Hi,
I have 2 40GB internal ATA drives on my Linux RedHat 9 pc.

disk 1 has /, /boot, /dev/shm
disk 2 had /backups
.
.

I would use find to copy files from disk1 to disk2. You know make backups in case of a disk crash or need to reload the OS!

It figures - due to a major problem I had to format disk 1 and reload RedHat 9 from the source RPMs. I made sure I disconnected the power and ribbon cable from disk2!

After the OS reload I completed the following

plugged the power and ribbon cable back into disk 2. The command dmesg
indicates it acknowleges both disks hda and hdb.

created the mount point

mkdir /backups

Added the following to /etc/fstab

/dev/hdb1 /backups ext3 defaults 1 1

tried to mount up the device

mount /backups

mount replies

mount: wrong fs type, bad option, bad superblock on /dev/hdb1, or too many mounted file systems


As a test I swapped out disk 2 with another spare, ran a mkfs and it mounted fine as /backups. My gut tells me this version of Linux can't access a filesystem without 1st running a mkfs to the device. I pray this is not the case because I have a load of data on this disk like my bookmarks, email ....

Thank you for your help.

By doing this, you're telling the system to mount that partition upon boot.
Possibly because it was already mounted.
No, that doesn't sound right. An ext3 filesystem is an ext3 filesystem. It doesn't matter who created it, you should be able to access it on anything.

One thing: You might want to try upgrading to a newer version, because RH9 is so old that it is no longer supported. After RH9, they renamed the consumer version "Fedora" which has just recently hit version 5. Try it, I'm sure you'll like it.

Hi,
Thx for your help.

Some additional info.

Hi,

The OS appears to acknowledge both hard drives hda and hdb.
hdb is my /backups filesystem that was working fine before I had to format the entire hda disk and reload Linx.


Some further information from dmesg.

Hi,
I dowloaded slax-server-5.1.6.150 burned the iso image to a CD-R using GnomeToaster then booted the CD.
slax automatically mounted up both disks hda and hdb (my backup drive that I could not mount after I had to reload Red Hat 9). cpio'ed the data from the backup drive to hda then rebooted Red Hat 9.
A fdisk /dev/hdb, mkfs -t extt3 /dev/hdb , and update to /etc/fstab
/dev/hdb /backups ext3 defaults 0 0
am back in business with all my goodies
Now to download the latest version of Fedora ... bye bye Red Hat 9.
Once again, thx for the tip on slax. Good Stuff!

Best Wishes
Bob
