How to reinstate a missing zfs share?

#1

Post by Northwinds » 23 Jan 2020 22:56

HI
I'm on
and just had a problem where I had to restore my config.

However it was a config from before I added a new zfs dataset share.

So this dataset is now missing from my nas gui and I can't access it from finder in osx - it shows as it would before but clicking on it tells me it can't be found.

But then if I SSH in via terminal it shows there.

So.... can I just add it as a new share again in the GUI?

I'm just worried it might over write or delete the data?

Any advice please?

Thanks!

Thanks for the reply!

I wasn't sure about your step 1 as all the disks are showing and 3 other zfs datasets on the pool in question are showing - it's just the fourth that's not.

Do I need to redo them all as in step 1?

I followed step 2 and under zfs>configuration>current the missing sgare is shown along with all the other datasets but while they're shown as "visible" that one is shown as "hidden"

So is there another way to "unhide" it or do I need to follow your step 1?

Many Thanks again!

Our recommendation is to perform the 2 steps in case of

- a hardware change or
- a system reconfiguration or
- after a configuration restore or
- after perfoming tasks on CLI or in Disks > ZFS > Pools > Tools.

The 2 steps only synchronize the stored configuration with the real-life configuration of your system. There will be no harm to your data, only the SMART configuration must be redone after step 1.
