[Gluster-devel] Problems with ioc again

[Anand Avati]

Dan,
  I have a vague memory about giving a custom patch for io-cache. Was that
you? Can you mail me the diff and I can answer your question..

I'd love to use 1.4rc4 but are there any issues in it that would effect me?
I have 4 glusterfs servers, each with 2gbit ethernet (bonded), provididing
sustained 8gbit/s to 33 client nodes. Below is my entire config file. If you
see anything in there using a system that is either buggy or non-optimal in
1.4rc4, or would be difficult to upgrade, please let me know. If not, I can
possibly upgrade.

Below is my current config file. The one I was using when gluster was using
all memory is identical except for 'cache-size' was changed to 4096MB and
'page-size' was changed to 512KB.
