Re: Error while installing ceph

[pavana bhat <pavanakrishnabhat@xxxxxxxxx>]

Hi Travis,

I referred the same http://docs.ceph.com/docs/master/ -> But when I hover down the page I get "latest " "development" "firefly" "dumpling". I clicked on to the "latest" then got the page i referred! Can you please let me know which one to refer?

Thanks,

A couple of things here...

Looks like you are on RHEL. If you are on RHEL, but *not* trying to install RHCS (Red Hat Ceph Storage), a few extra flags are required.  You must use "--release".  For example, "ceph-deploy install --release hammer ...." in order to get the Hammer upstream release.

The docs need to make this more clear (I don't think it's mentioned anywhere -- upstream Ceph on RHEL is not a very common case, but it is supposed to work. :))

That will at least install the right packages.  however, there is still one more issue you will hit, which is that when installing upstream Ceph on RHEL, it knows that it needs EPEL (EPEL is not needed with RHCS), and it will try to install it by name "yum install epel-release".  But that doesn't work on RHEL.  Until that is fixed, you will also have to install EPEL by hand on your nodes.

Perhaps the --repo and/or --release flags are required?

These are pretty old docs (see the version number in the URL).  It's probably always best to start at http://docs.ceph.com/docs/master instead.  How did you get to this old version?  If it was from a link, we would want to check that that link still made sense.
