Hello,
I have noticed I have the following in my dmesg:
[319769.043163] nbd: registered device at major 43
[319769.104176] nbd11: unknown partition table
[319769.130273] device fsid c2598ff2-1e3e-4edf-ab19-1f7ab41b0160 devid 1 transid 125743 /dev/nbd11
[319769.130522] btrfs: force lzo compression
[319769.130528] btrfs: disk space caching is enabled
[319802.926547] Btrfs detected SSD devices, enabling SSD mode
The /dev/nbd11 device itself is not an SSD, it's an LVM volume situated on a
RAID5 array of regular hard drives, exported via NBD from another computer.

With respect,
