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 Warning: invalid flag 0xffffaa0a of partition table 5 will be corrected by w(rite) 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/sda2 14 650 5116702+ 83 Linux /dev/sda3 651 1287 5116702+ 83 Linux /dev/sda4 1288 35698 276406357+ 5 Extended /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. -- Wang Penghui http://www.extmail.org http://www.postfix.org.cn
