[casper] Roach1 Host name lookup error.

2015-05-20 Thread Brad Dober
Hi Casperites,

I have a Roach1 which is booting from an SD card.
I booted it up yesterday, and it was displaying the STALE NFS handle
error that other people have seen in the past (which suggested a corrupt
flash card). I ran fsck and fixed several errors, and when rebooting, the
stale nfs handle error went away. However, now the ROACH could not connect
to the network.

When I run ifconfig 128.91.46.20 netmask 255.255.248.0 gateway 128.91.4,
I get:

gateway: Host name lookup failure


root@(none):~# hostname -v

(none)

and

root@(none):~# hostname --fqdn

hostname: Host name lookup failure


Any ideas on what could be causing this?

I ran into this a lot when trying to use the sdcard filesystem. I think the
problem is that the filesystem is ext2 or something old like that which is
prone to corruption if the system is hard rebooted. My advice is use NFS
file system.
