MP 1,1-5,1 Striped Raid MacPro 4,1 Mojave

[markapplelover]

I have a Macpro 4,1 with a Striped RAID of 4x4TB drives = 16GB volume. Beginner with this, used to Windows where if one fails I can add a spare and then remove the bad one but can not find anywhere on how to do this in a mac. Any suggestions?

Are you using SOFTRAID to configure a RAID 10 or RAID 5?

sorry I see you said a 16GB volume.. means no redundancy.. no option to remove bad and replace under RAID 0. Go to softraid dotcom for effective instructions to set up your macOS RAID

i used disk utility

OK.. I will need a bit more information. The senior contributors on this forum encouraged me to describe system specs in my signature (including macOS release) and I suggest you do the same. You have a tag in the opening post that says 'raid 5' but you describe..

a Striped RAID of 4x4TB drives = 16GB volume.

which is raid 0.
I directed you to SoftRAID website for 2 reasons, first, they have a very good description of stripes, mirrors and blends (like raid 5). Second, without the SoftRAID application - it may be difficult (impossible?) to implement a RAID 5 config. You can download the SoftRAID application restriction free for 30-days, this will allow you to experiment with various RAID configurations and you can decide from there..

I'll check it out. Anyway within Disk Utility to see what kind it is?

See image. No option to add to it either

With 4 disks in the member raid set and a total capacity of 16TB - you have definitely created a RAID 0 set. Every other RAID 'mode' would, by definition, report a total volume capacity of 12TB or less.

To my knowledge, you can't add new disks to a RAID 0 set.

Coming from the Windows universe and "spares", I wish I knew this in advance
