To whom it may concern,
well I compiled and ran the XFS programs but I got the same error message:
attempting to find secondary superblock...
.................................................................................found
candidate secondary superblock...
superblock read failed, offset 12884901888, size 2048, ag 4294967295,
rval 3
fatal error -- Input/output error
I will leave the partition alone for a while; is there any way around
it? Is there any other way to extract data from the XFS?
Really need any help :(

P.S. How do I find out version of xfs_repair I have currently installed?
P.P.S. cfdisk gives me this error message
FATAL ERROR: Bad primary partition 1: logical partitions overlap
Press any key to exit cfdisk

The userspace programs are at:
ftp://oss.sgi.com/projects/xfs/download/cmd_tars
but xfsprogs (which contains xfs_repair) is at 2.0.6; I will put out a
newer version in an hour or so.
if you have trouble with newer xfsprogs, send it back to the list; I
will be out next week.

hello,
sorry that I did not explained the problem better, but I was in time
pressure; you were right, the boot manager has probably overwritten
superblock of that FS - possibly the whole program got installed there -
well, I'll never do stuff like this under pressure again :)))
So I tried XFS managing programs which I found in my system (I have
Slackware 8.1 kernel 2.4.19-pre10 and XFS patch for this version of
kernel);
when I started with XFS I donwloaded some standalone apps too, but
they are
stored on that XFS patrition :((
Here's the outcome of xfs_repair command:
bash-2.05a# xfs_repair /dev/hda3
Phase 1 - find and verify superblock...
bad primary superblock - bad magic number !!!
attempting to find secondary superblock...

.....found candidate secondary superblock...

-----------------
Well every other XFS related command said errors concernig that magic
number, for example xfs_db:
bash-2.05a# xfs_db /dev/hda3
xfs_db: unexpected XFS SB magic number 0xc4a11da3
xfs_db:
--------------------
Please, if this can be fixed, can you give URL to that utils; because
I'm
still quite new to Linux and I have not got familiar with directory
structures of it yet :))
Thanks a lot for any help;

Subject: Re: problem with XFS SB magic number
The original problem is almost certainly that your boot manager put
something on block zero of your xfs partition; this is where the xfs
superblock lives, so it was corrupted.
What version of xfsprogs do you have? I'll make sure the ftp site has
the latest version packaged up; you should get the latest if you don't
have it already.
If you send the output of your xfs_repair run, that might offer some
hints.

To whom it may concern,
well I have 2 disks on my machine - one for MS Windows - primary slave
and other for Linux - primary master (3 partitions; one ext2; 2nd swap
and third XFS for data) I have installed XOSL (boot manager) on
Windows
HDD and after that during booting pure linux XFS SB magic number error
occured; I have already uninstalled XOSL, but it did not helped at
all;
the should be no physical errors on disk, but when I tried xfs_repair;
it found secondary Super block but it was corrupted and the program
ended with an I/O error;
Please is there any way how to correct this?
