Bug #35917
closedmgr/dashboard: Allow the decrease of pg's of an existing pool
0%
Description
With the newest addition of Sage, it is by now possible to decrease the number of placement groups of a pool. This should also be possible using the dashboard.
ceph osd pool set {pool-name} pg_num {pg_num}
See also placement groups.

I wonder if it will actually be necessary to change these values manually via the dashboard - as far as I understand it PR#24184 implements a Manager module that automatically manages this.

As far as I understand it, the PR mentioned doesn't eliminate the need to set a PG number for creation of pools and might also not eliminate the need to be able to change the PG numbers manually.

We're offering to set the number of placement groups on pool creation and offering to increase the number of placement groups for an existing pool, but preventing the user in the UI from decreasing it again. As this should be possible by now, I tend to just remove limitation from the frontend (and maybe also the backend).

Converting this from "feature" to "bug" - not being able to change this via the dashboard while it's possible on the command line is an inconsistency we ought to fix.

Flagging this one for backporting into Nautilus as soon as the remaining comments on the PR into master have been addressed (which will be done in separate PRs)
