Ubuntu 12.04 has several kernel users can choose from, some with DRBD 8.3 and others with 8.4.
To address this, they have just deployed the drbd utils v8.4.3 with "--with-legacy_utils".
This works fine for drbdadm but drbdsetup seems to not revert to the legacy version, even though drbdsetup is built and deployed to /lib/drbd/drbdsetup-83:
    # /sbin/drbdsetup show 1
    Could not connect to 'drbd' generic netlink family

    # /lib/drbd/drbdsetup-83 show 1
    disk {
        size                0s _is_default; # bytes
    ...
    }

From my (quick) reading of the source code, drbdadmin works because it adds /lib/drbd to the path using add_lib_drbd_to_path(), and drbdsetup seems not to.
Is the correct fix to add a symlink from /lib/drbd/drbdsetup-83 to /sbin, or should drbdsetup be patched to search in /lib/drbd too?

Thanks in advance,
Lionel Sausin.

"Correct" is whatever works for you. As long as you know what version you are using, use the matching tools. Note that using explicit path (anything with a '/' in it) on drbdadm or drbdsetup causes them to expect the respective "legacy" binary at that same path, beneath the current executable. (on purpose). So if you want to say /sbin/drbdsetup, and expect that to be able to execvp drbdsetup-83, then yes, you have to make that accesible under /sbin/drbdsetup-83, adding it to the PATH will not be good enough. Also, as a heads up, we are in the process on splitting out the DRBD userland, providing the "grand unified drbd utils", so this will all change again within the next few weeks/month. --=20 : Lars Ellenberg : LINBIT | Your Way to High Availability : DRBD/HA support and consulting http://www.linbit.com DRBD=AE and LINBIT=AE are registered trademarks of LINBIT, Austria.
