I have 2 storage pools. One is spinning disk HDD based with log and cache vdevs. I also tried building a SSD based pool with cheap SSD’s and found performance is an issue and it’s the pool I used to configure and build several instance VM’s. I added the HDD pool to the configuration for instance VM’s but am unable to figure out how to migrate the existing VM’s disks to the HDD pool and remove the SSD pool from the configuration. Any help would be greatly appreciated. My plan is to eventually destroy the SSD pool and replace all the disks with better SSD’s that will work with ZFS. In the mean time would like to move all datasets to the HDD pool without destorying the existing datasets and data on the HDD pool.
We need details of your pool layouts. Can you please run the following commands and post the output from each in a separate </> box:
/sbin/zpool status -vLtsc lsblk,serial,smartx,smartlspcisudo sas2flash -listsudo sas3flash -listsudo storcli show all
Also, brief details of your hardware (MB, processor, memory, storage controllers) would be helpful.

@Protopia does this help?
Yes it does indeed help. (And apologies for having missed the notification that you posted the output more than 1.5 weeks ago.)
Assuming that your ashift is 12 as normal, the block size of your SSD 2x 9x RAIDZ2 pool is effectively 28KB (7 data drives + 2 parity drives in a vDev).
So every time your VM’s virtual disk reads a random 4KB block, ZFS reads 28KB. And every time your VM writes a random 4KB block, it reads 28KB to get the other 24KB and writes 28KB. This is called read and write amplification - and with this it is no wonder that you are getting terrible performance for VMs on your SSDs. This is why mirrors are recommended for virtual disks and databases.
Take your 18 SSDs and recreate the pool either as 9x 2-way mirror vDevs (or 6x 3-way mirror vDevs if you want double redundancy like RAIDZ2).
If you are not running VMs etc. on your HDDs, the mirrored SLOG is probably unnecessary - but if you decide to keep them then beware that these S841E400M2 drives do NOT have PLP.
You should also check your L2ARC stats to see if these are doing anything for your performance.
Thanks for the advice. I’ll definitely give it a try. In the meantime is there a way for me to migrate my VM disks from one pool to the other so that I can try reconfiguring it?
