             Summary: prepare_all_disks doesn't mount ephemeral devices on some nodes
                 Key: WHIRR-644
                 URL: https://issues.apache.org/jira/browse/WHIRR-644
             Project: Whirr
          Issue Type: Bug
          Components: service/hadoop
            Reporter: Karel Vervaeke


Relates to jclouds issue 1073:
http://code.google.com/p/jclouds/issues/detail?id=1073

If the used image doesn't have /dev/sd[abcde], but only has /dev/xvd[abcde], the ephemeral devices are not mounted by prepare_all_disks

As a quick hack we could check for automatically create a symlink /dev/sdX -> /dev/xvdX each time we encounter a non-existent /dev/sdX.

As a side-note: there are two scripts, prepare_all_disk.sh and prepare_disks.sh. I believe the latter is completely unused.
