Hi, I currently am using softraid to run a RAID 1, mirrored volume, to store my data. I have two 4TB hard drives each with a single partition on them named "HD2", and they are installed in a thunderbay 4 external enclosure.
I was hoping to create a new partition on my hard disk using the available free space, and then use that partition as a time machine backup disk, but I don't see a way to do this. In disk utility, if I select "HD2", the "partition" button is greyed out. I don't see a way in softraid to create a new partition on a disk using the available free space
I also had a few questions about how softraid volumes work with mac's that don't have softraid installed
1. If I end up having to get a new mac or wipe my mac's boot drive, on a fresh install of osx, will time machine recognize a timemachine backup stored on a softraid volume? Do I need to install softraid before I can restore from a timemachine backup?
2. If I plugin my thunderbay enclosure containing my softraid disks into a mac that doesn't have softraid installed, are my disks readable? If I copy data onto those drives using that other mac, are they still mirrored as a raid?
Thanks for all your help.

Disk Utility taught an entire generation of users that partition = volume and initialize = initialize and create volume.
With SoftRAID you initialize disks. That puts disks into the SoftRAID format, but there are no volumes on the disks yet. Then you create the volumes you want, the RAID type you want and the size you want.
There is no concept of "partitioning volumes" in SoftRAID. Also, never use Disk Utility to try to manage a SoftRAID volume. Disk Utility does not know what to do and can mess things up. Use SoftRAID to manage SoftRAID disks.
Read the online help about managing volumes to understand more.
to reply to your questions:
Yes, OS X recognizes a Time machine backup with 10.9 (for RAID 0/1) and 10.10 and later for all other RAID volume types.
Yes volumes will mount as above, 10.9 (for RAID 0/1) and 10.10 and later for all other RAID volume types. there is a bundled, limited feature driver included with all versions of OS X.
