Hi Andrey,
I notice that you have an external Seagate SMR drive, I am encountering
some trouble and was wondering if you (or anyone in CC) could have some
feedback.
While the drives I have (PID 0xab45, "Backup+ Hub BK") are used
without problem with very light loads, I'm starting to get annoyed when
doing more serious work.
Here is a series of messages (v4.14) I have when simply trying to balance 1
chunk of BTRFS data, ie. write 5 GiB, and waiting a long time in-between:

Do you see such things?
I understand that latencies can climb to several seconds as the disks can do GC,
and suspect that the issues (sometimes the USB reset doesn't work and a reboot
is needed...) are due to some unawareness of that, but I don't know.
There are several threads on distribution forums & bug trackers, but nothing
really helpful, and I didn't see much on LKML.
Regards,
