Hard Drives split on install

[popoche28]

Hi everyone,

I install some PVE servers with this configuration
2 SSD on RAID1 for PVE OS and some storage for the VM OS disks
3 HDD on RAID5 for data disks

Everytime I install PVE on the first RAID storage (I see the right size of my RAID1 storage), when the installation is finished I have two storage like that :




The 1.6TB storage on sdb is ok when I add manualy the storage. It concerns just the sda storage.

What is the problem? why those two storages are systematly created ?

Thanks in advanced

Regards,
