Yes, but if you use v3 or v4 it's larger than you care about. > Or is that strictly a > matter of the filesystem type being exported (ext3, xfs, lustre, gfs, > whatever)? That also matters. You need to have a server OS which supports large block devices, and the filesystem needs to support it also. Obviously, XFS does (except it can't export more than 2^32 inodes currently). > Does it matter if you're using nfs v2/v3/v4? Yes. Don't use NFSv2. > Does the > kernel version matter? How about 32 bit vs 64 bit platforms (especially > interested in whether an opteron or linux ppc would help)? This comes down to large block device support. You need to use 2.6 or apply the LBD patch to 2.4. > Is linux NFS on 64 bit platforms stable? Yes. Our sales staff will be happy to sell you one, and as many TB of disk as you can afford.
