I ordered a new server 2 weeks ago, and had some trouble with stability.
Yesterday I removed auditd as I've read that CPanel had problems with it.

It hasn't crashed since, but today I noticed that my server has no Swap space/ partition.

In top it says:

CODE

Swap: 0k av, 0k used, 0k free

I checked /etc/fstab, which looks normal:

CODE

/dev/hda3 / ext3 defaults,usrquota 1 1

/dev/hda1 /boot ext3 defaults 1 2

none /dev/pts devpts gid=5,mode=620 0 0

none /proc proc defaults 0 0

none /dev/shm tmpfs defaults 0 0

/dev/hda2 swap swap defaults 0 0

/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

/dev/cdrom /mnt/cdrom udf,iso9660 noauto,owner,kudzu,ro 0 0

/dev/hdb1 /hdd2 ext3 defaults,usrquota 1 2

/dev/hda2 is mounted as swap and /dev/hda3 is mounted as /

But when I do "fdisk -l /dev/hda" I see this:

CODE

Disk /dev/hda: 80.0 GB, 80000000000 bytes

255 heads, 63 sectors/track, 9726 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

/dev/hda1 * 1 13 104391 83 Linux

/dev/hda2 14 9471 75971385 83 Linux

/dev/hda3 9472 9726 2048287+ 82 Linux swap

/dev/hda3 is type swap? This doesn't look right to me.
How do I correct this without losing important data on hda3?
Should I make a trouble ticket, or do you guys have other options for me.

Thanks in advance.

What do you get from running

df -h

cat /etc/mtab

df -h returns:

CODE

Filesystem Size Used Avail Use% Mounted on

/dev/hda3 72G 28G 40G 42% /

/dev/hda1 99M 15M 80M 16% /boot

none 501M 0 501M 0% /dev/shm

/dev/hdb1 74G 26G 45G 37% /hdd2

And cat /etc/mtab returns:

CODE

/dev/hda3 / ext3 rw,usrquota 0 0

none /proc proc rw 0 0

none /dev/pts devpts rw,gid=5,mode=620 0 0

usbdevfs /proc/bus/usb usbdevfs rw 0 0

/dev/hda1 /boot ext3 rw 0 0

none /dev/shm tmpfs rw 0 0

/dev/hdb1 /hdd2 ext3 rw,usrquota 0 0

in /var/log/boot.log it states:

CODE

swapon: swapon: /dev/hda2: Device or resource busy

I hope you can help me.

The server crashed again this morning, so the removal of auditd didn't solve the problem.

Does anyone have tips on how to correct the partitions?

That sure looks like there's some kind of problem with the image to me, with the conflicting reports from fdisk and df. If it were my server, I'd get an off-server backup done ASAP and get a restore.

i just see a problem here, in /etc/fstab hda2 is swap. and in your partition definitions(fdisk) swap is hda3.. that dosent looks right to me..

Generally fdisk is correct on these issues.

Looks like your drive was not parititoned properly.

/dev/hda3 9472 9726 2048287+ 82 Linux swap

Is listed as linux swap but is mounted as /

My advise is to make a backup and then restore. You could try to fix /dev/hda3 but it may fail, so best to have a backup.

1) Someone wrongly partition the disk and made the /dev/hda3 as 82(linux swap), You can put an ext3 filesystem on a partition that's marked with type 82 (Linux swap) in fdisk.

2) I don't think your server crash because of that, possible reasons could be

1) Since you dont have swap space, check the memory, because when the server run out of memory it crashes

11) Some time the stock redhat kernel wich RHEL has some problem it crashed on random time, please rebuild your kernel, mostly that will fix.

hope that helps,
