Finally, I've changed the configuration to the following:
##
### MDS
##
[mds]
mds_cache_memory_limit = 792723456
mds_bal_mode = 1
##
### Client
##
[client]
client_cache_size = 32768
client_mount_timeout = 30
client_oc_max_obijects = 20000
client_oc_size = 1048576000
client_permissions = false
client_quota = false
rbd_cache = true
rbd_cache_size = 671088640
I've disabled client_permissions and client_quota because the cluster is
only for the webpage and the network is isolated, so it don't need to check
the permissions every time, and I've disabled the quota check because there
is no quota on this cluster.
This will lower the petitions to MDS and CPU usage, right?
