fsck?

[jmadero]

How do I run a manual fsck? When I try after boot it tells me that running it after filesystem is mounted is very dangerous....for some reason my Ubuntu isn't running fsck even after I do a force shutdown (had to a couple times in the past couple days and typically it would run the fsck on boot but now it just starts up still). Thanks all

Boot up from LiveCD and run fsck on any partition.
By default, Linux runs fsck on every 36th boot up.

By default, Linux runs fsck on every 36th boot up.

Only if you are using ext2/ext3 and even when using those filesystems not all distros do this by defualt because the process can take a long time especially on large disks causing a lot of down time.

jmadero, I recommend you use small live discs such as partedmagic or gparted.

I have checked in SuSe, Fedora, Ubuntu, Sabayon and Debian. All of these run fsck on every 36th boot. One can turn it off by setting it value to zero in /etc/fstab file.
