Well shortly after posting about how I got my router loaded with DD-WRT and had all my USB drives working I discovered that my USB drives were no longer working.

After poking around a bit I found there were errors generated when the automount script was executing. In particular I was seeing:

root@BLT_ROUTER:/opt/etc# service automount status
cannot touch `/opt/etc/nomount': Input/output error
S35automount: Create /opt/etc/automount
cannot touch `/opt/etc/automount': Input/output error
I can not write /opt/etc/automount, abort

When I went to the directory I saw the following (most files removed to keep the list short)

root@BLT_ROUTER:/tmp# ls -al /opt/etc
total 1608
drwxr-xr-x 16 root root    4096 Dec 12 18:20 .

A quick search found this forum post where it was suggested to Stop automount (service automount stop) and then delete the two files.

This worked to delete the files, but when I rebooted the router only the /opt share came up. I messed around with this for quite a while and realized that something wasn’t right with the USB drives. So I disconnected them from the router and rebooted the router. Next I unplugged the USB drives power cord (where I noticed that one of the drives was unplugged, probably from when I was adding setting up my media server). After a short while I plugged in the drives power cord and the USB cable back into the router.

After another reboot the automount script came up correctly, however it lost my custom mounting assignments. So I edited the /opt/etc/automount file in the same manner that I posted earlier. Next I did restarted the automount and samba services

service automount stop
service automount start
service samba stop
service samba start

Finally, I’m backup and running.
