Adding two more 12TB drives to the mirror
As mentioned in several previous posts, I’m moving a server from one chassis to another. None of the hardware is coming over. Just the jails and data. These drives came from serverpartdeals.com. They are used and re-certified. Recently, I’ve been trying out two new 12TB drives. I’m looking forward to the reduced noise level, as well as the reduced power consumption and heat.

How much noise will I lose when I power off this server?
This morning I pondered how much will noise reduce when I power off that server? From the comfort of my living room, directly above the rack in the basement, I powered it off. At first, I was disappointed. I could still hear that repetitive whine. After considering powering off one of the other hosts, I realized the noise I heard was the ceiling fan. After switching that off, I could no longer hear

They’re here! 2x (new-to-me 12TB HDD)
Yesterday, the drive cages arrived. Today, the 2x (new-to-me 12TB HDD) arrived. They are already mounted in their drive cages and installed. Let’s look at them. This post is similar to Testing two 12TB drives to a Dell R730 on FreeBSD. If you want to know most about the tests, see that. These drives came from serverpartdeals.com. They are used and re-certified. In this post: FreeBSD 13.2-RELEASE-p2 Dell R730 In they go This

Identifying jails and data to migrate from old host to new host
I’m retiring knew and moving the services over to r730-03. I recently added 2 12TB drives to the latter host. In this post, I’ll start the migration process by identifying what data needs to move, from where, and to where.

Testing two 12TB drives in a Dell R730 on FreeBSD
I’m ready to downsize. I’m going to replace knew with r730-03. The former has 20 5TB drives. I don’t need all that space now. I’ll settle for 12TB instead. The two new drives arrived today: [23:39 r730-03 dvl ~] % grep da2 /var/run/dmesg.boot da2 at mrsas0 bus 1 scbus1 target 2 lun 0 da2: Fixed Direct Access SPC-4 SCSI device da2: Serial Number 8CJVT8YE da2: 150.000MB/s transfers da2: 11444224MB (23437770752 512 byte sectors)

Monitor your backups
It’s good to do automated backups. When you do that, add monitoring to make sure the backups are occurring successfully. In my case, I backup using Bacula. Each job creates a new .bsr file. I copy these files to another location each day. Then I monitor the dates on those files and they should all be less then a day or so old. Edit (added 2023-08-29) This post is about upgrading net-mgmt/unifi6 to

What runs on the servers at home?
The last time I did this inventory was 2018. It is time for a refresh. I have added comments to the output of the jls command. This is a brief description of what runs in each jail. Retired hosts slocum and r720-01 have been powered off after being merged into r730-01. r730-01 r730-01 is a Dell R730 and is now my main server. [dan@slocum:~] $ jls -v | grep ACTIVE | cut -f

Dan makes another zpool

Maybe I need another zpool
I might need to create another zpool. Or perhaps move a drives/zpool from one host to another. In this post: FreeBSD 13.1 Background I am combining two hosts (slocum and r720-01) into one new host (r730-01). I have been moving jails from those hosts. I have an ansible playbook for creating new entries in /etc/jail.conf.d/. I thought I had the space calculations done right. Now I think I’m wrong.I’m already at 73% on
