Hi all, I recently inherited an already configured AFF-A300. It already has some volumes, exported via NFS3 and they all work fine.   Today I tried to add a new volume via the Ontap system manager, but the mount fails:   # mount -v -t nfs vrc01n01b:/proj_rfip_hki /root/hki mount.nfs: timeout set for Fri Dec 20 19:21:29 2024 mount.nfs: trying text-based options 'vers=4,addr=10.217.231.21,clientaddr=10.217.231.88' mount.nfs: mount(2): Protocol not supported mount.nfs: trying text-based options 'addr=10.217.231.21' mount.nfs: prog 100003, trying vers=3, prot=6 mount.nfs: trying 10.217.231.21 prog 100003 vers 3 prot TCP port 2049 mount.nfs: prog 100005, trying vers=3, prot=17 mount.nfs: trying 10.217.231.21 prog 100005 vers 3 prot UDP port 635 mount.nfs: mount(2): No such file or directory mount.nfs: mounting vrc01n01b:/proj_rfip_hki failed, reason given by server: No such file or directory To check the most obvious reasons:  > volume show -vserver vrcv01a -fields volume,node,junction-path,policy vserver volume policy junction-path node ------- --------- ----------------------- ------------- --------- vrcv01a proj_rfip_hki clients /proj_rfip_hki vrc01n01b > vserver export-policy check-access -vserver vrcv01a -client-ip 10.217.231.88 -volume proj_rfip_hki -authentication-method sys -protocol nfs3 -access-type read Policy Policy Rule Security Path Policy Owner Owner Type Index Access Style -------------------- ---------- --------- ---------- ---- ---------- ---------- / default vrcv01a_rootvol volume 2 read unix /proj_rfip_hki clients proj_rfip_hki volume 2 read unix > export-policy access-cache show -node vrc01n01b -vserver vrcv01a -policy clients -address 10.217.231.88 Node: vrc01n01b Vserver: vrcv01a Policy Name: clients IP Address: 10.217.231.88 Access Cache Entry Flags: has-usable-data Result Code: 0 First Unresolved Rule Index: - Unresolved Clientmatch: - Number of Matched Policy Rules: 1 List of Matched Policy Rule Indexes: 2 Age of Entry: 741s Access Cache Entry Polarity: positive Time Elapsed since Last Use for Access Check: 407s Time Elapsed since Last Update Attempt: 741s Result of Last Update Attempt: 0 List of Client Match Strings: 10.217.231.0/25   From the client: # showmount -e vrc01n01b Export list for vrc01n01b: /proj_rfip_hki (everyone)   So, volume is there, it is mounted, it has an export policy and the client is allowed to mount.
