Unhappy Boot Problem with Filesystem Error on second Harddisk


Hi everybody,

I ve been running a little home server with Mandrake 10.0 for a while now and this worked fine.

the Server is a simple 500Mhz P3 128 MB Ram 2 Harddisks (5GB + 1,2GB)

This morning I tried to boot but while boot the system halted saying:

Quote:
Attempt to read block from filesystem resulted
in short read while trying to open /dev/hdb1

Could this be a zero-length partition?
Well, its not a zero-length partition...,

The system won't boot any further and only give a shell (Where I cant start any of ther server procesess like mysql httpd etc)

I can mount /dev/hdb5 manually and fsck won't print any errors...

I can't mount /dev/hdb1 and fsck will only repeat the error message above


If you have any !! ideas how i can fix the problem or at least backup my mysql-data (possibly over my network (which so far hasnt started) ) I ' d be appreciating it....


A very troubled chansel

What sort of filesystem is (was?) the troubled partition running with?

Just assuming ext2, there are some extended options to run with it: "-c" runs a read check on the blocks, "-c" again does a read/write test, "-f" forces a scan even if it otherwise thinks it is clean. If you get it fixed, I'll definitely recommend using a journalled filesystem of some kind. I personally have had no trouble with ext3, and I'm sure it's saved my bacon a time or two.

The filesystem is / was ext3.

I ran the checks with forced option (-f) but nothing - cant read

It seems the Partitiontable seems to be damaged severely, although I found a tool which is said to repair these kinds of problems

http://www.cgsecurity.org/testdisk_doc/testdisk.html

With that I could "recover " the 2 lost partitions (and egt a list of valid filenames of them while running the programme) but as soon as I save the recocvered partition table and reboot the system , the changes are lost again...

For now I just disabled the partitions in /etc/fstab and the machine boots again.

The hard disk is fairly old (8 years or so) and I'll probably just get a new one

But thanks for your comment
