  3. Proxmox on ZFS - Should I be worried ?

    Hi, I self-host Proxmox on a dedicated server, running on 2 SSDs in ZFS mirror + 2 hard drive with independant pool. My SMART results on the SSDs start to worry me a bit, and I'm thinking about ditching ZFS. Some recap: It seems to me the "Power_On_Hours" is incorrect. This server has...
