Said about mergerfs as an alternative
Alexey Skobkin
It does the same thing as mergerfs but with better flexibility and more features. It also more stable.
Comments and Reviews
It's good for merging several filesystems from different disks without using LVM or RAID. Moved from mhddfs to mergerfs because of frequent segfaults.
