G-Raid 8TB working but not mounting

My G-Raid 8TB (running as a single disk) seems to be working OK but not mounting coxrrectlyl.
this seems to have happened after the MAC told me it had ejected unespectebly…

Disk Warrior is able to ‘see’ it and I checked the HD and it seems to be OK
Disk Utility does not see the mounted drive (see screenshot below) - with spinning ‘loading disks’ running continuously

the overall disk seems to be visible (see screenshot below) but this does not let me carry out first aid on the disk

I’ve tried the usual.
Restarted the iMac (3.4GHz core i7, 32GB ram, OSX 10.11.6)
Connected the Drive directly to the Mac via Thunderbolt cable
tried a different cable
all to no avail.

any ideas?

Joe

Joe,

You mentioned that Disk Warrior said the drive looks fine but did you actually try clicking the Rebuild button? It looks like it still needs to be rebuilt in order for it to restore the mount point and accessibility of the drive.

Thanks for quick reply Rydia,
I did click on rebuild button, it was at 8/10 and its now 10/10 see image below.
I’ll try it one more time.
Joe

Just rebuilt again, even tho Disk Warrior said there were no problems. and have the same result.

  • 10/10 on DW
  • seems to run OK, can access files, add files
    …but now I’m worried! is the disk about to fail?
    any ideas as to what to do next?
    thanks,
    Joe

further update.

(by the way running on iMac 3.4 GHz Intel Core i7 with 32 GB ram on os 10.11.6)

Ran Daisy Disk on and seems fine (see screenshot below)
and also Hardware diagnostics on Disk Warrior, and it seems fine (see text below)
still have same issue with Disk utility as per first screenshot in this post thread.
thanks for help,
Joe

Because you’re using one of our G-RAID w/ Thunderbolt drives on 10.11 you will have issues in Disk Utility. Apple removed the ability to manage software RAID drives within Disk Utility on 10.11. As long as it is mounting and your other diagnostics are showing OK the device will be fine.

that’s good news Rydia, thanks!
I like the G-raid very much.
I’m planning to get a 12 TB raid device to run in Raid 1, 2x6tb. will I be able to do that in 10.11?
thanks!
Joe

If you are going to move onto a new G-RAID that supports RAID1 and configuration within the OS would be our G-RAID Removable with Thunderbolt 2. Here: http://www.g-technology.com/products/g-raid-thunderbolt-2

thanks Rydia,
I have another question. I have a La Cie 4tb raid drive configured as Raid 1 for my iTunes library.
I can see this on Disc utility and can carry out ‘first aid’ see images below. but I can’t on my G-Raid 8? only difference I see is that I’m running this disk as a simple 8TB rather Raid 1 2x4 TB.
Why does OSX see (and can repair) one but not the other?
Joe

G-Raid - first aid greyed out below

LaCie 4TB - can see and use first aid on both aspects of Disk - see below

Your other drive uses a hardware RAID controller so it is handled by itself not the Disk Utility. Because the version of the G-RAID you have is a software RAID 10.11 can’t manage it. This includes First Aid.
