I'm exporting some files (>10GB files) via NFS from a 2.6.23.1-kernel,
SuSE system, and mounting on another (same kernel).
All of my files >2GB (not exactly sure if break point is at 2 or 4GB's,
all the large files I look at on the source are over 20G) give stat
errors over NFS. Both kernels have nfs v4 as well as v3 compiled in.
I've heard v2 has a 2GB limit, but v3 should be fine. Have been
playing with tags 'nfsvers=[3 or 4]' in the /etc/exports file, but
exports doesn't recognize nfsver=4, and gives out of range error message
on nfsver=3 saying allowed values are Min=1, Max=2. !? I'm not sure if
it is using V3 or 4 (am trying to use 'tcp' tag as well, but not using
the tcp isn't the prob, as that was the default before I started looking
at this problem.
I don't have problems over CIFS from a windows box, but so far, limited
benchmarks show better linux-to-linux perf over NFS (assuming I
stay under 2GB files, but that's sorta limiting...).
Underlying filesystem on the server box is XFS -- been serving Win
clients for years, so haven't had alot of experience using NFS, recently,
since >2G files became fairly common place.
Any ideas how I could be serving up NFS and not >2GB files with a modern
kernel and client? *scratching head* ;^?
Thanks,
Linda
