As asked elsewhere, will I be soldering circuit boards?

No, just the wires, no boards or components.

I plan to replace some fans and some soldering will be required. I haven't done any soldering in decades.

Which iron would you recommend for this, given it won't be used much?

The fan connector is not standard, so I'll buy a compatible fan, cut, and solder in.

I've been given an R720 and plenty of RAM (different donations, same source). The plan: get drive cages and drives, configure it as a FreshPorts node, put it back into the data center. You may recall I brought home a broken server back in late August. FreshPorts has been running on the old server since then.

I hope to crowd-source the funds for that new hardware.

I'm also working on getting FreshPorts onto AWS as well.

Hardware starts arriving today.

Next: flash the H710 mini into IT mode.

I ran tests over the weekend to make sure the rack shuts down smoothly when a power failure occurs. Just as important, I wanted to make sure it starts up properly and unattended. Usually I am not near the rack when power is restored.

It takes about 3.5-4 minutes to shut down.

From power restoration, it is about 7 minutes before all hosts are up, about 15 minutes for all jails to be running, and 25 minutes before Nagios is all green.

Hmm, named on one host just crashed.

I've been using @Tarsnap since at least 2015-10-09

I recently decided to purge some old backups. Along the way, I found out just how much compression and deduplication are saving on storage space.

re github.com/dlangille/mkjail

Have you ever used this type of notation for specifying a run of IP addresses on a host?

ipv4_addrs_lo1="192.168.0.1-9/29"

Specifically, that 1-9 part

Great FreshPorts idea from
kaevans91:

"Add feature to watch for new package sets"

Pick an ABI (or several) such as FreeBSD:12:amd64 and receive an email when FreshPorts notices that this repo has been rebuilt.

FreshPorts checks hourly.

DNS stopped working on a jail, but only some DNS queries were failing. Changing an IP address to a /32 fixed it. Order of IP address within the jail is important. That /32 changed the order. Related to allow-recursion within named:

Got this after upgrading MySQL from 5.7.30 to 5.7.31

mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s)

Fixed it with permissions.
