FreeNAS-9.2.1.6 --> NAS4Free

[Kris.Jacobs]

This afternoon I had some time to kill and my thoughts wandered to my NAS box. I've never been very happy with FreeNAS since iXSystems' changes...
I read the history of NAS4Free and immediately felt compelled to switch away from FreeNAS. I'm so glad I found this project, thank you!

I'm currently running FreeNAS 9.2.1.6.
It wasn't easy to determine zfs version in the way I thought, with "zpool get all pool1"

Code: Select all

[root@nas2014] ~# zpool get all pool1

[root@nas2014] ~# 

So I looked at dmesg and I found it:

Code: Select all

[root@nas2014] ~# dmesg | grep ZFS
ZFS filesystem version: 5
ZFS storage pool version: features support (5000)
[root@nas2014] ~# dmesg | grep zfs
[root@nas2014] ~# 

Based upon my research, it looks like I can migrate easily:
1. Create a new USB thumb drive with the NAS4Free image.
2. Boot it, configure it.
4. Import my zfs pool as-is
5. Enjoy!

Sound about right? Any caveats that I should be aware of?

Thank you!

EDIT: I meet all hardware requirements for NAS4Free x64 9.2.0.1.972

Sory to say so but, the feature flags freenas 9.2 uses are not compatible with the feature flags that nas4free supports.
