Runing fsck at boot time

Running fsck at boot time

Open a terminal window and change to root using (su -) that is SU Dash,
then type:

touch /forcefsck -p (-p to fix all no questions) Run again on Blue FIC
Debian.

and then reboot. This will force a file system check during the boot
process.

Go there and read the rest of the Posts to get Context (remember
improperly run fsck, such as on a mounted file system, can damage your
file system even more!)...

More fsck info...

su works the same as su - (still need root pass)
I wonder if e2fsck would be better for ext4 or lvm file system...
Could try on Blue FIC Debian System first to see how it works. Unplug
WinXP HD and Plug in the Debian HD...

Run e2fsck on Fedora 12 L and see if can fix

If works could run on Mom's Fedora 12 too...
I saw this command on a somewhat related post "yum clean all", they say
it can't hurt anything. Could try it to see if helps anything. Didn't
Help my problem with file permissions.

My Fedora 12 L drive would be... e2fsck /dev/sdb2
Tried running on Mom's running on SystemRescue CD, "e2fsck -p", but
couldn't install any new apps. Have to use another Distro that doesn't
auto mount drives.

Results of running just e2fsck in my Fedora 13

[don@fedora13-gatewaygt5408 ~]$ su
Password:
[root@fedora13-gatewaygt5408 don]# e2fsck
Usage: e2fsck [-panyrcdfvtDFV] [-b superblock] [-B blocksize]
[-I inode_buffer_blocks] [-P process_inode_size]
[-l|-L bad_blocks_file] [-C fd] [-j external_journal]
[-E extended-options] device

Emergency help:
-p Automatic repair (no questions)
-n Make no changes to the filesystem
-y Assume "yes" to all questions
-c Check for bad blocks and add them to the badblock
list
-f Force checking even if filesystem is marked clean
-v Be verbose
-b superblock Use alternative superblock
-B blocksize Force blocksize when looking for superblock
-j external_journal Set location of the external journal
-l bad_blocks_file Add to badblocks list

Ext2fs Home Page

Release 1.41.11 of e2fsprogs is available!

On May 17, 2010, version 1.41.12 of e2fsprogs was announced.
Ext2fs Utilities
The following Ext2fs Utilities are available:

* e2fsprogs, which consists of e2fsck, mke2fs, debugfs, dumpe2fs,
tune2fs, and most of the other core ext2fs filesystem utilities.
* dump, which will allow you to make backups of your ext2
filesystems. It uses a format which is compatible with the BSD dump and
restore programs.
* defrag, which will defragment your ext2 filesystem
* ext2ed, which is a text/windows (curses) interface for examining
and editing an ext2 filesystem. It unfortunately is limited to
filesystems smaller than 2GB, and is heavily Intel byte order dependent,
and has apparently been abandoned by its original author. (So for those
people who were used to seeing ext2ed in older Linux distributions, and
wondered where it went to, that's the explanation.)

It has been integrated into e2fsprogs version 1.28, but its
limitations mean that it should only be used by developers who need to
generate test cases.
* Ext2fsd, An ext2 filesystem driver for Windows NT/2K/XP. The most
recent version has read-write support.
