> Has it worked before or did it just stop working at some point? What's the exact command that fails (and error message if there is)?
It was working using the NFS gateway, I never tried with the Ceph FUSE mount. The command is ceph-fuse --id migration /mnt/repo. No error message, it just hangs.

> Either that or reduce the number of PGs. If you had only a few pools I'd suggest to leave it to the autoscaler, but not for 13 pools. You can paste 'ceph osd df' and 'ceph osd pool ls detail' if you need more input for that.
I already have the autoscaler enabled. Here is the output you asked for
