I am hoping someone could help me understand what's going on. I have two HGST HUS726060ALN610 6TB 4kn drives and I'm trying to create a btrfs raid1 (in Ubuntu 22.04).
fdisk -l:
First I've noticed that mkfs.btrfs -d raid1 -m raid1 did not complete in over an hour, I didn't check for dmesg errors at the time but saw console output that the journalctl could not restart. I ended up doing a hard reset and wiped the drives. This time around I decided to create partitions on the drives first using cfdisk. It was while writing partition to one of the harddrives that started checking dmesg. This is the error I received:
I've not worked with 4kn drives before but I was under the impression that they are fully supported since kernel 2.6.x? The other thing is that the drives are in a USB enclosure (SYBA SY-ENC50104) using the JMicron JMS567 chipset. I wasn't able to find any mentions of compatibility issues and the drives seem to work fine on Windows in the same enclosure.
fdisk -l:
