[ceph-users] Update erasure code profile

Hi, We are running a Nautilus cluster and  have some old and new erasure code profiles. For example: # ceph osd erasure-code-profile get m_erasure crush-device-class=hdd crush-failure-domain=host crush-root=default jerasure-per-chunk-alignment=false k=6 m=2 plugin=jerasure technique=reed_sol_van w=8 # ceph osd erasure-code-profile get c_erasure crush-device-class= crush-failure-domain=host crush-root=default jerasure-per-chunk-alignment=false k=4 m=2 plugin=jerasure technique=reed_sol_van w=8 Here we want to add crush-device-class information to the second profile. Is the following correct? Safe? What will actually happen if we run this command? # ceph osd erasure-code-profile set c_erasure crush-device-class=hdd k=4 m=2 --force Thanks for any input!
