Hi @LBarry,

Welcome to the forum; I wished it were under better circumstances, though. Iā€™m not an expert in the matter, but it seems to me like you are unfortunately facing hardware issues, especially when seeing the following error:

Now, these relate to your sdi device, while the other btrfs related errors relate to sdf, but from your lsblk output, it seems that only sdf is mounted. Should I understand that all these 4Tb drives are under a same pool? Would you be able to post a screenshot of your ā€œPoolsā€ page, as well as one for the pool details for the pool(s) in question?

In addition, some btrfs-specific info could show something helpful:

btrfs fi show

as well as:

btrfs dev stats /mnt2/Pool-0

Finally, would you able to tell us more about your disks setup as well as the version of Rocsktor you are using? In particular, the following linesā€¦

tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK

ā€¦ seem to indicate you might be using some USB passthrough ā€œdeviceā€ so are you using some sort of USB drive dock, or something similar? Are all your drives connected directly to the motherboard via SATA?
It could be a bad drive, or maybe some flaky connection/cable, or even flaky USB controller if you are using one, for instance; thatā€™s why I was curious about your setup.

In any case, I would make sure your backups are refreshed in the meantime while your pool is mounted read-only, in case you have indeed a failing piece of hardware somewhere.

Sorry for not giving a more clear answer, but hopefully itā€™ll bring more element of answer.
