Subject [jira] [Commented] (COUCHDB-1667) Gracefully update from view_index_dir to index_dir
Date Tue, 05 Feb 2013 18:04:12 GMT


Jan Lehnardt commented on COUCHDB-1667:


For the record, I too like the new wording, but I don’t think it is worth adding error prone
code to cope for it at this point :)

>            Priority: Blocker

> CouchDB 1.3 ships with new couch_index app[1] that uses `index_dir` config option to
locate directory to store view indexes. However, it replaces[2] old `view_index_dir`option
creating situation when recently updated default.ini will have only `index_dir` option and
old, but production used local.ini would still have `view_index_dir`. There is a fallback[3],
but there no insurance that it will let user gracefully update.
> This situation may leads to very bad situations, when all indexes will be rebuilded against
location that may not expects their on disk size (since `view_index_dir` was pointed to the
another mount point) which leads to server fall.
