Btrfs scare

 May 31, 2026

Last weekend, I updated and rebooted the system, but it did not come back online. Checking with IPMI revealed that the ata-2 disk was not responding to the operating system, preventing a clean mount of the Btrfs filesystem and halting the system from completing the boot sequence.

My Btrfs array is composed of 6 SSD disks, all with different ages, except for the first two, which arrived together at the beginning. So, I was not overly concerned with one of the original disks failing. Sooner or later, it would have happened, and I was ready for it. Also, I set all data, metadata, and system to be RAID 1, so no data was at risk.
