Hello,
Have you tried to reinitialize the ata channel before changing the
partitions?
Try unmounting '/dev' and mounting it again (forcing it with '-f').
If the problem persist, the only alternative is to reboot. Do you have a
dynamic IP? If that is the case it is possible to add a crontab entry
that executes a script on each system startup. The script can send you
an e-mail to you using the internal sendmail (must be enabled for that)
relay so it will contain the IP of your server (in the complete
headers). Alternatively the script can upload a file containing the
output of 'ifconfig' to an FTP site.
If you are interested you can ask me for more information.
Best Regards,
Ale
