bcachefs version
bcachefs tool version v0.1-366-g3785043
As explained in #320 I have a bcachefs filesystem with multiple devices in which one of the devices has failed. I've attempted to remove it with bcachefs device remove and previously encountered a kernel bug which has been fixed as of c85e27c.
However now when I attempt to remove the device, I am encountering other errors (including at one point a kernel bug when I tried to unmount the filesystem after the device failed to be removed from a previous command).
In particular, I did the following:
bcachefs unlock <device path>
mount -t bcachefs -o rw,very_degraded <devices> <mount point>
This seems to work as expected:
bcachefs device remove -f 2 <mount point> (device 2 is the one that is missing, according to bcachefs fs usage)
This results in the following errors in the kernel log:
bcachefs device remove -f /dev/sda1 (This is another device which is not failed, but which I wanted to remove so that I could use it to transfer data from the bcachefs filesystem. I think the error is simply because there is still some btree data on it.)
