Warning for the next reboot / 2015-10-26

Interesting information in the message of the day:

*** /dev/sda1 will be checked for errors at next reboot ***
*** /dev/mapper/vgsw-camera will be checked for errors at next reboot ***
*** /dev/mapper/vgsw-scratch will be checked for errors at next reboot ***
*** /dev/sdc1 will be checked for errors at next reboot ***
*** /dev/sdc2 will be checked for errors at next reboot ***
*** /dev/sda6 will be checked for errors at next reboot ***

Which translates to 'your next system startup will take up to an hour' for me.

This explains why logging in sometimes takes a while: this check probably wakes the disks from sleep some of the time.

I'll go do some of those filesystem checks by hand: I don't want to be offline for up to an hour when I reboot.
