• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description Michael Jones 2019-07-23 21:33:06 UTC]

As you can see in the ceph-14.2.2 ebuild, the MGR_DASHBOARD_FRONTEND configuration flag is unconditionally given "NO".

ceph-14.2.2-r1 ebuild -- tries to enable dashboard

[Comment 2 Michael Jones 2019-07-25 18:19:19 UTC]

The following ebuild attempts to add the dashboard functionality.

However, because the build process when the dashboard is enabled executes node package manager, the gentoo sandbox prevents the build from finishing (as it should).

I don't know how to properly solve this, and would appreciate targeted advice.

Is this why i get 
ceph mgr module enable dashboard
Error ENOENT: module 'dashboard' reports that it cannot run on the active manager daemon: No module named 'jwt' (pass --force to force enablement)
?

[Comment 4 Patrick McLean 2021-02-25 23:49:27 UTC]

Is this still an issue with modern ceph versions? I suspect it was just a missing jwt dependency
