Hi,
I work with Maggie, and had a follow up question about running multiple
instances of couchdb using one binaries directory. When setting up a cluster,
I understand I need to set the identity of each node in vm.args. I tried the
following to have couchdb look in a different location for the vm.args file:
export ERL_FLAGS="-couch_ini /myinstance1/default.ini
/myinstance1/local.ini -args_file /myinstance1/vm.args"
However, the couchdb log shows the node identity as: nonode@nohost
Then I tried specifying -name in ERL_FLAGS:
export ERL_FLAGS="-couch_ini /myinstance1/default.ini
/myinstance1/local.ini -name [email protected]"
And I still get: nonode@nohost
Finally, I tried specifying -sname in ERL_FLAGS, and this seems to work, but
gives a shortname:
export ERL_FLAGS="-couch_ini /myinstance1/default.ini
/myinstance1/local.ini -sname myinstance1"
And now I get: myinstance1@hostname1. Is there any way I can either point
couchdb at my instance's vm.args file, or I can specify the fully qualified
-name option correctly?
Thanks for your help!

Thanks Adam and Jan. We were able to have a few instances running with the
workaround.

Thanks Jan, that was a bit cleaner than I realized. It’s a decent workaround.
Important to note that every file you want to be consulted needs to be listed
there — the couch_ini flag will override the default search space entirely.
