Hi, I want to know if re-mounting the root filesystem read-only should change subvolumes mounted as read-write to read-only as well? We do allow mounting subvolumes RW _after_ the root filesystem is mounted RO. # mount /dev/vdb /mnt # mount -o ro,subvol=svro /dev/vdb /mnt/svro # mount -o rw,subvol=svrw /dev/vdb /mnt/svrw # mount -o remount,ro /dev/vdb /mnt # touch /mnt/f3 touch: cannot touch '/mnt/f3': Read-only file system Changes subvolume to read-only as well. # touch /mnt/svrw/f3 touch: cannot touch '/mnt/svrw/f3': Read-only file system However, remount of subvol as RW after remount,ro of root works: # mount -o remount,rw,subvol=svrw /dev/vdb /mnt/svrw # touch /mnt/svrw/f3 -- Goldwyn -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
