I own a PowerMac G3 with 2 hard drive disks. One is a 20gb and the other is a 40gb. I would like to combine the disks with a pseudoRAID type called JBOD. JBOD stands for 'just a bunch of disks.' It's not really RAID. What I'm after is to see these two drives as one 60gb drive. Is that possible? I'm running Mac OS X Tiger.

I have a hex with 4x 2tb istalled on regular Mac bays and one ssd on the optical bay. They(4x 2tb) are configured as a giant 8tb JBOD. Now I purchased 3x 3tb and a sata card for the extra sata ports. Is there a way to create another JBOD with the the new 3tb drives and in the near future get rid of 2tb ones and put the 3x 3tbs on the regular Mac ports without loosing the data. All JBOD will be and was created using Snow Leopard's disk utility.
View 5 Replies View RelatedI was reading online that RAID1 is not a very reliable backup method, and is primarily for speedy recovery, over true reliability. I want to buy a dual-bay enclosure; something like the Icy Dock MB662UEAB-2S; [URL] People say they the best thing to do is get 2 separate external drives and backup with one, and use the other to make a copy of the backup drive, so you have 2 separate drives. Would it be fine to just to put 2x1TB drives into the enclosure, setup as JBOD then use Superduper to clone drive A onto drive B. Or is this not a good idea. Also can I stick a single drive into the IcyDock now and buy a second one later, as im a little shot of money at them moment. I got a 500GB old schol hardrive i could use for redundancy for the next 6 months, before i add a second drive into the enclosure.
View 2 Replies View Relatedso here is my question/dilemma. I had a server running in RAID0 that had a drive fail so I lost everything. I will be using a large portion of the storage simply to hold media to stream to my TV, so having one large filesystem doesn't give me any benefits. Should I just set up the mac pro with every drive having its own share or should i RAID0 my drives? Im leaning towards a JBOD solution but someone more experienced may be able to give me a better point of view.
View 15 Replies View RelatedSo, please welcome me back. After 15 years (I had Mac Plus, LC and Quadra 650), I am back from the darkside. Bought myself a Mac Pro today. Yeah - I probably should have waited for nehalem, but my PC was getting flaky. Time for the every 9 month wipe/reload and I just didn't want to go through that again, so I jumped. Tomorrow I am moving drives into the MP. My questions is specifically about partitioning and Raid. I typically partition my drives about 1/2 way down the middle and give the 1st partition to high performance needs and leave the second for infrequent use of backups and storage.
Lets assume I have two WD6400AAKS (I have three actually). Ideally, I'd like to partition them like this:
WD1 Partition 1A (200GB) Partition 1B (400GB)
WD2 Partition 2A (200GB) Partition 2B (400GB)
Then (using Soft Raid)
- Config partition 1A and 2A as Raid 0 Striped (giving me 400GB high performance)
- And config partition 1B and 2B as Raid 1 Mirrored (giving me 400GB redundant backup)
(Yes - of course I don't want to access the mirrored drives when expecting high performance from the striped drives). I assume that once the drives are partitioned, the Soft Raid will simply see them as four different drives allowing me to configure them as described. But before dropping a few hours into this, I thought I'd let all you raid/hard drive experts give your opinion.
"My name is Shaun, and I am a mac-aholic"
I inserted 4 new 3TB disks into the bays of my Mac Pro (2012), and there is no RAID option for them.
How I got here:
Inserted the WD Red drives, and they were not initiated.
I "erased" the drives, gave them names, and they appear in Disk Utility in grey drives.
Went to set up the RAID, and move the drives into the RAID, but got an error that they could not be used.
It appears to me that disk utility is not allowing me to fully use those drives. I Have created RAID drives before with no issue in RAID1 with 3TB drives before on this machine. Am perplexed, I thought this to be the easy and simple part of my upgrade odyssey! Did I screw up the initialization? On all FOUR drives?
Now, if I click on the drives, the RAID option does not present itself.
FWIW, I am using OS X 10.9.5, on Mac Pro 5,1. I boot from PCIe card. My end goal is to create a 4-disk RAID 10 using the four SATA connections on the MP.
I have a Early 2008 Mac Pro. I have the Apple Hardware Raid Card Installed. I have 4 2TB disks installed. Currently I've got the system disk setup in Bay 1 as a single disk. Then I have the disks in bays 2 through 4 setup as a raid 5. I've been thinking that I might be better off to make all 4 disks into a raid 5 array and then just make volumes for the system disk and my work disk. My goal is to have a system volume an a scratch/work volume for image and video editing.
View 1 Replies View RelatedCan I just remove one of the drives and what are the consequences of the removal. I would like to go from a mirrored raid to a carbon copy of the disk which would be updated weekly and use Time Machine in between.
Do I open up a can of worms - my suspicion is that if I want to do that I'll have to reformat the RAID with the loss of all data.
Any workaround short of making a copy, removing the raid and restoring the data?
I'm about to get a Mac Mini Server for audio, video, and graphic production, in addition to everyday productivity use. If in the same situation, which would you prefer?
1) to stripe (Raid 0) the two internal disks, or
2) use one as the install/OS disk and the other as the data/scratch disk?
(...assuming you have a 1TB external backup drive, and find FW800 to be much slower than internal SATA for a data/scratch disk).
I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.

The Apple Store employee I talked to said I should make an appointment at the Genius Bar and they'll do a wipe and reinstall for me, but I'm not interested in putting much more money into this since I'm giving it to a friend as a favor (hers just died). Any suggestions for how to get a copy of the right OS and all the iLife software, too? It has Tiger, but I could put Leopard on it, if that's easier to get a hold of.

View 1 Replies View RelatedI'm relatively new to Macs and I wanted to try a clean install (or erase and install) on my ibook. I recently purchased a MBP and since Leopard is on the horizon, I wanted to do a "trial run" of installing an updated operating system. I know that you can just hit update instead of doing a clean install, but I've been reading that things run better when you do a fresh install. My old ibook still has Panther on it and I figured I could try to install Tiger on it from my MBP disks.
I know that this represents a violation of the license, but I thought it would be worth it to ensure that I don't make any major mistakes when I'm doing the same procedure with my brand new MBP when Leopard gets released. When I tried booting from the disk from my ibook I got a kernel panic which I interpreted as a sign that it was not a good idea so I abandoned the project. Now every time I try to start my ibook I get another kernel panic and I'm afraid I just broke my old computer.
I was wondering if I could install 2 ssds and raid 0 on my 12'' powerbook/ 15'' MBP 2007 - taking out the superdrive and installing the MCE optibay I very rarely use the optical drive so I won't have much use for it. Regarding the powerbook, I'm having trouble finding a good IDE SSD so I'm looking at this transcend model
View 7 Replies View RelatedI have a PowerMac G4 I'd like to use as an "experimental" backup machine. I am looking to try and make a RAID setup in it, and I'm no expert with that. I'm wondering if this is even possible, first. I'm also wondering if I can do this with 2 40 gb drives and a 20 gb drive. I want to make it so it appears as 1 drive. I'd be using tiger and a software RAID if that is of any relevance.

Does anyone have an OWC Mercury Elite-Al Pro Qx2? If so any idea how to get it into JBOD mode? In the book, it shows to set the selector to 0 if using a software raid, however if I do that the rebuild light just blinks (why when it shouldn't be in a raid?) and does nothing even after 36 hours. All other raid modes that I have tested on this work flawlessly.

View 3 Replies View RelatedI just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)
My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.
