Hi
I've suddenly lost access to some permanent cross-server shares.
I think this was following the Nov 5 new kernel, rather than the Centos version upgrade.
I don't see any difference to man mount.nfs

I have:-
[root at hs6 ~]# mount hs8:/data /sysback/hs8-data -v
mount: no type was given - I'll assume nfs because of the colon
mount: trying 172.26.0.8 prog 100003 vers 3 prot tcp port 2049
mount: trying 172.26.0.8 prog 100005 vers 3 prot udp port 735
mount: hs8:/data failed, reason given by server: Permission denied

Yet on hs8 the log shows:-
Nov 29 12:47:52 hs8 mountd[2255]: authenticated mount request from 172.26.0.6:617 for /data (/data)

No internal permissions have changed.
