> Every failing hard drive requires a stressful operation on the remaining disks (resilvering) that may push the next drive to failure.
I saw something similar: RAID array with 5 disks and 3 spare disks.
One night controller detected failure, ejected one drive and replaced with spare.
After rebuild of RAID it ejected another disk and then another. In an hour all spare disks were used and on fourth failure it stopped work
Fascination in combination of interesting tools with very interesting tools in a very very unconventional workflow.
I like it.
I'm certain that I will not use the same workflow but it gave me ideas for my own.
