All,
I have a test environment with 4 internal disks and RAIDZ option.
Q) How do I simulate a sudden 1-disk failure to validate that zfs / raidz
handles things well without data errors
Options considered
1. suddenly pulling a disk out
2. using zpool offline
I think both these have issues in simulating a sudden failure
What is more sudden than yanking a live disk out when the system is
under load? Maybe cut the non-wall end off a 120V power code, and
touch the exposed wiring to your drive's circuit board?
(don't try this at home without a good fire suppression system and eye
protection)
If you're really looking to shave a few milliseconds off the time to
fail, maybe build a digital toggle switch of some kind that will short
the Tx+/- pair inside your sata data cable?
