Moving from OMV to Freenas Disaster

[Yorick]

why does it successfully mount on linux and receive all the data then?

Good question. "More data needed". Maybe it's Linux-LVM or linux-raid and not linux-data. That'd cause it. Or maybe there's a bug. Or maybe something else entirely.

This.

That being said:
With FreeNAS/TrueNAS (and BSD in general tbh) the advice is always "Stick with what works":
SATA or SAS, ZFS and Intel NICs

I would say this entire thread can be characterized as "FreeBSD is not Linux." At the end of the day, I have not tried to import Linux disks since I set up my first FreeNAS many years ago, so I can't really comment on that. FreeNAS documentation offers some suggestions about preparing Linux disks for import - I would start there. I would also check some FreeBSD sources to see if there are any utilities available that might be helpful.

One thing that is clear though, is that Linux supports a wider array of hardware options than does FreeBSD. One cannot automatically assume that something which works in Linux will also work in FreeBSD.

Out of curiosity. I've just imported an ext2 formatted drive into FreeNAS 11.3-4U without problem. Picking the appropriated drive on the WEBUI import disk page automatically highlighted the "ext2" option:

in the shell:

The drive can also be mounted using the CLI:

Code:

root@freenas[/]# mount -vv -t ext2fs /dev/da3p1 /media
/dev/da3p1 on /media (ext2fs, local, fsid 67000000f3000000)
root@freenas[/]# ls -l /media
total 680888
-rw-r--r--  1 root  wheel  696539136 Aug 23 22:00 pfSense-CE-2.4.4-RELEASE-p3-amd64.iso
root@freenas[/]# umount /media

OK, it's not a USB drive and this was all done in virtual machines. But this import function looks to work to me.
