I have a Mac Mini that I plan to use as a simple file server with a 2TB external disk. I would like to be able to add future external disks to grow the original 2TB volume I create to 4TB, 6TB, etc. using RAID.
I know it is possible to add disks to a concatenated RAID set without destroying the data on the disks already in the set, but I cannot get Disk Utility to let me create a single-disk concatenated RAID set.
I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.

My iMac has been crashing a lot lately and finally it's hard drive just up and failed. I have been doing hourly Time Machine backups to a concatenated RAID set (2 USB drives of 1 TB each). However, I think the iMac crashed while backing up and hosed the RAID controller.I've since plugged the two disks of the RAID into my MacBook Pro to see if I can repair them. I can see the individual disks of the RAID in Disk Utility. I can even verify and repair them. But i can't do that with the RAID in the sidebar, and it won't mount on the desktop. When I try to eject it from the DIsk Utility file menu, it says disks are in use.
I'm pretty sure my data on the two disks is intact, but I can't seem to get the RAID to mount as the single concatenated set on a desktop, which makes it inaccessble. Is there a way to repair the JBOD RAID without losing all my data, so I can then restore from the latest backup to my hosed iMac?

I just got a 2nd caviar black 1tb and I'm goin to be setting up raid with another drive.. I have data on my current 1tb which is backed up with time machine. what do I have to do to get the drives workin in raid? I'm lookin to have a faster write speed since I need the raid setup. Since I will be using the 2 drives for my data and a photoshop scratch disk, should I create a partition for the scratch disk? I've seen some say yes.. Some that said no but without reason.What r the pros/cons to partitionin the drive?

View 4 Replies View RelatedI currently have a 1TB and a 500GB disk as a concatenated disk on my computer.My iTunes library is stored on there and it sometimes takes a second or so to load up my library.As my library is fast approaching 1TB, what would be my best course of action?The Samsung Spinpoint F3 1TB is on ebuyer for ?47 at the moment, which is a pretty nice price. Should I give up on Apple's software solution and look for a raid card that will give me RAID-0 for two 1TB disks?What would give the best performance? I can't afford a Drobo and don't want anything plugged in externally if possible.

I'm concidering 2 of either the WD thunderbolt duo 6TB or the LaCie 2Big Thunderbolt 6TB. I want to set each 2disk unit to RAID 1 and then srtipe them as RAID0 accross thunderbolt to hopefully result in one striped and mirrored 6TB RAID volume
I'm hoping yes because i've seen 4 of the WB unit daisychained as one huge RAID0 but I'd like the redundancy. also i want the resultant volume in exFAT as I am constantly jumping between OSX and Win 7

Difficulty deciding between 1 or 2. Unsure about real world performance gain of 2. No experience with SSDs or RAID 0. Worried about alignment and sleep/hibernate issues. Stock 5400rpm 320GB will go inside eSATA enclosure. Does anybody have a good eSATA ExpressCard/34 to recommend? I don't care about the SuperDrive. But I'll keep it for Care warranty purposes.

I have just finished setting up my first Lion Server from scratch on a Mac Mini with dual 500GB Drives which I set up as RAID 1. I have the server exactly as I want it, and before the users start logging on and it gets all screwed up I would like to create a disk image of it so that I could reinstall if necessary w/o having to start from scratch.
Is the process of creating a disk image for a RAID 1 any different than that of a disk image from a single drive set up? Will Disk utility just see this as a single volume or will it want to create a disk image of the entire RAID? i.e will the disk image be 1 TB (500 GB x 2)? And when it comes to reimaging my RAID, will I just recreate a RAID 1 and be able to write to it from that disk image?
i have Snow Leopard running in a RAID, and just a separate single drive installed for windows 7. Problem is, when i try to go to bootcamp assistant, it tells me that RAIDS aren't supported in bootcamp. I don't want to install it on my raid, just on the other single drive. Does anyone know a workaround or how to do this?

View 2 Replies View RelatedI'm still working out the details on purchasing a new MacPro. My Apple sales rep tells me that I can greatly increase the launch speed of applications and the system OS by purchasing 2 hard drives and using Disk Utility to stripe them together into a "software RAID". They claim it will be faster and more reliable than a single SSD. I know I've asked this question before, but the answers were over my head. I don't know anything about SATA raid cards, or SSD's except for their benefits. But I'm pretty sure I can stripe two drives together and make a software RAID.
