I just now rebooted my debian server for maintainance reasons (changed the kernel). However, it seemed to not complete the reboot. So I logged in using Remote KVM and found it hanging at a forced disk check. I (now) know how to avoid the forced disk check:
sudo tune2fs -c 0 -i 0 /dev/sdaX
However, I wonder what's good practice for actual Webservers regarding disk checks. Do you guys simply never run disk checks on your server systems? Do you occasionally take the hour or so of downtime to have it run a disk check or is there even a way to have it run during regular uptime?
