| 135 | In BLFS we assume that nfs v3 will be used. If the
|
---|
| 136 | <emphasis>server</emphasis> offers nfs v4 (for linux, CONFIG_NFSD_V4)
|
---|
| 137 | then auto-negotiation for v3 will fail and you will need to add
|
---|
| 138 | <literal>nfsver=3</literal> to the mount options. This also applies
|
---|
| 139 | if that option is enabled in the <emphasis>client's</emphasis> kernel,
|
---|
| 140 | for example in a distro trying to mount from a BLFS v3 server.

| 144 | <literal>nfsver=3</literal> is still beneficial because it prevents an
