recover data from linear raid
Hello,
I had a scientific linux 3.0.4 system (rhel compatible), with 3
ide disks, one for / and two others in linear raid (250 gb and 300 gb
each).
This system was obsoleted so i move the raid disks to a new
scientific linux 3.0.7 installation. However, the raid array was not
detected ( I put the disks on the same channels and same master/lsave
setup as in the previous setup). In fact

Can't mount /home anymore
Hi!
I'm new to the list. I have a problem with mounting my home directory since
my PC crashed. I hope that I can get some help on this list as I don't know
much of ext3 myself.
The mount command for my /home gives me the following output:
# mount /dev/sda6 /mnt/tmp/
mount: wrong fs type, bad option, bad superblock on /dev/sda6,
missing codepage or other error

Hello,
I am member of research team on our Faculty of Information Technology

How are alternate superblocks repaired?
Hi,
Using dumpe2fs I have been able to determine that all of my alternate ext3 superblocks are corrupted (not clean), and only the primary superblock is valid, i.e. mount works and the ordered journal is applied. When the primary superblock gets flakey, i.e. the ext_attr Filesystem feature goes missing - not sure why this occurs. At this point, the mount does not apply the journal using the

ext3 + fs > 2Tbyte
Hi list
this is actually a problem on a debian system but I thought you might
be interested to hear of it and perhaps can offer some help.
I have a woody box (dell pe750, dual cpu) running a kernel from
backports.org (debian 'testing' packages built on a 'stable' box).
The kernel version is 2.6.7-1.backports.org.1.
This host is hooked up to an Apple Xserve RAID with a 2.3Tbyte

deleting partition does not effect superblock?
Hi,
I am using kernel 2.6.15.4.
On my system, I first created a partition with EXT3 and put some data
on it. Later, I deleted the partition, and re-created another
partition with the same starting block number and a higher ending
block number. I intended to format it with another filesystem, but
surprisingly (or maybe just to me), the superblock of the partition
had not changed. I could still

is a MachineBasicBlock a kind of superblock?
MachineBasicBlock allows for multiple terminators. Unconditional branches
and returns are marked as terminators; the MIPS backend also marks
conditional branches as terminators. The MachineBasicBlock then has a
helper function getFirstTerminator which iterates from the first terminator
to the end of the MBB.
So it seems to me that an MBB is a kind of superblock, single entrance and
multiple side

Ext3 Journal corruption on hitachi deskstars
I recently came across an enormous cluster of x86 clone machines running
fedora core 1 (2.4.24) which have typically all intel or amd have VIA IDE
chipsets.
They frequently experience corrupted journals rendering the ext3 partition
in read-only mode. More important than recovering the filesystem, I am
interested in finding the root of the problem.

Help needed to recover data from ext3 file system where mkfs was issued accidentally
Hi,
I connected my harddisk which had ext3 filesystem and some files
archived in it as slave device and issued "mkfs /dev/hdb2" accidentally.
Immediately I issued Ctrl C and stopped the process. But before that it
had deleted some 100 Blocks.
After that I am unable to boot that hard disk as primary device. The
system is asking me "please insert a valid boot device and press

Problem after upgrade to 1.4.7-1 (Bad magic number in superblock while opening context for device)
Hello Guys,
After upgrade to 1.4.7-1 my FS does not mount anymore. Just after
upgrade rpm, FS mount and works fine, but after reboot server, it does
not work anymore.
FS are created with ocfs2-1.4.4 and ocfs2-tools-1.4.3-1. If I downgrade
to old version doesn't work too.

More external journal woes.
I have been playing with external journals some more and thought I
should share some experiences.
I am running 2.4.16 with the ext3 patches from Andrew Morton
and e2fsprogs 1.25
I have an ext3fs filesystem on an 8 drive RAID5 array and place the
journal on a partition of the mirrored pair that I boot off (all
drives SCSI).
I have tried pulling the power cable and seeing what happens. I

another seriously corrupt ext3 -- pesky journal
Hi Ted and all,
I have a couple of questions near the end of this message, but first I have
to describe my problem in some detail.
The power failure on Thursday did something evil to my ext3 file system (box
running RH9+patches, ext3, /dev/md0, raid5 driver, 400GB f/s using 3x200GB
IDE drives and one hot-spare). The f/s got corrupt badly and the symptoms
are very similar to what Eddy described

Calculating volume size from superblock
Another simple question.
How do I calculate the size of the volume from the superblock?
Do I just use the two fields:
u_int32_t s_blocksize_bits; /* Blocksize for this fs */
u_int32_t s_clustersize_bits; /* Clustersize for this fs */
What is the formula to use?
Thanks,
John
