  • I use zfs with Proxmox. I have it as a bind mount to Turnkey Fileserver (a default lxc template).

    I access everything through NFS (via turnkey Fileserver). Even other VMs just get the NFS added to the fstab file. File transfers happen extremely fast VM to VM, even though it’s “network” storage.

    This gives me the benefits of zfs, and NFS handles the “what if’s”, like what if two VMs access the same file at the same time. I don’t know exactly what NFS does in that case, but I haven’t run into any problems in the past 5+ years.

    Another thing that comes to mind is you should make turnkey Fileserver a privileged container, so that file ownership is done through the default user (1000 if I remember correctly). Unprivileged uses wonky UIDs which requires some magic config which you can find in the docs. It works either way, but I chose the privileged route. Others will have different opinions.








  • There are two types, CMR and SMR. You can read online about the differences. CMR is better because SMR tries to be all fancy in order to increase capacity, but at the cost of speed and data integrity.

    It won’t be front and center in the specs of a particular drive, but you usually find the info somewhere.

    I wouldn’t worry about higher capacity failing sooner. If you have 10x4TB vs 2x20TB, that’s 5x as many drives to go bad. So a 20TB drive would need a 5x worse fail rate to be considered worse. A pro of larger (fewer) drives is lower power consumption. 5-10 watts per drive doesn’t sound like much, but it adds up.
