Adding an USB storage device to my USR8200 Router ended up with two errors.
- mount error
- disk full
Problem 1 mount error
The system log showed the following error even after formating the device using USR8200.
daemon.warn Failed to mount device kern.warn EXT2-fs warning (device sd(8,1)): ext2_read_super: mounting ext3 filesystem as ext2
After trying to preformat the disk or memory stick using XP, Windows 2008 R2 or cleaning the disk with diskpart I finaly got the idea to preformat an USB stick using my QNAP NAS . And it worked.
So here what you have to do:
- Create a partition of the size you need using your PC
- attach the disk to your QNAP NAS if you have one.
- reformat the partition using ext3
- detach your disk and connect it to USR8200 (it shows up as linux)
- Reformat the disk using ext2 on your USR8200
Problem 2 Disk full
The system log showed the following error while I tried to upload a few test files.
After looking closer at my FTP command line I recogniced the test folder I created was placed at the system root not within the new added disk subfolder. So i saved all files into the USR8200 it self and there is not a lot of space left.
So the problem is that like other “sealed” linux devices like some QNAP systems, USR8200 places your start position after a login by FTP straight at the root the device. This means, it i not usable for access by other people the your self.
