I run a zpool of 4x4TB nvme.

I'm not happy with sync=auto and ashift=12, 

 

I can use the cli to manually create a pool with the options I want.  HOW do I 'import' it into the GUI? If I create a pool there, it'll reformat with defaults of ashift=12 etc.

 

Is it possible?

Sync option can be changed at any time, ashift only during pool creation.

 

To import a manually created pool, you just need to assign all the pool devices, leave the fs set to "auto", and then start the array (pool must be exported).

 

 

I may be doing steps wrong, here's what I'm doing:

sudo zpool create -o ashift=13 -O sync=disabled -O recordsize=1M mypool raidz /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1

 

Then in GUI I create 4 disk pool with fs=auto. upon array startup, it keeps saying: unmountable: unsupported or no filesystem. Should I be formatting the zpool or anything else manually before I drop into gui?

 

I also tried the following after manual pool creation before setting in gui:

 

sudo zfs set aclmode=passthrough speedteam

sudo zfs set aclinherit=passthrough speedteam

sudo chmod -R 777 /speedteam

sudo zfs set mountpoint=/speedteam speedteam

type

zpool export speedteam

then restart the array, and if it still doesn't mount, post the diagnostics.
