I can assure you that drive (it is HDD) is perfectly functional with 0 SMART
errors or warnings and doesn't have any problems. dmesg is clean in that regard
too, HDD itself can be excluded from potential causes.
There were however some memory-related issues on my machine a few months ago,
so

Support for a new command is being added here:
btrfs dev ignore
Which shall undo the effects of the command
btrfs dev scan
This cli/ioctl is needed as there is no way to continue to mount in
degraded mode if the device is already scanned, which is required to
recover from the split brain raid
We need device delete from the dev_list so create a new function,
instead of refactor of btrfs_free_stale_device() because,
btrfs_free_stale_device() doesn't hold device_list_mutex which
is actually needed here.

fstrim should trim free space, but it only trims unallocated. This is
with kernel 4.14.0 and the entire 4.13 series. I'm pretty sure it
behaved this way with 4.12 also.
[root@f27h ~]# fstrim -v /
/: 39 GiB (41841328128 bytes) trimmed

Well, I was told it should also trim free space ...
