hello thanks for the support thread, currently I have a cluster with 3 nodes I use powerdell r630 equipment with raid 1 for the hypervisor part with 2 ssd disks and with raid 5 for the MV part with 3 ssds, from time to time I get tables It happens that one of the raid 1 disks where the hypervisor is located is corrupted. I use Western Digital Sa500 drives. Can you tell me if it is a compatibility problem with the SSD drives or because of the raid configuration, what would be the best configuration to avoid data loss? data, also indicate that I use a proxmox backup to make copies of the MV every 2 days, thanks and regards.
