Hello Vasily, you didn't read the docs for nfs v4 on linux, did you? The filesystem-type for nfs v4 is nfs4 and not nfs. I think this is because v4 is provided by a completely different filesystem driver independent of the v2 and v3 implementation. I think your fstab entry should probably look like this: host:/path/to/export /misc/whatever nfs4 rw,hard,intr,exec,acl Regards, Andreas Rogge Am Montag, den 05.02.2007, 16:55 -0500 schrieb Vasiliy Boulytchev: > Ladies and Gents, > > Having a rough time with nfsv4...
