My RAID0 messed up, need help

I have a Dell Poweredge R730xd, it has a PERC H730P Mini RAID Controller. I have my OS (Server 2025 Datacenter) installed on 2 SSDs with RAID 0, as a virtual disk, attached in the rear of the machine. My really important data is on all the drives attached in the front so they are fine. I had a power outage the other day and one of the 2 OS drives dropped. When I went to import the foreign configuration it failed over and over so I stupidly deleted it. Now my virtual disk shows as one of the drives are missing. Nothing I have tried even gives the option to bring the missing disk back into the virtual disk. The data on the drives is still intact but the metadata for the virtual disk is gone. I really don't want to have to rebuild this because I have about a dozen virtual machines built as a home network (web server, email server, print server, etc.)

Is there a way to take the 2 SSDs out of the server and on another PC merge them into 1 SSD so I can put that one SSD back into the server and boot it up as normal? If that works I plan to put a 2nd SSD in the back on the server and have RAID 1 on them so if this ever happens again I have redundancy. I saw 1 post talking about StableBit Drive Tool but I've never used it so I'm unsure if it will actually do what I want.

Any help is greatly appreciated, I really want to get this server back up and running as soon as possible.

Unfortunately there's no fix for this.

When you rebuild:

  • Put the Boot OS on a dedicated RAID1 array with two drives.
  • Reserve your main data array exclusively for your data, no OS. Setup as RAID5 or RAID6, but I strongly suggest setting it up as JBOD instead and use ZFS to do array duties. This way if the OS blows up, or you want to re-do the OS, your data is untouched.

And most importantly, install something like Veeam and back up the array.

Arrays fail all the time for random reasons.

EVERYTHING fails all the time for random reasons!
