- Comment on how often do your 3rdparty "refurb" drives last? 6 days ago:
I have some that were bought in May of 2021. They are HGST Ultrastar 7K4000 4TB 64MB Cache 7200RPM
I bought 12, ran a full burn in with bad blocks, long and short tests ran then for 3 months with data then cleared the old pool. They are in a RaidZ3 and are still working fine.
- Comment on syncthing but with file sharing 1 week ago:
Make a syncthing directory for each person you want to share with. For only a few people it’s really simple. I do this with a few different things. Each “share” can be setup with individuals or groups as you need.

ZFS rollbacks only has to roll back the changed files so it’s a pretty quick process unless there were some major changes.
Yeah, that was the goal with the D3’s. I’m trying to get things to the point where if I’m no longer able to handle things that the router will stay updated and be simple to repair for my family.

I keep config backups of the config as well but my boot drive is a pair of mirrored Intel D3-S4510’s that are underprovioned by 50GB.
Rollback time will technically depend on the size of the change since a rollback only replaces changed files so that will depend on how far back you are rolling back to. My largest snapshot references about 2GB and is a little over 4 months old, I would estimate about 5 minutes at most rolling back to that point.

I’ve never been comfortable virtualizing a router. Nearly anything else is not an issue.
- Comment on For people using OpnSense who want some automatic snapshots. 2 weeks ago:
On OpnSense no. I previously did not have snapshots created. I have on FreeNAS when I had a setting issue that came up. Fundamentally it should be no different.
I have had to reinstall OpnSense before and would rather not go through that again if at all possible.

- Comment on Self-Hosting a DNS Sinkhole is really important 3 weeks ago:
A snapshot is an image of the complete system at the time of creation that tracks changes and can be restored if needed.
- Comment on Self-Hosting a DNS Sinkhole is really important 3 weeks ago:
No problem.
Be sure to set a cron job for updating the DNS Blocklists, running zcrubs, smart tests, and trim if you are using a ssd.
I am working on a way to do snapshots for the system as well for super simple restores that are automatically created. Before an update you WILL want to have a snapshot available. Once snapshots are automated I will probably start doing automatic updates. It basically creates a system similar to how an immutable OS works, if something goofs you can simply roll back to a previous working state and pause updates. I previously had a script I setup via a cron job but the system removed the job during an update.

Try setting a tunable of:
net.link.ether.inet.max_age = 540
By default FreeBSD sets a 20 minute ARP maximum age while many ONT’s set a 9 minute maximum age. This will show up as performance issues initially then cause other issues.
Also Realtek NIC’s are notorious for issues with FreeBSD, so if you are using one replacing it with an Intel one is highly recommended.

Absolutely. Remember to enable a cron job in the OpnSense - System > Settings > cron to update the Blocklists. Otherwise you are likely out of date.
