Is really true that ZFS has detected that a device was removed?

I have an email from NAS saying the above BUT the web UI say that all disks are good

Plus the disks are red on the frontpanel …

I will try to attach a picture of the UI

so… any guess on what is happening ?

Apparently I cannot embed images on a post

is there any way to send a screenshot of the web UI ?

Try it now I’ve increased your trust level.

Could you share the output of zpool status along with your hardware specs please.

It’s strange the capacity isn’t being populated for every disk. The screenshot looks similar to the other person that is having trouble with a new HBA and a Norco case.

Any info on the system?

Hopefully nothing “private” is shared

Does the email provide more information, eg what device?
