Nasty bug with invalid serial number

[tictactux]

(9.1.0.1 - Sandstorm (revision 358))

I have a no-name USB enclosure with an old 160GB disk in it. When I tried to attach it via Disks/Management, I would get an "XML Error - invalid character in line xyz" and then the Webgui is dead.
Remedy was to remount /cf as read/write (unmount /cf ; mount -o rw /dev/ada0s1a /cf) and edit the config.xml with vi. vi would display the (invalid) character as "<serial>^_</serial>", while the character would appear as Ctrl-Underscore (ASCII 31, Unit Separator control character). Changing that offending sequence to "<serial/>" would let me successfully reboot and re-use the NAS.

I am sure this is a bug in the USB/ATA enclosure, nonetheless the system should be able to sort such things out.

Suggestion: strip unprintable characters from serial numbers before applying it to the config file.

I think it is a bug, therefore I filed it there, too.

Thank you for reporting.
I didn't think broken S/N case.

I can confirm that the bug is fixed (or has been worked around sufficiently) in 9.1.0.1.394. Serial number now shows (correctly) as "n/a".
