[Gluster-devel] Rsync failure problem

[skimber]

Thanks for the responses.

It turned out that the issue was with the disk in one of the clients.  Using
the other client machine it appears to be working fine, although it does
seem very slow.

An ls -l on a directory containing about 150 files took > 5 mins and the
rsync will only go at a rate of roughly one file every 3 seconds, average
size 30 to 50Kb.

If I do the rsync to the client's local HD instead it's many files per
second.

I have tried adding the following to the end of the client config from my
original post but it doesn't appear to have made any noticable difference:

volume readahead
  type performance/read-ahead
  option page-size 128kB        # 256KB is the default option
  option page-count 4           # 2 is default option
  option force-atime-update off # default is off
  subvolumes unify
end-volume

volume writebehind
  type performance/write-behind
  option aggregate-size 1MB # default is 0bytes
  option flush-behind on    # default is 'off'
  subvolumes readahead
end-volume

volume io-cache
  type performance/io-cache
  option cache-size 64MB             # default is 32MB
  option page-size 1MB               # 128KB is default option
  option priority *:0                # default is '*:0'
  option force-revalidate-timeout 2  # default is 1
  subvolumes writebehind
end-volume


Can anyone tell me if I have done this correctly and/or suggest anything
else I can do to fix this performance issue?

Thanks

Simon
