Hello everyone, Currently one of the production gluster nodes is consuming a lot of memory, in particular the gluster NFS process makes great use of SWAP memory and does not release it. It happens to someone else? # for file in /proc/*/status ; do awk '/VmSwap|Name|Pid/{printf $2 " " $3}END{ print ""}' $file; done | sort -k 5 -n -r | less glusterfs 16818 1 0 5283484 kB glusterfs 16826 1 0 434184 kB glusterfsd 14648 1 0 63500 kB # ps aux | grep 16818 root 16818 48.1 61.7 27419204 20265168 ? Ssl Feb27 39412:28 /usr/sbin/glusterfs -s localhost --volfile-id gluster/nfs -p /var/lib/glusterd/nfs/run/nfs.pid -l /var/log/glusterfs/nfs.log -S /var/run/gluster/4e5989084b357ad0d2530754e086bd73.socket # free -m total used free shared buffers cached Mem: 32073 31710 362 0 0 4291 -/+ buffers/cache: 27418 4655 Swap: 7247 7247 0 The gluster version is 3.7.1-16 under RHEL 6.7 Launching the following commands does not help, as the swap memory is re-occupied in full over time. # sync # echo 3 > /proc/sys/vm/drop_caches The swappiness value is currently 60. # sysctl -a | grep swapp vm.swappiness = 60 Any idea or similar case? Thanks. Greetings, Jose Antonio Vico Palomino |
