CLOSED: BIOS RAID question

[DABurt]

I happily used Amahi on Fedora 14 for years without trouble, but recently decided to do a fresh install of Amahi 7. I am going with 7 because I understand Amahi 8 cannot be installed on a 32 bit processor, and because the two apps I am primarily interested in running are not live on 8.

I know almost nothing about Linux, but do know how to follow directions.

I installed on an old Dell Dimension 8400, which has BIOS RAID support. My Fedora 14 build was simply two 500GB HDD in RAID1 array under BIOS. For the new install, I decided to add a 60GB SDD to install Amahi on, with boot, swap, and root partitions, and use the 500GB RAID1 array for shares.

I started with just the SDD installed, planning to add the RAID HDDs after, per the wiki. When I added the HDDs, although the BIOS was showing them in RAID1, it seemed that Fedora saw them as two separate disks, not in array. I reinstalled Fedora/Amahi with the HDDs installed. Now I am not sure if the RAID array is recognized; looks like it is, but I'm not sure how to proceed to mount it.

fdisk -l gives this output:

Disk /dev/sda: 500.1 GB, 500107862016 bytes, 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes


Disk /dev/sdb: 500.1 GB, 500107862016 bytes, 976773168 sectors

Disk /dev/md126: 500.1 GB, 500107575296 bytes, 976772608 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

sda and sdb are obviously the two HDDs, sdc the SDD system disk. I guess that md126 is what Fedora recognizes as the RAID array; right? But ls -l /dev/disk/by-id/ gives the following output:

If md126 is the RAID array, what is md127?

If md126 is the RAID array, can I just follow the wiki instructions for adding a disk using md126 as the name of the device to be mounted?

What are the apps that are not available for Amahi 8 that you need?

BTW, please understand we no longer provide any support for Amahi 7. There will be no updates to apps, the platform, or new apps released.

If you are ok with that, great. Just wanted to make you aware since Fedora 19 was retired and OS updates have ceased.

The two apps are IPsec VPN, and Crashplan. Although, as I understand it, I cannot use Amahi 8 anyway because I have a 32-bit processor.

I understand. If/when the need arises, I will upgrade my hardware and reinstall later. Hopefully, installing the OS on a separate disk makes that easier.

So I went ahead and tried following the wiki instructions to mount what I think is the RAID array (md126). The updated /etc/fstab and the outcome (not successful) are attached.

Any suggestions?

[DABurt]

OK, looks like I missed a step; I forgot to format the partition after creating it.

I started over with the steps in the wiki, and it now appears to be mounted.

Thanks for your attention, sorry to have wasted your time.

Sounds like you got things sorted out. Sorry I was not much help, but I have no experience with RAID.
