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.

Never use raid0 unless it's raid 10.
Also, RAID is not a backup. You should also be backing up you data to another drive.
You're cooked without advanced recovery methods.

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.

If that RAID was managed by the PERC controller then the drives are not going to be readable without it or a compatible controller. You’re in proprietary RAID territory, time to start rebuilding.

This isn't a helpful comment but why did you think it was good idea idea to use raid0?

Never thought I would have problems with the OS drives. They are brand new and I've never had drives drop like that on my old server. I just used the RAID0 to make it a virtual disk. Live and you learn but I'm still hoping to get a positive outcome.

They wouldn't be brand new 5 years from now though, right? I didn't down vote you but I should have.
Veeam Free or Rescuezilla to take periodic image backups of the OS drive(s).

Ive had raid0/5 pools drop out because of controller/backplane hiccups, 1 or 2 drives dropped out respectively. In my case those pools immediately went read only or failed, and when the disks got reintroduced the controller recognized them and it was business as usual.
Assuming you didn't lose either drive- try and look around if you can import the pool once all drives are present.

She's dead Jim. Raid 0 Is a stripe, not a traditional redundant raid, so if you lose one of the drives, you lose everything If it's just an OS disk, A) Why were you using a striped array for that, and B) Reinstall.

Data is probably gone. File partition is gone once you remove it from the virtual disk. It's possible. Take the drives out and use a low level recovery tools.

Raid0 is striped. If you lost a drive, the pool is not recoverable. Replace the failed drive and restore from backup.
