In some testing that was being done the tester ran into the following: --
/mnt/abo is a filesystem in Raid1-configuration having two disks: /dev/sdg2 and /dev/sdg3. When trying to remove one of the devices, you get this error on the console: # btrfs device delete /dev/sdg2 /mnt/abo ERROR: error removing the device '/dev/sdg2' - Invalid argument /var/log/messages shows the real error: Jan 29 13:54:58 ca-ostest202 kernel: btrfs: unable to go below two devices on raid1 The error message on the console output is wrong : '/dev/sdg2' is not an invalid argument, there's another reason why the delete-action can't be executed. -- Looking at it I can see the EINVAL being correct because it is being told to remove a member from a raid1 with only 2 members, but I can see how that message could be confusing as well. Is there some place that tells users to look at /var/log/messages to see the other message? Wondering if the error message should point users to /var/log/messages to get more details. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
