[SOLVED] second hard drive showing first drive / when mounted

newbeliever · 01-06-2015, 01:08 PM

On my current system I have drives sda, sdb, sdc; 1TB, 1.5TB, 1.5TB respectively.
SATA drive a is where I installed the OS and the other SATA drives b and c are from an old system that was linux software mirror, something I was using to play and learn. Now I have added b and c to my current system and before doing so I stopped the mirror and removed the partitions. I added the drives to my current system and used cfdisk to create one partition on each and then mounted the new drives. I then run ls and I see bin/....etc. listed in the new drive. Is this normal or when I create the new drive partitions should I use Logical instead of Primary.

Is there a way to get my drives back to non raid that I have missed doing?

Thanks

Deleting then creating partition(s) doesn't do anything to the under-lying data - including the RAID meta-data. So when you mount /dev/sd[bc] everything reappears. If you do a mkfs on the partition you created on each of those drives (prior to mounting), you should be ok. Note this will delete all that data, so be sure before you proceed.

Assignment of /dev block devices is done by kernel and or udev. Also mounting the disks is upto you. I can't understand your problem correctly? Please clarify.

yes, would be nice to explain:

How did you add, what did you make with cfdisk, what can be seen in bin?
How your drives are mounted now?

Thank you all for posting. I was able to solve my issue as explained below:

Computer #1 I had setup with one drive. Computer #2 I had setup with three drives in raid configuration.
Computer #2 was partitioned as / raid1; /home raid5. One drive failed on this system.
I then decided to add the other two drives to computer #1 and do a fresh install. I disabled the mirror on the two new drives before moving over to new system and then used cfdisk to repartition the drive, but what I actually done was just increase the size of my first partition to consume the entire drive area. According to what I have found and also the previous post by syg00 the data was still there, and what I was seeing was the / of my previous install. That made more sense then.

I then learned alot about drives and switched to gdisk to handle my partitioning do to my new learned info about BIOS and drive geometry.

Thank you.
