Comment 2 Ken Dreyer (Red Hat) 2017-08-08 17:21:52 UTC

/usr/bin/fusermount is in the "fuse" RPM package. Looks like ceph-fuse depends on "fuse-libs", not "fuse".

I wonder if the docs should be updated to tell users to mount with "mount" rather than "fusermount"? That's what mounting via /etc/fstab does, right?

Comment 3 Patrick Donnelly 2017-08-08 17:53:29 UTC

Docs in question: https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/2/html/ceph_file_system_guide_technology_preview/mounting_and_unmounting_ceph_file_systems#unmounting_ceph_file_systems

simple `umount` gets a EPERM on my system while `fusermount -u` works. I believe we will need to add the fuse dependency.

Comment 4 Ken Dreyer (Red Hat) 2017-08-08 17:56:00 UTC

Rachana can you please verify "yum install fuse" allows you to proceed?

Comment 5 Ramakrishnan Periyasamy 2017-08-11 06:12:47 UTC

"yum install fuse" works but it picks package from RHEL repo, after installation "fusermount" utility available.

Comment 6 Patrick Donnelly 2017-08-21 16:54:09 UTC

Ken, how should we proceed on fixing the package dependencies?

Comment 7 Ken Dreyer (Red Hat) 2017-08-21 19:07:51 UTC

I've reviewed the Debian packaging and this has been implemented since the very beginning. We just missed the "Requires: fuse" on the RPM side.

https://github.com/ceph/ceph/pull/17120 adds it.

Comment 11 Ramakrishnan Periyasamy 2017-08-30 05:13:54 UTC

Moving this bug to verified state.

fusermount mount utility available part of ceph-fuse package.

Verified in build: 12.2.0-1.el7cp (b661348f156f148d764b998b65b90451f096cb27) luminous (rc)
