[Gluster-devel] memory usage (client)

[Harris Landgarten]

Rheas,

My setup is very similar to yours but I am not using io-threads on the client (only on servers) and I have 2 bricks. This is my top

 4522 root      15   0 14812 5420  848 S  0.0  0.3   0:11.03 glusterfs

Quite a difference.

Harris

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
