Gspeed ES Pro RAID keeps disappearing from Mac, have to re-initialize!

[Jesse Schluntz]

here is my Raid:

When this whole issue began, I spoke to G Tech on a support call, went through the problems, and they concluded there wasn’t anything on my end indicating a problem with the actual raid hardware. That being said, they’re ready to send me a new drive if these final eliminations point to that.

I’m currently rebuilding the raid again after installing a new ATTO card. If all 10TB load up and I can edit for a few days with no issues, the card was most likely the issue. If the raid disappears again, I’ll try the new cable I just received. If that doesn’t work, I’ll pull the trigger on the replacement raid.

The bottom line is everyone around me says “it sounds like this is the problem” or “the problem is for sure that”, but nobody has been proven right and my system is still paralyzed.

I can’t wait until I can declare who was right, believe me!

HDs are all blue. If one of them goes out, the raid literally sounds an alarm. I’ve heard it before when I had a heat issue months ago.

I believe you, and for sure you are not the only one with similar problems.
Try this:
New Configuration Raid 5
Just put some files on it.
Let’s say 300 GB
Try to work around a little with the raid.
If one of the drives go on red you have found the problem. It’s a drive. Replace the drive, your problem is found. If the array disappears with the new cable you need a new G-raid (Hardware.

Heat issue? This is definitely Raid hardware. Perhaps one of the fans is not working properly. If one drive fails, you have to replace it. Especially when you are on Raid 0. Raid 0 is harakiri. We have not one raid working on 0. Since 10 years.

the story unfolds as you release details. Why on earth are you using RAID 0, with an ATTO R680 card ? The whole point is that if a drive fails, you don’t lose all your data. You MUST use RAID 5 for this system.

You previously said that you are getting a new cable and enclosure from G-Tech. I am very glad about this (and surprised at the cooperation). This will hopefully resolve your issues. I doubt it’s the ATTO card very very much.

I agree with bob!

Err…. the first line of my first post says I’m configured raid 0 with back ups. not sure how you both missed that.

Regardless of configuration, the gear no-worky.

I’ll let you guys know what happens!

My last recommondation, and I’m very serious about this:
It is the raid controller in the G-Raid.

Bob, I don’t mean to be adversarial: RAID5 is not a must on a 4-drive box, especially when there are multiple levels of backup:

The controller is a card that’s installed on my tower. The controller connects to my G raid via mini SAS cable.
