Filesystem check

you can refer to this ubuntu thread for context, but i'll sum up what i'm trying to do here to spare the reading. basically i want to be able to schedule a filesystem check with automatic repairs at the next boot time. i know i can run:

but i'm not sure if this will try to automatically fix errors which is what i want to do. the reason i want to do this is because i experienced a power outage (the machine was not plugged into an UPS) and i want to make sure everything is ok.

what should i do?

It will do, if this is possible.

In the above post, your syntax is wrong. It should be (as root)
touch /forcefsck
shutdown -rF now used to be the command to Force a fsck at the next boot, but for some reason the -F flag has been removed from shutdown's options.

You could change the value for the number of times between checks with tune2fs's -c <count> option, or use the -t option for a time based value. You could use -d1 for daily checks. I'm not certain whether -c1 will run fsck every time or every other time.

The manpages suggests staggering the mount counts to avoid each filesystem being mounted at once which presumes a larger -c<count> value.
