@MvL Hello again. I haven’t been following the progress on this one specifically, so I’ll just link again to the thread that seems to have the most info in this area:
Haven’t seen any progress reported for SMR drives in the linux-btrfs mailing list though. So probably down to the nature of the SMR management as before, ie host or disk based.
I have a couple of Seagate 8TB Archive drives. Not sure what management they have. I think I asked before but can’t recall which forum. If I remember correctly this was also in combination with RAID. Maybe it was ZFS…
