Hi Ken, I have been talking with the illumos guys about the shell problem. They all agreed that ksh (and specially the ksh93 used in illumos) is absolutely Bourne-compatible, and that the "local" variables used in the ocf shells is not a Bourne syntax, but probably a bash specific. This means that pointing the scripts to "#!/bin/sh" is portable as long as the scripts are really Bourne-shell only syntax, as any Unix variant may link whatever Bourne-shell they like. In this case, it should point to "#!/bin/bash" or whatever shell the script was written for. Also, in this case, the starting point is not the ocf-* script, but the original RA (IPaddr, but almost all of them). What about making the code base of RA and ocf-* portable? It may be just by changing them to point to bash, or with some kind of configure modifier to be able to specify the shell to use. Meanwhile, changing the scripts by hands into #!/bin/bash worked like a charm, and I will start patching.

The RAs typically start with #!/bin/sh, so whatever that points to on your system is what will be used. I also tried modifiying all ocf shells with "#!/usr/bin/bash" at the beginning, no way, same output. You'd have to change the RA that includes them. Any idea how can I change the used shell to support "local" variables? You can either edit the #!/bin/sh line at the top of each RA, or figure out how to point /bin/sh to a Bourne-compatible shell. ksh isn't Bourne-compatible, so I'd expect lots of #!/bin/sh scripts to fail with it as the default shell.

Now looks like it's looking for "/usr/bin/gawk", and that is actually there! Is there any known incompatibility with the mixed heartbeat ocf ? Should I use corosync specific ocf files or something else? "heartbeat" in this case is just an OCF provider name, and has nothing to do with the heartbeat messaging layer, other than having its origin in the same project. There actually has been a recent proposal to rename the provider to "clusterlabs" to better reflect the current reality. The "couldn't find command" message comes from the ocf-binaries shell functions. If you look at have_binary() there, it uses sed and which, and I'm guessing that fails on your OS somehow. You may need to patch it. Thanks again!
