I added new nodes in my DSE cluster and these are not reporting any storage capacity whereas :

  • Nodes are up and running without any problems
  • I can see them in the ring in Ops Center

This only happens on new installed nodes with the same version of DSE but with a minor difference on the ubuntu version : new servers run on Ubuntu 14.04.4 LTS and "old" servers run on Ubuntu 14.04.3 LTS.

iosta is installed on all of our servers.

Thanks

This seems to be related to:

OpsCenter does not show available storage

In summary, /proc/mounts seems to output root partition pointing to a symlink that in turn points to the actual node/partition location.

Thus, df outputs different locations (a sym link and a file) on two different df use cases: df -H and df <file>. One by node or label, and one by-uuid.

14.04.4 LTS (and 14.04.4) might be based on Debian Wheezy, which in turn had this bug reported (also related):

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=653073

Which is related to the same issue.

Please advise if your df (and /proc/mounts) output shows this behavior or if it seems to be a different case.

If this is your case, we'll get this fixed for next OpsCenter version. In the meantime, you might want to run the fix described here:

    Thanks for the answer. Indeed we have the bug you describe. We will wait for the next OpsCenter version. – vespasien Apr 15 '16 at 16:19
