Cannot add L2ARC or SLOG in Truenas Scale 21.04 from storage menu.

Description

Testbed is as follows and has just been put together:

HPE ML30 Gen10
CPU: Intel(R) Xeon(R) CPU E-2224
MEM: 64GB (2x32GB ECC)
OS Drive: 1x Intel® Optane 800p 118Gb
Storage: 4x 10TB WD Gold (2x Mirrors)
Storage: 1x Intel® P4600 1.6TB
L2ARC: 1x Intel® Optane 900p 280GB
HBA: 1x 9400-8i
NET: HPE Mellanox CX5 25GbE, 2 ports (10GB fibre link, 25GbE DAC to workstation)

I've successfully imported my old pool (4x 10TB) and have set the P4600 as a separate pool which will be used for vm's and general scratch disk. I have a single Intel® Optane 900p 280GB that I would like to use as a persistent L2ARC, however can't add it as a L2ARC in the interface under storage. I select add cache or log and then move the disk to either of them but the "create" button is still greyed out.

Good Morning

I will close this bug ticket since you found the solution but would you mind putting in a suggestion ticket for making the UI point of view clearer when creating the L2ARC?

Hi Bonnie,

My mistake I tried to create the L2ARC from the create button at the top of storage. Using the configure button of the pool and adding another vdev => cache allows the addition of the device to the pool. From a UI point of view maybe could be cleaner? I’ll add a debug file later this evening if needed.

Thank you for the report, .

Can you please attach a debug file to this ticket? To generate a debug file on TrueNAS CORE, log in to the TrueNAS web interface, go to System > Advanced, then click Save Debug and wait for the file to download to your local system. In TrueNAS SCALE, this option is in System Settings > Advanced.
