Hi, I've tried setting all values the same as the current layout - changing only the pool number and I still get; root@dsan-test:/mnt/ceph-test# cephfs /mnt/ceph-backup show_layout layout.data_pool: 0 layout.object_size: 4194304 layout.stripe_unit: 4194304 layout.stripe_count: 1 root@dsan-test:/mnt/ceph-test# root@dsan-test:/mnt/ceph-test# cephfs /mnt/ceph-backup set_layout -p 3 -s 4194304 -u 4194304 -c 1 Error setting layout: Invalid argument If I leave all values exactly the same i.e '-p 0' the command runs without any error output. However, changing the pool from anything but 0 results in 'Error setting layout: Invalid argument' Any ideas? Grant
