Accidentally deleted the RAID configuration

Tuvshinjargal — Tue, 08 Mar 2022 07:42:23 GMT

Hello,

I accidentally deleted the RAID5 configuration from the controller. The controller is P420i. After that, I also recreated a logical volume from ACU. As I read from another forum, the raid configuration can be restored by configuring the exact configuration before it had. But it didn't work. Is there any possible way to restore the deleted RAID configuration?

Hello,

Once the configuration has been deleted, it can only be re-configured, but the data will be lost. Please restore from backup.

Regards,

Actually I was in a similar situation a few days ago. However, after recreating the array configuration exactly the same way as it was before (RAID 1), I was able to repair the "corrupted GPT" with gdisk (Linux) and after that, all data was available again without any damages. Fortunately.
