Debug failed mount: No such file or directory

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

> 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.

What am I missing? Is there anything like "exportfs -r" that I have to run?

Not sure if I missed it…how about

Which export policy is applied to the svm root volume? For nfs clients, they must be able to access each junction path including / (svm root). I do not see that on the showmount command and I would expect it

and how about this

Vserver nfs show -fields v3,v4.0,v4.1

plus the

volume show -fields policy -volume svm-root

Ah, yes, sorry, concerning showmount I pasted only the line about my affected share (since there is a big amount of them

> showmount -e vrc01n01b Export list for vrc01n01b: /proj_rfip_hki (everyone) / (everyone)

> vserver nfs show -fields v3,v4.0,v4.1 vserver v3 v4.0 v4.1 ------- ------- -------- -------- vrcv01a enabled disabled disabled

> volume show -fields policy -volume vrcv01a_rootvol vserver volume policy ------- --------------- ------- vrcv01a vrcv01a_rootvol default

Then I have also

> volume show -fields policy -nodes vrc01n01b vserver volume policy --------- ------ ------ vrc01n01b vol0 - ...

Now there are many volumes, of course, but I don't recognize what this vol0 is

vol0 is an moot volume. No data should ever be there

try this temporarily

mount -v -o vers=3 vrc01n01b:/ /tmp_path that should work. Then try to access the path you are looking for on the temp location. You may get better diagnostic messages.

also, it appears that the “string” path you are supplying to mount is not matching the “string” path on the Netapp. Maybe there is a space somehow in the name on the Netapp?

Re: Debug failed mount: No such file or directory

PatrikOsgnach — Sat, 21 Dec 2024 15:29:40 GMT

Good idea

# mount -v -o vers=3 vrc01n01b:/ /tmp/hki mount.nfs: timeout set for Sat Dec 21 16:28:17 2024 mount.nfs: trying text-based options 'vers=3,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 # ls -l /tmp/hki/proj_rfip_hki ls: cannot access '/tmp/hki/proj_rfip_hki': No such file or directory

Seems there is no directory for the mountpoint

Re: Debug failed mount: No such file or directory

TMACMD — Sat, 21 Dec 2024 15:44:57 GMT

Just do an ls of the temp directory and see what’s there. Like I said maybe there is a mismatch of what you think versus what actually is.

still looks like the directory make you are trying to look for isn’t there. What about

vol show

don’t add anything. Just find your volume and then paste the output. Wondering if the volume is online, read/write

Re: Debug failed mount: No such file or directory

PatrikOsgnach — Sat, 21 Dec 2024 15:45:40 GMT

I did and I see directories for all the other volumes

TMACMD — Sat, 21 Dec 2024 15:49:55 GMT

Which is why you should see if the volume is online and read/write capable from the basic vol show output

What is the volume security on tries volume? There is a possibility if it is ntfs that may be why its not showing

Another thought. Network lif.
net int show -vserver xx -lif lifname -fields service-policy

then

net int service-policy show -vserver xx -policy fromabove
