-12814[main] cache_inode_lru_pkginit :INODE LRU :INFO
:Attempting to increase soft limit from 1024 to hard limit of 4096
15/05/2015 18:48:23 : epoch 5556a1e7 : OneBlox-0333 :
nfs-ganesha-12814[main] cache_inode_lru_pkginit :INODE LRU :INFO :Setting
the system-imposed limit on FDs to 4096
I looked at the related code in Cache_inode but could not determine the
relationship between
the system limit and cache_inode or how many file FDs Ganesha will try to
open.
Any help is (1) What is the system limit to be set, given the default cache
inode HWmark?
(2) For the given system limit, what is the cache inode setting. We are
using Ganesha 2.1.
Regards.
