UNIX for Dummies Questions & Answers

Does anyone know of any commands that offer the same sort of facilities of scandisk on windows. My Linux server (Mandrake 6.2) keeps crashing and gives hard disk errors when I reboot. I've used fcsk to fix any problems that arise but when I use dumpe2fs to display disk information it says that the file system is still not clean. Any ideas how to make it clean and check for erros (i.e. bad blocks etc)

Thanks for your help

Here is what the manual says:

Will keep you bust for a while...


fsck - check and repair file systems

OPTIONS
-FFSType Specify the file system type on which to operate.

-m Check but do not repair. This option checks that
the file system is suitable for mounting, return-
ing the appropriate exit status. If the file sys-
tem is ready for mounting, fsck displays a mes-
sage such as:

ufs fsck: sanity check: /dev/rdsk/c0t3d0s1 okay

f Force checking of file systems regard-
less of the state of their super block
clean flag.

p Check and fix the file system non-
interactively ("preen"). Exit immedi-
ately if there is a problem requiring
intervention. This option is required to
enable parallel file system checking.

w Check writable file systems only.

EXIT STATUS
0 file system is okay and does not need checking

1 erroneous parameters are specified

32 file system is unmounted and needs checking (fsck
-m only)

33 file system is already mounted

34 cannot stat device

36 uncorrectable errors detected - terminate normally

37 a signal was caught during processing

39 uncorrectable errors detected - terminate immedi-
ately
