Topic: Cannot mount additional disk to sme 7.3 following howto, device busy

[jptechnical]

Followed these instructions (not tough though... pretty standard linux, the telinit 1 was new to me though) http://wiki.contribs.org/AddExtraHardDisk, I also reviewed this one http://wiki.contribs.org/AddExtraHardDisk_-_SCSI and didn't see anything related to this issue.

I have searched extensively through the forums and found nothing else I haven't tried. All the forum posts point back to the howto or were used to update the howto. I searched the wiki and only found the one howto for adding an additional disk, nothing about adding an additional array.

When mounting the disk, I always get device busy errors.

I have a Dell PowerEdge 400sc with 2x300gig sata drives (sda,sdb) in md0,1 and 2x250gig pata drives in hda,hdc that I can't mount and finally an 80gig usb drive at sdc which mounts fine. I originally installed on the 2 sata drives and the raid was magically setup (I really like sme!), so I didn't have to do anything there. I added the two pata drives after I had everything installed and working to my liking... svn repos, ibays, backup contribs and the like just how I want it.

I know that the two pata drives do not show up in the bios... so I will check the termination... but they are both set to master, I will set to CS or nothing and see if it makes any difference. But it is crazy that fdisk and mkfs.ext3 can both read and write to the drive just fine, I just can't mount it.

Ideally, I would like to make another raid (md3) and mount it in an ibay, but I would be fine with mounting an individual drive in an ibay and then rsync every night to the other drive.

fdisk -l, I followed the directions from the howto, and in addition did it another way I was familiar with, so there might be some inconsistencies there.

I changed the jumper on the hard drives, they are now recognized by the bios. However, it still will not mount the drives, says busy.

Any ideas?

I changed the drives out with two different drives, 2x160gig pata drives. They are seen in the bios, fdisk sees them and can create partitions, mkfs.ext3 can make a filesystem on them... but nothing can mount them.

I have hit a wall. Any ideas out there?
