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?
