Upgrading, and Pool Manager, and Snapshots - Oh My!

[aahzinfotech]

We've been using FreeNAS for several years and upgraded to TrueNAS a couple versions ago. Under FreeNAS, I had set up snapshots for a specific folder and it was set-and-forget. We didn't have any problems. We are at version TrueNAS-12.0-U4.

When I went to check out the snapshot history yesterday, I noticed that the only pool with snapshots was the iocage pool. I know I had created another pool previously, but the Pool Manager only shows the following: > pool > iocage and nothing else. I was hoping to get snapshots of > pool > second.folder. Yikes!

A bit of forum searching led me to realize that I need to create a new pool, but am quite unsure how to do that since my attempt to do so shows no available disks. And I'm afraid that to do so I may have to restart from scratch if I am determined to have snapshots.

This being the case, what or how would you recommend I go about getting this set back up?

Check the output of the following commands from the shell:

# zpool list
# zpool status

Do you still only see a single pool?

Hello Kris, thanks for responding. These are the results I'm showing:

So you have a 'pool1' on this system, it appears intact. If you check /mnt/pool1 do you see your directories / files? It may just be that you don't have snapshots taking place...

 

[aahzinfotech]

Yes, the secondary directory (named PD) and files are there. In fact, I can access the files from other computers. When I attempted, however, to set up a new snapshot, I am not allowed to choose a dataset other than pool1 or pool1/iocage/...

And it is entirely possible I'm not understanding the snapshots since there is one set up for pool1 already. The snapshots just seem to be too small to include the PD directory. Snapshots on some days are using 2.66 MiB and referencing approximately 11.45 TiB. But there should have been several GiB of changes going on.

In researching a bit further, I believe that I may have jumped the gun. I did find one or two snapshots that looked correct. This issue can be marked as closed and resolved. It was my misunderstand. Thank you!
