Nope, that filesystem is still mounted and in use, but still a very good deduction... Trying smartmonctl just now on that drive (/dev/sdf) gives errors suggesting that the drive is no longer responding at all :-( There is also a steady repeat of: kernel: sd 7:0:0:0: [sdf] CDB: kernel: cdb[0]=0x2a: 2a 00 04 02 45 80 00 00 08 00 kernel: sd 7:0:0:0: [sdf] Unhandled error code kernel: sd 7:0:0:0: [sdf] kernel: Result: hostbyte=0x04 driverbyte=0x00 (Must watch that lot doesn't fill the log.) Should I try a: btrfs device delete missing /mnt/data2 or do I need to unmount or remount first? ... And the system is live and not to be rebooted if at all possible until the weekend...
