Title: Manage hard disks
Post by: cipandales on August 20, 2008, 04:59:36 PM

Hi all !

I have 2 hard disks. Same sizes. I think Sme Server makes raid or something, but I need to access the secondary hard disk as well.
Where/which is the folder where the disk is mounted ?
How can i use it to make ibays on it ?


With fdisk -l | more i have this:

Disk /dev/md1 doesn't contain a valid partition table
Disk /dev/md2 doesn't contain a valid partition table
Disk /dev/dm-0 doesn't contain a valid partition table
Disk /dev/dm-1 doesn't contain a valid partition table

Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Have you read the Manual?

Install sme with one disk only.
Then when all done, connect the second disk and use the Howto that tells you how to add a second disk. Search the Howto page for this (linked at top of forums)

They are already in use. That is the trick with RAID.

You might wanna test next scenario's:

1: Power down.
2: Disconnect primairy master. (hda)
3: Connect primairy slave as primairy master. 
4: Powerup!

Magic!

That is what RAID does! As CharlieBrady says: Read the Manual(s)...
Note; step 3 might not even be necessairy depending on hardware ...
