Hi Budai,
I agree with Nathan, just switch the crush rule. I've recently done
this on one of our clusters.
Create a new crush rule the same as your old one except with different
failure domain.
Then use: ceph osd pool set {pool_name} crush_rule {new_rule_name}
Very easy.
This may kick off some backfill so I'd suggest setting norebalance
before doing this.Rich On Wed, 8 Sept 2021 at 07:51, Nathan Fish <lordci...@gmail.com> wrote: > > I believe you would create a new rule and switch? > > On Tue, Sep 7, 2021 at 3:46 PM Budai Laszlo <laszlo.bu...@gmail.com> wrote: > > > > Dear all, > > > > is there a way to change the failure domain of a CRUSH rule using the CLI? > > > > I know I can do that by editing the crush map.
