Hi, I have a server running a 6TB pool on an HP-P420 hardware managed raid 50 (seen as a single device by the system). This card has a battery backed hardware cache. What is the correct value of the zfs:zfs_nocacheflush in this case, to be totally safe? I have always been confused by this flag... Also, the gen8 HP system is giving these warnings on boot, maybe I should take care of them? 1.
