Because your hard drive is going bad, that's why. Replace it.

Before replacing the harddisk I would recommend to download the manufacturer's diagnosis tool and test the disk.

this server have 6 hard disks , how i can know which one is the bad one ??

If you have errors on the swap partition I would test the one with the swap partition. If this is a RAID setup I would test them all.

no it is swap partitions , can you please tell me which is the best tool to test them ?

You get your errors on the swap partition. Look up in your /etc/fstab on which disk the swap partition is, then use the diagnosis tool that is provided by the manufacturer of that disk.

it is ubuntu server so what is the command ???
this my /etc/fstab

Code:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    nodev,noexec,nosuid 0       0
# / was on /dev/sda1 during installation

As we can see here your swap partition is on /dev/sda, which is usually tghe first disk in the system. There is no guarantee, but usually the first disk in the system is the one on the first SATA port on the motherboard.

sda is my system hard disk and the others is for file storage , so what i should do now ??

TobiSGD · 09-28-2012, 08:12 AM

As I said two times already, download the manufacturer's diagnosis tool and test the disk with it.

!! hack-back !! · 09-28-2012, 09:00 AM

as you said : download the manufacturer's diagnosis tool and test the disk with it
what is the package name for ubuntu please ?
thanks

TobiSGD · 09-28-2012, 09:04 AM

There is no package for Ubuntu and even there would be, how should I know the manufacturer of your harddisk?. Go to the manufacturer's website, download the tool, burn it to a CD and boot the system from it.
