Okay, so i’ve had a 1TB external USB for a while which has been formatted for OS X use (HFS+). I’ve been doing a lot of work on Linux (Ubunut 14.04) recently and wanted an easy, fast way to be able to read/write on both operating systems. I dabbled with this briefly a while back but was unsuccessful, but recently I found a little trick to enable read / write on both OS’s! This may seem like basic setup to some, but judging from the amount of forum posts i’ve read on this, it does seem to fox a lot of people…
NOTE: there is a caveat to this; I don’t share this drive with any other computers. If you move a drive between machines then this solution isn’t for you. Read on to find out how to enable this!
I’ve spent ages trying to get automounting of a RAID array to work; and after many failings I now have it working, so I figured now would be a good time to document the process.
Now i’ll assume you have a working software RAID array (or a standard RAID Array) which you can manually mount.
Step 1 – Get the correct UUID
A lot of the guides to this tell you to find the UUID of the RAID array by using ‘mdadm –detail -scan’ – this is WRONG! It took me a while to find that the correct UUID for your array can be found by using the blkid command (blkid is a command-line utility to locate/print block device attributes):
Once you have the correct UUID you can move on…
Well after monkeying about with a busted 11.10 installation (call it a learning curve with Linux); I decided to reinstall the OS from fresh. I have 4x2TB drives utilising Ubuntu’s FakeRAID (software RAID), along with a 500Gb OS drive (the target for my refresh).
TL;DR – solution to this problem is at bottom of this post;
