Weird hardisk problem...

[webfuture]

I have a server with a raid 5 attached where I boot from and another SATA attached to the motherboard that I want mounted to /backup...

This is fdisk -l

Disk /dev/sda: 319.9 GB, 319977160704 bytes
255 heads, 63 sectors/track, 38901 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         131     1052226   82  Linux swap
/dev/sda2   *         132       38899   311403960   83  Linux

Disk /dev/sdb: 300.0 GB, 300069052416 bytes
255 heads, 63 sectors/track, 36481 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       36474   292977373+  83  Linux

and fstab

/dev/sda2            /                    reiserfs   acl,user_xattr        1 1
/dev/sda1            swap                 swap       pri=42                0 0

/dev/cdrecorder      /media/cdrecorder    subfs      fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0
/dev/fd0             /media/floppy        subfs      fs=floppyfss,procuid,nodev,nosuid,sync 0 0
#/dev/sdb1            /backup              reiserfs   acl,user_xattr        1 2

The problem is when I uncomment the line in fstab where I have /dev/sdb1 (my SATA HD). The system won't boot because it won't find the drive and can't fsck... When I go into maintenance mode and do fdisk -l, the drive is not there.

When I comment that line and boot, everthing is ok, fdisk -l show the drive and I can mount manually.

This is df when I mount manually

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda2            311394396   1479112 309915284   1% /
tmpfs                  4152772         8   4152764   1% /dev/shm
/dev/sdb1            292968396     32840 292935556   1% /backup

So I cannot mount that drive at boot time !!! anyone has a clue...

Thanks

I'm not sure, but could it be that the drive is set up as a primary bootable drive? Maybe the jumpers on the drive are set up as a primary instead of slave?

Just a guess...

In the BIOS, the boot drive is the raid array and that works fine... This is an SATA drive connected to the motherboard, not sure what I can control there.

Thanks anyway

looks like it is a scsi device so check the scsi ID's make sure they are not the same

 

[webfuture]

This is a SATA drive, probably detected has SCSI by linux for some reason... Is there a way to change the SCSI id on an SATA drive ?

Like I said, I have a raid controler detected has /dev/sda and an SATA drive detected has /dev/sdb.

I can manually mount /dev/sdb but not from fstab at boot time.

Anymore clues?

Thanks

Found the problem...

This module ata_piix was not loaded at boot time.

Now everything is OK.
