Hello, list,

Recently, one of our servers has been crashed because of some harddisk
problem. In several days before, the hd speed of this server become a little
slow than usual. And yesterday, during some basic operations on the server,
such as "ls", "cp", "ifconfig". Suddenly, there appeared a I/O error, then
the server died.

The RAID controller is:
0000:02:03.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID (rev
01)
And there are a RAID-5 logical disk via three 146G SCSI physical disks.

After boot the server, we have entered the RAID controller BIOS, found all
the physical disks has been the "FAILED/OFFLINE" situation.  Then we forced
the status of HD to ONLINE status.
Then we boot the system via a KNOPPIX cd, and the partition table detected
by fdisk look likes:

[EMAIL PROTECTED] fdisk -l
Warning: ignoring extra data in partition table 5
Warning: ignoring extra data in partition table 5
Warning: ignoring extra data in partition table 5

Disk /dev/sda: 293.6 GB, 293628542976 bytes
255 heads, 63 sectors/track, 35698 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1          13      104391   83  Linux

/dev/sda5   ?        1675        2071     3177836+  dd  Unknown
In fact, there should be sda5 and sda6, i guess cylinder 1289-1675 should be
the sda5 - swap partition. And the rest should be the sda6.

The first three partitions could mounted successfully, and sda contained NO
data which should be the boot partition. But sda2 and sda3 which should be
root partition and /var partition contained NO data too, but there are so
many files in the folder "lost+found".

We have used GUI parted, parted, testdisk, gpart and some other disk detect
tools to the scan the disk and try to find out the correct partition tables,
but no results.

So i post this problem here to ask for some advices.
Could someone pick me up?

Thanks in advance.

Penghui Wang.
