I've been testing out an Intel X25-E SSD as a slog device. Functionality
wise, it works great -- performance on some of my testing approaches the
same level as completely disabling the zil.
Unfortunately, fma isn't very happy with the drive. It keeps saying the
drive has failed self test and marking it as faulty. This does not impact
functionality, the drive remains available and works fine. However, the
fault indicator light on the chassis and on the drive is lit, IPMI
management asserts a drive failure status and the logs are cluttered with
erroneous failure notifications.
I was wondering if this was a problem with the drive not supporting
whatever SMART functionality fma is looking for, or some type of
incompatibility.
Here's the fault report:

faulty
Also, it does not look like the drive includes a temperature sensor, or at
least the value is not being reported correctly:
c5t0d0p0 2600J6032HGN ATA SSDSA2SH032G1GN 8626 255 C (491 F)
If there is no way to get this drive to play happily with fma, is there any
way to disable self tests on the drive to prevent the erroneous fault and
error notifications?
Thanks...
