Dear All,
I would like to add SSDs to an existing NAS to benefit from a fusion pool for future writes. My current HDDs are four drives in RAIDZ1.
The doc article says:
"The redundancy of this device must match the redundancy of the other normal devices in the pool."
and
"When adding disks to the pool, select the number of hard disks desired to be in the VDEV and ensure the pool is set to Mirrored."
I am somewhat confused here. My ideal would be to add three NVMe SSDs in RAIDZ1. Would this be possible and advisable? The first statement: "match ... redundancy" might sound like: Needs to be four NVMe SSDs in RAIDZ1, like the HDDs. The second statement: "ensure ... mirrored" might sound like: Needs to be two NVMe SSDs.
Regards,
Michael
