Spares are just pool drives.
Cache can be shared (SAS) or independent (one per host).
Logs need to be shared SAS disks.
I can look into updating this...
I understand this from other isssue here. I mean there is no instructions how to set them up. Just result. Also. What about using vdev_id.conf aliases? Is it acceptable?
What do you need help with?
Is it acceptable to use /dev/disk/by-vdev/ names to create HA pool and in pcs? /dev/disk/by-vdev/ names generated based on vdev_id.conf https://github.com/zfsonlinux/zfs/wiki/FAQ#selecting-dev-names-when-creating-a-pool As I understand conf should be same on both head nodes.
I'd recommend /dev/mapper multipath devices for zpool creation.
You describe hardware, but there is no description how to set them.
BOOM! cache spares logs what? where? how? Could it be added later? Should it be shared or hostbased?
