Subject Re: SSVM NFS Access Denied Problems
Date Sun, 13 Nov 2016 23:13:49 GMT
Hi Asai,

I don’t have much experience with Nas4Free – so I can’t comment – however I do know
the CloudStack / hypervisor / SSVM requirements are fairly straight forward, so it sounds
like your NAS appliance is possibly to blame.

A few things to try:

- Try to manually mount a NFS share from your management server (as already mentioned by Sergey).
If you can mount the share make sure you can read/write.
- Try to manually mount the same NFS share from your hypervisors. Again try to read/wite.
- Log in to your SSVM and run /usr/local/cloud/systemvm-ssvm-check.sh.

Between these three it will tell you if you have any NFS access at all. If you don’t then
sounds like you need to spend some more time on your NAS4Free box – and in this case I would
just concentrate on a single client – e.g. the management server – until you have worked
out what the issue is. Once resolved you can move back to testing with your hypervisors and
CloudStack. So – in other words – don’t waste your time trying to troubleshoot this
through CloudStack until you have the underlying connectivity and access sorted.

The other thing is obviously to configure your NAS4Free box with as verbose logging as possible
and check why it denies access.

Regards,
Dag Sonstebo

    Thanks Dag,
    
    The thing that's really got me right now is even if I set the allowed network subnet to
/16 which contains all necessary subnets I get access denied.  Even when I mount from the
CLI as root I get access denied...  Maybe it's a NAS4Free bug? NAS4Free runs on FreeBSD...
Maybe there's some subtle incompatibility?
