Custom Configuration:Advanced users can manually partition larger drives to create equal-sizedRAID partitionsthat match the smaller drives, and then use these partitions to create a more balanced RAID setup. Best Practices for RAID 1 with Different Size Drives in ZFS ...
For optimal performance, the pool sector size should be greater than or equal to the sector size of the underlying disks. Since the property cannot be changed after pool creation, if in a given pool, you ever want to use drives that report 4KiB sectors, you must set ashift=12 at pool ...
ZFS requires one or more dedicated block devices, preferably solid-state drives (SSDs). The /var/lib/docker/ directory must be mounted on a ZFS-formatted filesystem. Changing the storage driver makes any containers you have already created inaccessible on the local system. Use docker save to ...
Despite being new to FreeNAS, over the past few months of use I have really come to appreciate how powerful it is as a storage operating system (in particular ZFS with adequate RAM!). Drive Setup: 6x WD Red 3TB in Raid-Z2 (Half the drives have the 80.00 firmware, the others have ...
into zpools, made up of one or more virtual devices, referred to as vdevs, and manages all the devices as a single entity. A user can add more storage drives to the pool when the file system needs additional capacity. ZFS is highly scalable and supports a large maximum file size. ...
3 different drives showing the same errors at more or less the same points in the resilvering process is pretty damning. I strongly suggest that people DO NOT attempt to replicate my attempts to force a drive into the array to see what happens next. I'm still cleaning up the mess. ZFS...

RAIDZ Combines disk drives and data storage devices into a single virtual storage device. RAIDZ can use either single (Z1), dual (Z2), or triple (Z3) parity for data protection. If a drive fails, the data can be rebuilt (“resilvered”) to a spare drive to prevent data loss. ...
ZFS has a number of neat tricks for managing numerous drives. Because all disk is thrown into a single pool, adding drives to existing arrays is instantaneous, and it requires no re-initialization. During quiescent periods, ZFS will reallocate the data across all disks for better performance, ...
works. It can be mitigated with bigger volblocksize and using more disks in the RAIDz, but IMHO isn't worth it: just buy more/bigger drives and stick to RAID10, specially when the total space needed will be low and you are using consumer drives, as using more/bigger drives is cheap...
