Question, using this on a vanilla kernel (Unraid 6.9.2, Linux NAS01 5.10.28-Unraid #1 SMP Wed Apr 7 08:23:18 PDT 2021 x86_64 Intel(R) Xeon(R) CPU E5-2420 0 @ 1.90GHz GenuineIntel GNU/Linux) works fine, however Persistent Reservations (SCSI-3) isn't working correctly, as I'm trying to do some fancy failover cluster stuff.
I'm getting "Failed", and "The device is not ready", with an error of 0x80070015. After doing some searching of Windows errorness, some people mention its because Persistent Reservations wasn't working with LIO (3 years ago, but might be a clue?).
Is it because I'm missing the custom kernel?
