fsck


I'm no Linux expert but use it and get by. I now have a need to use fsck or e2fsck and I get:

# fsck
bash: fsck: command not found

What am I doing wrong.?

I'm having a problem with one of my servers and get:
'EXT3-fs: error loading journal'

and was told to use fsck or e2fsck to fix the problem. I have the drive on another server I have and it's not mounted and should be /dev/HDC

Thanks...

fsck worked on my /dev/hdc1 partition but on my /dev/hdc2 using fsck or e2fsck I get:

# /sbin/fsck /dev/hdc2
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: No such file or directory while trying to open /dev/hdc2

The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>


The /dev/hda drive from one server is having problems so I put it on my "sister" server and it's now /dev/hdc. This is how the drives were configured (df from sister server):
# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 113344072 13125148 94368456 13% /
/dev/hdb1 113544680 2401996 105281772 3% /home
/dev/hda1 101086 34408 61459 36% /boot
tmpfs 905696 0 905696 0% /dev/shm
none 905604 104 905500 1% /var/lib/xenstored

"fdisk -l" - may need root/sudo (also in /sbin).

/dev/hdc should be partitioned the same and basicly be the same as /dev/hda. Could it be someone hacked in to the server and repartition the disk.?


# /sbin/fdisk -l

That's a pretty big leap - fsck worked, so the filesystem appears valid. Try mounting it, and do "df -hT" to see how big it is.

Use [code] tags to get the output formatted so it can be read.

The problem is the partitions for /dev/hdc should be the same as /dev/hda. The /dev/hdc is the drive from the crashed "sister" server. They we both built at the same time and should be the same. Seems the /dev/hdc is missing 2 partitions.

OK... My bad...

I'm no expert on Linux but I made a stupid hardware mistake. I put the wrong drive on /dev/hdc, They're all 120GB drives and if I try to put the bad drive on it shows 80026GB. I will try to swap drive controller boards tomorrow and see if that helps, if not I think the drive is toast...

Happens to all of us.

Doesn't look good for that drive.
