  3. [SOLVED] Samsung SM883/PM883 SATA SSDs for ZFS RAID1?

    So far I've read the Samsung SM883 would be great in general. Would that be so? There are also PM883s and cost 50% compared to the SM883. Are they both do their job, without queuing a regular (VM) Windows 10 update for example? I've been using 2 PNY CS900 and they hit the limit pretty fast...

    I have Home Assistant and Ubuntu 20.04 running in virtual machines and every day I come home to find the console flooded with these messages. I ran a SMART test on my SSD and it came back clean with no errors. Sometimes when I reboot the VM it starts back up fine, other times I have to run fsck...
  13. 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...

I have two PVE 7.0 on ZFS, one with 12 x 4TB 7.2K SAS HDD in ZFS RAID 10, the other with 4 x 4TB SATA SSD in Z1 and they're coming out with near identical IO performance, which is suspicious! From benchmarking with FIO with caches and buffers disabled, on sequential read / writes, the...
