I did not make a backup of my fstab file and now I'm screwed. I deleted 2 lines and panicked and I don't know what they were. Here is what I have now:

# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/ / ext3 defaults,usrquota 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /proc proc defaults 0 0
none /sys sysfs defaults 0 0
LABEL=/tmp /tmp ext3 defaults 1 2


Any help whoud be GREAT!!!!

Hello Scott,

Can you provide a return for the following command?

Code:
mount
It might be swap you removed and possibly another partition, but that's impossible to know really. For my own curiosity, why did you elect to remove lines and then save the file? I just wondered why it was being edited in the first place basically.

Thanks!

I was trying to Secure /tmp and /dev/shm via 'vi /etc/fstab' and I did not know what I was doing and I panicked. I hit "x' to quit and again, I did not know what I was doing and hoping to get out of vi, and it saved my screw-up. My intention was just to look at fstab and not to edit it.

Hi Scott,

You haven't rebooted the machine since changing the /etc/fstab file, right? Just checking that's the case.

Also, have you tried asking your webhost what they normally use? I'm still not sure what might be removed beyond SWAP possibly (since I don't see anything in your existing /etc/fstab about SWAP). It's nearly impossible to know what it should have. Your hosting provider, NOC or datacenter should know what their images use for the /etc/fstab file.

Also for future reference, you can secure /tmp using the cPanel script:

/scripts/securetmp

And yes, I have rebooted a few times since then. When I screw up, I put 100% into it!

Once it's rebooted, even mount will change for the revised fstab, so that's too bad :(

All of the websites work just fine, I keep getting a 550 error when sending email to the server and sending email out of the server. When I send an email to someone within the server, it sends & receives just fine...

That doesn't seem likely to be related to fstab really. It shouldn't impact sending and receiving emails provided the disk space is sufficient in the existing partitions. You could always open up a ticket with us to check the email issues (WHM > Support Center > Contact cPanel), but I still think getting ahold of your host here is the necessary step for what they use by default for fstab. It would take them only a few moments to check their default settings for new servers they setup.

I started a ticket 7 hours ago. I am just getting a little antsy. I have also request from the datacenter for a copy of fstab. We will see how that goes.
