This is a pool consisting of two single disk vdevs, so you cannot remove a disk without destroying the pool. P.S. Next time please enter the command zpool status as asked and copy & paste the resulting text output into a "code" block. Thanks!
FreeNAS/TrueNAS ZFS NVMe SSD Pool with multiple datasets. ... dataset, or zvol, will tell the client application that all writes has been complete and committed to disk (HD or SSD) before it has actually done so. This allows the system to cache writes in the system memory. In the event of a power loss, crash, or freeze, this data will be lost ...
Unfortunately, I suspect that you will need to backup your entire pool, then destroy the pool, re-create it, and restore from backup. In general, it is not possible to remove VDEVs from a ZFS pool without destroying the pool and re-creating it.
I had to detach the faulty drive to be able to boot the server up again. To replace the disk you must have a replacement disk from the same size or bigger. Because I have to upgrade my pool to a bigger capacity I will change all my 2TB drives to 6TB drives but for obvious reasons I will begin with the bad one: ``I like my data``.

They constantly state all I can do to increase my 6 x 4TB RAIDZ2 pool is to create a new vdev of say, mirrored disks. Is it yet possible to put in two more 4TB HDD's and just add them into an existing raidz2 without data loss? I have two free bays and need to expand. Running TrueNAS-12.-U1 on a Dell R510. Thanks!
The root pool is too small and you want to replace a smaller disk with a larger disk. A root pool disk is failing. In a non-redundant pool, if the disk is failing such that the system won't boot, you must boot from an alternate media, such as a CD or the network, before you replace the root pool disk.
After your last disk is added and the pool has been resilvered you should see a nice new message on the Pools status page or on ssh that your pool is larger than before. Conclusion My ZFS pool in FreeNAS increased in size automatically from ~15TB to ~65TB following the steps above. Make sure to do a single disk at a time and your pool is ...
