data04: DEGRADED – oh and have I mentioned WatchGoose?

Leave a Comment / nvme, ZFS / By /

I saw this today in my logs on r730-01. It looks similar to a previous DEGRADED even back on July 2. In this case, the device is S7KGNU0Y915666E, not S7KGNU0Y912955D as it was back then. The zpool status is: [12:16 r730-01 dvl ~] % zpool status data04 pool: data04 state: DEGRADED status: One or more devices have been removed. Sufficient replicas exist for the pool to continue functioning in a degraded state. action:

data04: DEGRADED

Leave a Comment / nvme, ZFS / By /

This morning I noticed this in the logs after doing some pkg upgrade. I was mainly updating openvpn, but in that operation, fail2ban was removed (because I went from python312 to python314). I noticed it missing on one host: I ran this grep to verify fail2ban had been removed from another host: Well, this host doesn’t run fail2ban, but those messages are “interesting”. How much is nvme mentioned in the logs? [12:31 r730-01

This post will be short on detail. I’m writing it for myself, to document what I’m doing. I suspect Migrating data02/freshports/dev-ingress01 to another zpool will be more useful to you.

Cleaning up snapshots

Now that I’ve copied two filesets from one zpool to another, let’s delete old snapshots.

Migrating ZFS filesystems from one zpool to another – same host

Leave a Comment / FreeBSD, Open Source, ZFS / By /

Not so long ago, a disk space issue arose. I obtained some new drives (thank you to those who donated) and I consolidated some of the space. However, I had not yet taken care of the problem. For my first example, I’ll copy my vm data over. In my next post, I’ll copy dev.freshports.org to a new dataset. In this post: FreeBSD 15.0 What happened? Yesterday, the chickens came home to roost.

nagios03: drive recovery

Leave a Comment / Azure, FreeBSD, ZFS / By /

After zpool upgrade blocked by gpart: /dev/da0p1: not enough space, I’ve decided to create a new Azure VM, snapshot the now-faulty-drive, attach it to the host, and start zfs replication to copy the data to new drive. Or something like that. The existing drive needs to be imported with a checkpoint rollback, then copied to a drive with different partition sizes. Here’s the new host: My first impression: why only 174K for the
