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 ?

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.
Cheers,
Franco

Thanks franco
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?
