All drives are connected to the RAID controller:
2 of the as RAID 1 for the OS (Proxmox)
4 of them as RAID 10 for Storage (for all virtual machines and containers)
2 of them as RAID 1 for testing purposes as "SSD cache"
4 of them as RAID 5 + 1 as hotspare for testing purposes as "fast storage" - all SSDs
4 of them as RAID 5 + 1 as Hotspare for testing purposes as "slow storage" - spinning rust 😉
maybe more to come in the future ... 🙂
Everything which is for testing purposes is directly mounted to the VM (Proxmox does see this virtual disks but is not using it)
If I don't configure them in the RAID controller (ether as RAID or as standalone) I am not able to do anything with them - Proxmox does not see them, they don't appear anywhere, like there would be nothing- so I need to configure all my physical drives first to create virtual drives to do anything with them 😄 This is the main reason I am "complaining" about HexOS asking for more drives to create a pool - all redundancy is covered by the RAID controller - no need for HexOS or TrueNAS to create any kind of pool with multiple disks ... There are some free SATA ports on my MB, but to be honest, I don't really want to connect the storage there
Due to the fact everything important is running (not yet virtualized) there no rush for me, so I will patiently wait for the upcoming release of Hex.
Thanks guys for all the tips and comments on that! This is really very much appreciated, talking to guys like you
