Updating my poudriere jail after updating the host to FreeBSD 15.0
This post is related to Upgrading a FreeBSD 14.3 host to FreeBSD 15.0 which I wrote and ran earlier this evening. I’m now back from my Indian dinner and watching the Superbowl (0:15 left in the 2nd half). I was updating r730-01 and got to the point of where I need to updated the packages on the host. I couldn’t do that. I hope my own FreeBSD pkg repo. What I did before

bash: line 1: /usr/local/sbin/rrsync: No such file or directory
Today I got this message in the logs: The rest of the message told me it was a cronjob run by the rsyncer user on my x8dtu host. Looking at that cronjob I found: [rsyncer@x8dtu ~]$ crontab -l # use /bin/sh to run commands, overriding the default set by cron SHELL=/bin/sh # mail any output to `dan’, no matter whose crontab this is MAILTO=dan@langille.org # take a local copy of the bacula stuff

Copying everything off a zpool, destroying it, creating a new one, and copying everything back
I have a problem with a zpool. To be clear, this really isn’t a problem. I’m not aware of any I/O throttling etc. It is just something I would like to change. [18:26 r720-02 dvl ~] % zpool status data01 pool: data01 state: ONLINE status: One or more devices are configured to use a non-native block size. Expect reduced performance. action: Replace affected devices with devices that support the configured block size, or
r730-01
This post has been replaced by a newer post. This is the Dell R730 host known as r730-01. For reference, the previous post on this server is still available. This host has undergone major storage changes over the past few weeks. This post will reflect those changes This is my primary developer server in my basement. gpart zpool list zpool status zfs list dmesg sesutil show [16:57 r730-01 dvl ~] % sudo sesutil
Making room to creating a raidz2 from 8x 4TB devices – here. we. go.
It’s time. Time to create the 8x 4T raidz2 zpool. That doesn’t happen in this post, hopefully the next one. But first, I have to move some stuff around, to free up all the 4TB devices. The host has 4 devices (NVMe) and I moved in two more, 4TB SSDs. From /var/log/messages: Dec 9 00:24:29 r730-01 kernel: mrsas0: System PD created target ID: 0xc Dec 9 00:24:29 r730-01 kernel: mrsas0: System PD created

PostgreSQL: MD5 password support is deprecated – updating the user passwords
Eight years ago, PostgreSQL introduced scram-sha-256 hashes for passwords. Eleven months ago, MD5 was deprecated. Yesterday, I got caught up with all this. Some of this post will deal with how I fixed it, but mostly it is documenting (for myself) what I did. The fix covers several services and takes place over multiple days. First, some background on why this change has come into focus for me. I have a FreeBSD jail

What will I do with those 2 x 1TB drives?
During zfs: setting compression and adding new vdevs I replace 2x 1TB drives with 2x 4TB drives. This afternoon as I was taking laundry down to the basement, I realized: I have two unused drives in the host. Either I remove them or I repurpose them. I know I have 4x 1TB drives (two SSDs and two NVMe). I could make a 2TB mirror out of them. Where can I use them? r730-03

zfs: setting compression and adding new vdevs
If you read my recent posts, I’m replacing an existing zpool with new devices. At first, I went to copy the old zpool to a new zpool. I then decided instead of copying, to replace. I’m also going to see about compression. I’m sure it won’t take effect, because replace is a block-by-block copy, or so I think. We’ll confirm. Before Here is the zpool, really, just the top-level filesystem. Notice how compression

Moving a zpool to new devices – after the syncoid copy – oh wait, zfs replace
This morning, as I was typing the subject of this blog post, I realized I don’t have to do this copying. The new devices are staying in this host. It is better for me to add the new devices to the zpool and remove the old devices. That is so much easier. The existing zpool can stay in use and there is no interruption in service. NOTE: after publishing this entry, I realized
