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.
