Does ElectricEel support change vdev's parity ratio for existing vdev?

TrueNAS General

My current configuration is 1 vdev, raidz1 with 4 disks. Is it possible to upgrade the pool to 1 vdev raidz2 with 6 disks?

I saw the “Extend Vdev” option in pool configurations, but the hint says it will keep the pre-extended parity ratio.

Does TrueNAS or ZFS currently support to “upgrade” parity ratio (use a more secure redundancy)? If not, is there any plans to support this on ZFS side or TrueNAS side?

no, changing the parity ratio is not currently a feature.

The Extend button as you see it, only extends the width of a VDEV of an existing type. IE a raidz1 will stay a raidz1.

Not only is changing parity ratio not currently a feature, it isn’t in the pipeline, at least in anything like the near term.
