DEC850 : UFS or ZFS

[LeBleu]

Hi,
I need to reinstall my DEC850 and I wonder which file system is recommended?
It came with UFS, then ZFS support was added to opnsense.
Generic documentation is talking about ZFS, but what about  DEC850 specifically?
I mean, ZFS performance is very bad with nvme. DEC850 have a SSD so maybe performance will not be good.
Do you have some advice or performance benchmark for UFS ou ZFS on DEC850 ?

I mean, ZFS performance is very bad with nvme. DEC850 have a SSD so maybe performance will not be good.

What on earth gave you that idea? Do you know how many enterprise storage or virtualisation systems exist that run ZFS exclusively? And most of it on SSDs. I have a data center with roundabout one hundred servers, all SSD, all ZFS. Some SATA, some NVMe. No performance issues whatsoever.

Use ZFS. It's 2023.

Yep, ZFS. Since a year or so the factory hardware comes shipped with ZFS on root as well.

I have a DEC850 (64GB ram and 256GB ssd) with a Business license, updated to the latest version opnsense-business 24.10_7 and a Zenarmor license v1.18.3 with Elasticsearch DB.
Having purchased the hardware in 2022, the file system is UFS, but I would like to switch to ZFS.
Is there a way to switch to the new file system without reinstalling everything? If so, what is the procedure?
If not, how do I reinstall my DEC850 so that it boots with ZFS and then restore all the configurations, packages and licenses currently installed?

Thank you in advance

- export configuration
- connect serial/USB console
- boot from USB install medium
- install with ZFS
- reimport saved configuration

Reinstallation is the only way to change the file system type.

Regarding Zenarmor, will I need to export and then import its backup or will the OPNsense configuration file restore everything exactly as it was?
