Hi all,

I was just wondering if there is any best practice when you have a private Backend for GlusterFS ?

I also wanted to know various system values (like ulimit) you may have

Here is mine : 
# ulimit -a
core file size          (blocks, -c) 1
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) 1029408
max locked memory       (kbytes, -l) 64
max memory size         (kbytes, -m) 112008152
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes, -v) 107097200
file locks                      (-x) unlimited

vm.swappiness                                    =60 
vm.vfs_cache_pressure                        =100
vm.dirty_background_ratio                    =10
vm.dirty_ratio                                      =40
sys/block/<device>/queue/scheduler     = cfq     (ssd drive)
/sys/block/<device>/queue/nr_requests = 128
 /proc/sys/vm/page-cluster                   = 3
/proc/sys/net/ipv4/tcp_fin_timeout         =30
/proc/sys/net/ipv4/tcp_rmem                =4096    262144  4194304
/proc/sys/net/ipv4/tcp_wmem              =4096    262144  4194304
/proc/sys/net/ipv4/tcp_retries2             =15
/proc/sys/net/ipv4/tcp_keepalive_intvl   =75
