That should not hurt much.

Generally, that means your network didn't come up.

oh,
Likely this is why the network didn't come up.

What filesystem are you using? ext2/ext3 are supposed to handle this 
pretty well and it's a very long time since I had a problem with them. 
OTOH some others (and I don't want to cast nasturtiums) have less 
stellar reputations.

In any event, booting your rescue CD and running a filesystem check is a 
good start. I'm a little torn about recommending a read-only check - it 
sounds conservative, but it won't fix the problem. OTOH, a rw test 
(necessary to fix it) also has the possibility to make it worse.

It's a quandary, best resulved by Roy.
