    Yes. you should be able to flash it with an LSI 9211-8i IT firmware, to fully present the disks to the system (which ZFS prefers). With that said, that hba should be able to give you an additional 8 SATA/SAS hdds via 2x breakout cables, or even more via expanders.

    Apologies, I mean 2 file systems on one pool which resides on one vdev.

    Meanwhile, the damn 8TB drives are stuck in customs.

    hey Gea,

    When you did your testing on optane as an slog, were you able to do any comparative testing on the different scsi drivers on esxi (lsi sas, pvscsi, nvme)?

    The new OmniOS is the first Open-ZFS storage distribution to include the vdev remove (Pool shrink).
    Oracle Solaris 11.4 also comes with this feature but it seems with less restrictions.

    Open-ZFS, at least currently lacks the support for a vdev remove of a basic or mirror vdev when a raid-z [1-3] vdev is part of the pool or a remove raid-Z[1-3] at all or add a raid-z [1-3] after a remove of ex a basic/mirror vdev what limits its use cases. Support of raid-Z [2-3] is expected in Open-ZFS (but not Z1), Bug #7614: zfs device evacuation/removal - illumos gate - illumos.org

    Open-ZFS ex OmniOS that is the first to include this feature also requires a re-mapping table with a continous small RAM need/reservation and small performance degration.This is listed in the output of a zpool status. A manual zpool remap can fix this.

    It seems that Solaris 11.4 does not have these restrictions
