Hi, I have been trying to run a test from qa/tasks/cephfs/test_volume_client.py but I get "RuntimeError: Fuse mount failed to populate /sys/ after 31 seconds". I am using the command "$ python2 ../qa/tasks/vstart_runner.py --interactive --create tasks.cephfs.test_volume_client.TestVolumeClient.test_default_prefix" to run the test and I've copied the output of this command here [1]. Despite of the error I can mount using ceph-fuse it manually - $ sudo mkdir /mnt/cephfs && sudo ./bin/ceph-fuse /mnt/cephfs ceph-fuse[354]: starting ceph client ceph-fuse[354]: starting fuse Could it be something with the way fuse is configured? fuse.conf contains only 2 lines - $ cat /etc/fuse.conf mount_max = 1000 user_allow_other I've tried running the test after rebuilding ceph from scratch (tried "git clean -fdx" as well as getting a fresh copy of the ceph repo) and creating the virtual environment required for running tests again. I am using CentOS-7-x86_64-GenericCloud-1708 as my OS. The setup is odd indeed but vstart cluster as well as tests have worked fine before.
