Hi All,
This is my first post on the forum after I have been reading a lot (!) of very helpfull posts in building and configuring a TrueNAS system.
I moved from Netgear, to Synology, and now to TrueNAS. I am very happy with this system, often it feels too easy and intuïtive that it feels too good to be true.
Thanks in advance for the help.
In short, my problem is that I had setup my (offline) backup and it worked perfectly for me.
USB-HDD 16TB, Import Disk, Create Pool#2 with 2 datasets: 1 for Replicating Pool#1, and 1 for SMB-sharing to backup my Windows 10 System Image.
Then I powered down the USB-HDD to change the power-outlet. Then after Power On the USB-HDD, the problem arises "Pool UNAVAIL".
However, the SMB drive with the windows 10 system image still works, I can access the share. But I can't get the Pool#2 and the replicated Pool#1 to work, I don't see what I can do.
I have read a lot in the forum

- Don't use USB drives (link): I was doing this previously, and it kinda worked for my. My Netgear/Synology NAS did recognice the USB-HDD as a seperate device (NTFS/EXT4) formatted.
- How-to USB Drive as offline backup (link): I did it like this 'create a single-disk pool on the external USB drive'.
- Same usecase 'Manually (on-demand) replicating entire main pool to external USB drive' (link): learning something about offline/online drives
- How to Restore Disconnected Pool (link): I tried import existing Pool, can't see the Pool#2 to import
- Other source (link lost): I learned that one should put Pool offline before disconnecting USB-drive. If true, this would not fit my usecase
- Get the Pool back online
- Advise firstly how I could get this to work through the TrueNAS (comparable to Netgear/Synology)
- Secondly, advice, if this really should not be used like that, what I best could do next (I want a 'scheduled' offline backup, in case of emergency)
