I mistakenly created a cache pool with way too few PGs. It's attached as a write-back cache to an erasure-coded pool, has data in it, etc.; cluster's using Infernalis. Normally, I can increase pg_num live, but when I try in this case I get: # ceph osd pool set cephfs_data_cache pg_num 256 Error EPERM: splits in cache pools must be followed by scrubs and leave sufficient free space to avoid overfilling. use --yes-i-really-mean-it to force. Is there something I need to do, before increasing PGs on a cache pool? Can this be (safely) done live? -- Mike Shuey _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
