[Gluster-users] PageCache in Gluster Fuse and NFS clients

[Behrooz Shafiee]

Hello all,

 I am a graduate student at University of Waterloo and working on
filesystem. I have two questions about GlusterFS that I will appreciate if
anyone can comment about.

First, does GlusterFS FUSE client bypass Linux page cache mechanism(mount
with -o direct_io)? I have a machine with 64 GB of memory and when I write
a about 30GB of data into that machine (less than available memory) and
read it again, I see the reads are server through network, even though
those file could/are in the Linux page cache memory. It seems that's the
case both for NFS and FUSE clients.

My second question is about FS-Cache and if GlusterFS does inode tree cache
on its FUSE clients or not. I know it exist in NFS but is the NFS client of
GlusterFS same as regular NFS?

Thanks in advance,
