A few words on selecting which port to use:
particular configuration.
For new users, the following guidelines can help:
- - if you have only a single drive, use port 2.
+ - if you have only a single drive that will be formatted by the NSLU2,
+ use port 2.
- if you have a single drive that will be formatted by the NSLU2, and
all other drives or flash devices will be either FAT or NTFS, use
port 2.
- if you have two drives, and both will be formatted by the NSLU2, then
unsling to the drive in port 1.
- If you unsling to port 2, and later add a drive in port 1 that will be
- formatted by the NSLU2, initial testing indicates that it should work
- as expected -- however, the drive to be added MUST be formatted by the
- unslung NSLU2 in question, and once formatted, the drive must NOT be
- removed -- as the unslung NSLU2 will move it's "conf" datafiles to the
- drive in port 1 during the format, and thus will be dependent upon the
- presence of both drives for proper operation. You have been warned!

NSLU2. So the simple rule is that if the NSLU2 web interface "Disk"
page does not list the disk as "Formatted (ext3)", you will be unable

5) In the telnet session, run "/sbin/unsling disk2".
