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.

This now mysteriously resolved after both servers have rebooted. The long delay is due to the importance of high availability over the nfs links.
