Cannot find /nas/sbin
I have been having problems with my backups, which used to work, and while troubleshooting today I ran across an article saying to make sure that SnapSure is enabled. So, I SSH'd into my Celerra and tried to issue the necessary commands only to always come back with file not found errors. It turns out that /nas/sbin is not mounted from what I can tell, so I can't do anything at all. Also, the web interface on the control station is not coming up, and when I login via SSH I get a big warning saying that NAS Services are not running.
We did have a power outage a couple weeks ago that took everything offline and my CIFS shares never came back online after that. After a couple hours with support they got my CIFS back up and running, but I guess they didn't get everything sorted out 100%.
How can I mount /nas/sbin, and what can I do after that to get everything up and running properly? I would really prefer not to have to take my CIFS shares offline at all as I have users actively accessing data all weekend on a high priority project with a certain global impact in a large body of water (dont think I need to say anymore!)
Thanks for any help!

Yes, the NAS database and NAS services are only ever active on the currently active control station.
When you login as nasadmin you should get a reminder that NAS services aren’t running
For simplicity you can actually create an IP alias that will always point to the currently active CS

i know this thread is old...if it's still active i'm wondering if the issue was ever resolved? i'm in the similar situation where the nas services are not running on the control station. is there a way to manually turn on these services?

Manually – just reboot the CS after you checked that the data movers are running properly

It typically means either
- You are on the standby control station
- Your system didn’t boot correctly – i.e. data movers weren’t up when the CS started
- You have an installation problem

Thanks for your reply Rainer! but, i'm on the standby control station. there was a power outage. afterwards, the primary control station is non-responsive (in the back there are just red led lights and the management port no longer responds (ip or serial)). so i wanted to manually switch over control to the secondary using ./cs_standby -takeover, but it just gives me an error that the NAS serives are not running on slot_0. I'm trying the bootup sequence again, see if that helps.

turns out my primary control station is bad (probably a hard drive failure as the HD led in the front never blinks). The ./cs_standby -takeover command never worked for me but I was able to force the secondary to switch over to primary doing the following:
>mount /nas
>cd /nas/sbin
>./setup_slot -init 0
this initialized slot 0 and setup slot_1 as the primary.
>./getreason
0 - slot_0 reset
10 - slot_1 primary control station
5 - slot_2 contacted
5 - slot_3 contacted
then i ran
> service nas start
and after a few minutes all was good.
