I try to configure pcs storage but get an error:
[root@pcs ~]# pstorage -c mypcs set-attr -p -R / replicas=3:2 locality=2 max-host-replicas=1 connected to MDS#12 27-05-13 16:16:19.596 MDS#12 responds with error 13 (Peer did not respond or did not hold deadline)
MDS server is overloaded, probably it has lots of open files:
CLID LEASES READ WRITE RD_OPS WR_OPS FSYNCS IOLAT(ms) HOST 31339 2440831/ 38KB/s 250KB/s 0ops/s 28ops/s 13ops/s 0/23 10.10.100.21
lsof utility what files are opened and close or delete these files.
