Hello,

TLDR: If you're running shared storage for your VM and LXC disks off of TrueNAS Core, how are you customizing your datasets compared to the default settings? I'm aware of the need to tune volblocksize and recordsize appropriately, and will disable sync writes*. Anything else to be mindful of?*

I'm experimenting with shared storage for the first time. I've set up an all SATA SSD pool in TrueNAS Core, with two mirror VDEVs, and disabled sync writes.

Aside from making sure recordsize and volblocksize are set appropriately for my VMs and LXCs, is there any customization I need to do to the dataset properties? I've not compared the values set by Proxmox in its local datasets to the values set by TrueNAS Core when a dataset is created, but Proxmox is Linux and TrueNAS Core is BSD, so I wasn't sure if they were directly comparable or if I needed to do something to avoid having a bad time.

Thanks for any advice.
