Yes, it prevents bit rot. It's why I switched to it from the standard mdraid/LVM/Ext4 setup I used before.

The instructions seem correct but there's some room for improvement.

Instead of using logical device names like this:

sudo zpool create zfspool raidz1 sda sdb sdc sdd sde -f

You want to use hardware IDs like this:

sudo zpool create zfspool raidz1 /dev/disk/by-id/ata-ST8000VN0022-2EL112_ZA2FERAP /dev/disk/by-id/wwn-0x5000cca27dc48885 ...

You can discover the mapping of your disks to their logical names like this:

ls -la /dev/disk/by-id/*

Then you also want to add these options to the command:

sudo zpool create -o ashift=12 -o autotrim=on -O acltype=posixacl -O compression=lz4 -O dnodesize=auto -O normalization=formD -O relatime=on -O xattr=sa zfspool ...

These do useful things like setting optimal block size, compression (basically free performance), a bunch of settings that make ZFS behave like a typical Linux filesystem (its defaults come from Solaris).

Your final create command should look like:

sudo zpool create  -o ashift=12 -o autotrim=on -O acltype=posixacl -O compression=lz4 -O dnodesize=auto -O normalization=formD -O relatime=on -O xattr=sa zfspool raidz1 /dev/disk/by-id/ata-ST8000VN0022-2EL112_ZA2FERAP /dev/disk/by-id/wwn-0x5000cca27dc48885 ...

You can experiment till you get your final creation command since creation/destruction is nearly instant. Don't hesitate to create/destroy multiple times till you got it right.
