how to get pools to BTRS

[gwaitsi]

I am looking to move off truenas to rockstor because not being able to get a backup on usb to put in the firesafe just leaves me too uncomfortable.
Not to mention my lack of experience with ZFS the strange import messages i receive on boot since moving to v12.

is it possible to mount BTRFS drive to be able to transfer the data. I don't have a 2nd system i can use.

If you mean BTRFS - simple answer: no.

If you want to backup your pool on USB, just mount the USB disk on your computer and then copy the data through the network with your favorite backup tool. (for example rsync)
In this case, you can use the filesystem that you want on your USB disk.

It is not only backing up the pools (which was certainly more convenient in OMV with USB3.0 plug-n-play - stick the dive in on the nas box, and off she goes) but also, backing up the jails and system for recovery.

and more specifically the errors i am getting since upgrading.

11.3U5 - > 12.1 Disk Errors? Importanting disks after every reboot

Since upgrading to 12.x I am getting what looks like to be a load of errors on boot for all drives. Is this normal, or something I need to take care of? Why does it keep saying importing the pools, when I have been using this in 11.3U2-5 without these messages. I note, these messages appear on...

long story short, I am feeling out of depth and probably need to go back to an environment where I am more comfortable with.

Is it possible to install OpenZFS on linux and simply be able to plug a disk (assuming non-spanning pools) in?
If so, could I not then sync the pool (my are kept to single discs) with a usb drive with zfs and just plug that into linux to be able to access my data?

A GPT partitioned disk with a single disk vdev on it should definitely be transportable from FreeBSD to Linux and vice versa.
Hope is that with more adoption of OpenZFS (Mac OS, Windows) we will finally get a truly interchangeable filesystem that is not FAT32.

Patrick, do you know why i keep getting these import message / errors on every boot? this is only occurring since upgrading from 11.3U5

I've done this myself, but only as a test. It worked as expected on the latest version of Manjaro which has ZFS version 2.0+ on its official repositories. I did not try it with native encryption, but I don't see why it wouldn't work.

Code:

$ zfs --version
zfs-2.0.3-1
zfs-kmod-2.0.3-1

$ uname -r
5.10.19-1-MANJARO

$ pacman -Qs zfs
linux-latest-zfs 5.10-1
linux510-zfs 2.0.3-5
zfs-utils 2.0.3-1

Edit: cleaned up output for relevancy

I made sure I could mount and access the ZFS datasets on the external drive (single drive, non-spanning pool).

However, I used a script/command to send/recv the datasets from my TrueNAS system to the externally attached USB drive; I did not use any official GUI method.

Please open a new thread for that. This one is about BTRFS support if I remember correctly. And no, no idea.
