Cannot mount vol0 after a "4a"

jpampel — Thu, 05 Jun 2025 07:20:06 GMT

Hi,

I am in the process of reprovisioning a 3020 filer. I ran through the whole 4a process, re-did the networking (/rc and /hosts), configured the RLM etc. That's all fine.

I remembered I had to re-install DOT when I could not open filerview.

So I am trying to mount it, and nothing I do is working. It's just shutting me down.

Here is the filer, i am checking on permissions...

names and ip's changed to protect the innocent..

Filer> exportfs -c Solaris /vol/vol0 root
exportfs: Solaris has root access to /vol/vol0
Filer> exportfs -c Solaris /vol/vol0 rw
exportfs: Solaris has rw access to /vol/vol0
Filer>

Here is that same unix host trying to "touch test" on /vol/vol0 and being told no way..

It's making it really hard to re-install since I cant get code on the filer..

Any suggestions?

Thanks in advance.

I have blogged the web way of Data ONTAP install @ http://communities.netapp.com/blogs/fitforpurpose/2009/06/19/installing-data-ontap-7g-the-easy-way, you can try this out.

Thanks

Daniel

To mount the root volume of filer on a host, make that host a trusted host, i.e you have to make entries in /etc/hosts for the admin host. else you can define admin by running setup command.

Try redoing the permission for the client in filerview or tpye exportsfs -a wait about a min and try again

Thanks to all for helpful suggestions.

Issue turned out to not be filer related - there was a NAT issue in the remote access device we were using so my IP was incorrect when I hit the filer. The ACL's were WAD.

If I could have connected I could have gotten a trace off it and seen this immediately.

What I did instead was the cheap and easy (in hindsight!) solution: Log in via SSH and fatfinger the password - and then check the log. Your source IP shows up in the log.

Cheers - JP
