A curse on all those who generate JSON data with subfielded keys.
...I'm looking at you Dell PERC, with all your "Drive /c0/e32/s9 - Detailed Information" nonsense. - I KNOW what the device attachment is (I GAVE you that on the command line), what I want is CONSISTENT key names I can use JQ to filter on (This key should be "Drive Detailed Information" - or something even LESS of a mouthful).

PSA: Dell PERC H730 and ZFS
Today I learned that you CANNOT do a direct drive-swap upgrade from a Dell R720 to a Dell-EMC R740 if you use ZFS. Any PERC RAID volumes that you have will Just Work; the new PERC controller (H730 or H740) will just import the volumes and carry on as though nothing had happened. But the Perc H730P in your new R740 will destroy your ZFS volumes, because it writes all over drives it considers potentially RAIDable, which by default is ALL drives, without asking permission first and you cannot tell it that a drive is non-RAID without installing the drive first, so by the time you can tell it the drive is to be non-RAID, the damage is already done.
It will not tell you that it is doing this.
This is a HUGE step backward in ZFS compatibility from the R720 and its PERC H310.

CW: The Alarming Rise in Parkinson’s Disease with Dr. Ray Dorsey
Interview of Ray Dorsey by David Perlmutter on environmental risk factors for PD
https://youtu.be/nfsZOmSYJooThough I'm a bit skeptical overall of Perlmutter's 'Grain Brain' hypothesis, I found the video quite informative. Perlmutter asked Dorsey some insightful questions and gained a few credibility points from me for mentioning chlorogenic acid as an active constituent of coffee.

Eingige interessante Details zum Versagen von #Raid-Systemen hinsichtlich der #Integrität gelieferter Datten:
https://yewtu.be/watch?v=l55GfAwa8RI
Nicht nur das altbekannte #Raid5-#Writehole ist ein Problem, auch der Wegfall der 8 Byte Checksumme, die an den klassischen 512 Byte Sektoren dranhing (bei Laufwerken mit 520 Byte Sektorgröße). Auch dass Hardware-Raidcontroller schlicht lügen, erwähnt das Video mehrfach.
Etliche Details waren mir nicht wirklich bewusst. #PERC werden aber _nicht_ erwähnt.
