No such file here, not even the directory. It is "/var/lib/nfs/etab" here.

But no, the version is not there:

/data/hoard_1	192.168.2.0/24(rw,sync,wdelay,hide,nocrossmnt,secure,no_root_squash,no_all_squash,subtree_check,secure_locks,acl,no_pnfs,fsid=10,anonuid=65534,anongid=65534,sec=sys,rw,secure,no_root_squash,no_all_squash)

As I said, I restart the server. Or perhaps, "exportfs -r".


Actually, I have a server machine with external disks, and they are just mounted and exported properly, no issues.

Except that if the disk is not mounted, nfs doesn't start.
