Description of problem:
Ceph is a software-defined storage project, and it stores its data in /var/lib/ceph as a big set of files. The problem is that updatedb indexes /var/lib/ceph along with everything else on the system. This /var/lib/ceph location is typically *very* large, and Ceph users are not supposed to go poking around at the files in there.

Version-Release number of selected component (if applicable):
mlocate-0.26-9.fc22

How reproducible:
always

Steps to Reproduce:
1. mount some large OSD disks under /var/lib/ceph
2. updatedb runs and indexes all of the OSDs' files

Actual results:
IO slows to a crawl

Expected results:
updatedb excludes Ceph data (add /var/lib/ceph to PRUNEPATHS)

Additional info:
Ceph also has a filesystem, so it would be nice to exclude the "ceph" and "fuse.ceph" filesystem types as well (via PRUNEFS).

For more background information, see a thread on the ceph-users mailing

Thanks for shipping this change!

Would you mind excluding the "ceph" and "fuse.ceph" filesystem types as
well, adding them to PRUNEFS?

Title:
  updatedb.conf: CephFS should be included in PRUNEFS

Status in mlocate package in Ubuntu:
  Confirmed
Status in mlocate package in Debian:
  Fix Released
Status in mlocate package in Fedora:
  Fix Released

Bug description:
  CephFS filesystems can become huge. It's networking filesystem for a
  client and clients should not index data on CephFS filesystems.

  I suggest that "ceph" and "fuse.ceph" is added to "PRUNEFS" in
  /etc/updatedb.conf to prevent all the clients to start indexing this
  network filesystem.
