I lost my super block in SUSE Linux?

could be a case of http://en.wikipedia.org/wiki/RAID_5#RAID_5_disk_fa...

but replacing the drive with the defective block should allow raid to rebuild the missing information from the other three disks.

your question isn't clear:

is the corrupt block on /home or on / ?

if later, simply reinstall openSUSE and choose to mount /home during install (choose advanced disk configuration) without formating it.

if the corrupt block is on /home, unless you have a backup...

ADDITIONAL - reinstall

three things:

-1-

you can reinstall only / (root & all);

to do so, start the install, preferably the same version as already was installed

accept the license & a couple more things

when PARTITIONING comes, click custom and then Advanced (possibly also Expert only or so)

select the same disks / volumes for / (root & all) that you have now & click Edit

choose to FORMAT (only for / (root & all) /!\), pick / in mount as & OK

select disks / volume that are your /home now & click on Edit

do ##NOT## choose format (of course; it isn't by default) but simply mount as /home & OK

Accept & carry on with install

-2-

even though install is most likely to go well, chances are that the sector which went bad is physically damaged & will thus soon corrupt your / (root & all) AGAIN ====>>>> 1st thing burn whatever (important) data you have on /home to DVD (or copy it to an external / USB hard disk 'cuz

-3-

depending on how the / (root & all) is spread over the same disks then the /home it may or may not be possible to exchange easily the faulty disk, but, SOONER (or later) the bad sector will become allocated again; maybe to a silly readme or document you never going to need & you won't be bothered by it, but if the bad sector is used by a file belonging to the kernel or X.org, you won't be able to boot / mount / startx, again

===>>> once you have burnt all your data to DVD or copied it , replace the faulty disk; personally, i have had workstation / server motherboard with build in RAID controllers for years and always used them as NON-RAID; the only way to use RAID in a meaningful way is to have an external disk array with a dedicated (iSCSI) controller. anything else is nonsense. use your four HDs as FOUR HDs, putting / (including /home /opt aso.) on one, /usr on a 2nd & the 3rd one for your own data copy / home backup; and you might even keep the 4th HD for testing new releases or keeping an XP partition. RAID on a home system is meaningless.

and backup your (important) data to DVD/RW; they are so cheap, nowadays...

just my 2 cents...

PS: in case -1- doesn't work (bad sector gets written to during install & system still won't start 8-X :@ ):

download SystemRescueCD from http://sourceforge.net/project/showfiles.php?group...

i have been using version 0.4.3 for yrs; never bothered moving to 1.0 because 0.4.3 has everything i need, but you'll need 1.0 because only 1.0 has RAID support :-/

burn to CD (200 MB) & boot from it

once you are started

HH:MM > ls -l /dev/## name of your home vol.grp. / name of your home volume##

## if you see this okay (no error msg)

HH:MM > mkdir /mnt/my_home

HH:MM > mount /dev/## name of your home vol.grp. / name of your home volume## /mnt/my_home

# system rescue CD support burning to DVD, but you might want to buy an USB disk just for that

# to see the device of the USB HD

HH:MM > ls -l /dev/sd*

# it should be the last one, e.g. /dev/sde1

HH:MM > mkdir /mnt/usb

HH:MM > mount /dev/sde1 /mnt/usb

HH:MM > mc

# mc / midnight commander is a Norton Commander like file manager that will allow you to copy easily the content of your /home to the USB HD

(select /mnt/my_home on the left, /mnt/usb on the right, select everything on the left & press F5 to copy it to the right

et voilà
