Hi all,
I need some help yet again... With my cluster backup and running Ceph 10.2.3, I am having problems again mounting an RBD image under Xenserver. I had this working before I broke everything and started over (previously on Ceph 10.1), I made sure to set tunables to legacy and disabled chooseleaf_vary_r which is how I got it working before. Now when I try to manually mount the image:
echo "192.168.10.39,192.168.10.40,192.168.10.41 name=admin,secret=secret xen vm0" > /sys/bus/rbd/add
It fails with:
echo: write error: No such device or address
This is different that when I was having problems before getting this working, something must have changed in 10.2? Below are more details, I hope it helps.
Here is the trace output:
