How to retrieve data from old disks?

[DenoBeno]

Hi, everyone,

I've been using FreeNAS few years ago, but I haven't done anything with it for 3+ years and forgot like 99% of what I learned back then.
Now I need to access the data from a FreeNAS 9.2 system that has been sitting disabled for a few years.

Unfortunately, the USB boot disk didn't work and so I made a new one, rebooted and tried "auto import volume". Not sure if that did any good though. Here is what I can see on the web interface:

1) under storage/active volumes /view discs - nothing shown (?)
2) However, on the left-hand side, under volumes there is /mnt/vol01 with the whole tree, including the /mnt/vol01/media that I am most interested in.

Using the console, I can see the following:

# zfs|grep media
vol01/media 231G 662G 205G /mnt/vol01/media
# mount |grep media
vol01/media on /mnt/vol01/media (zfs, local, nfsv4acls)
# ls /mnt/vol01/media
- nothing returned.

So, it would seem that I have 231GB of data mounted on /mnt/vol01/media but none of it is showing. What do I need to do to access this data again?

I'm looking at the similar thread on https://forum.level1techs.com/t/freenas-my-usb-stick-died-need-help-restoring-my-volumes/117690/4 to save some time...

Oh, wow - just needed to reboot and the data is available now.

Cool.
