[Gluster-devel] memory usage (client)

[Rhesa Rozendaal]

Hi guys,

I've been trying to limit glusterfs' memory consumption, but so far not much 
luck.

here's a snapshot of my "top":
 6697 root      15   0  369m 295m  876 S   45 14.6   3:10.13 [glusterfs]

And it keeps growing, so I'm not sure where it'll settle. Is there anything I 
can do to keep it to around 100m?

Here's my current client config (having played a lot with thread-count, 
cache-size, etc):

volume ns
  type protocol/client
  option transport-type tcp/client
  option remote-host nfs-deb-03
  option remote-subvolume ns
end-volume

volume client01
  type protocol/client
  option transport-type tcp/client
  option remote-host nfs-deb-03
  option remote-subvolume brick01
end-volume

# snip client02 through client31

volume export
  type cluster/unify
  subvolumes client01 client02 client03 client31
  option namespace ns
  option scheduler alu
  option alu.limits.min-free-disk 1GB
  option alu.order 
disk-usage:read-usage:write-usage:open-files-usage:disk-speed-usage
end-volume

volume iothreads
  type performance/io-threads
  option thread-count 4
  option cache-size 16MB
  subvolumes export
end-volume

volume readahead
  type performance/read-ahead
  option page-size 4096
  option page-count 16
  subvolumes iothreads
end-volume

volume writeback
  type performance/write-behind
  option aggregate-size 131072
  option flush-behind on
  subvolumes readahead
end-volume
