Subject [jira] [Commented] (COUCHDB-1652) CouchDB does not release disk space from .deleted files
Date Thu, 02 Apr 2015 09:38:54 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1652?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14392449#comment-14392449

Robert Newson commented on COUCHDB-1652:
----------------------------------------

does this ever happen without the compaction daemon enabled? I wonder if it's holding the
db open (which would be ironic...)

>          Components: Database Core
>    Affects Versions: 1.2
>         Environment: Ubuntu 8.04, 10.04, 12.04 , CouchDB 1.2.0, CouchDB 1.2.1, Erlang

> I noticed on long running servers a disk space increase over time. Though the database
in itself did not grow. After investigation i found that there are lots of files still open
which have already been deleted.
> I see this on all installations on Ubuntu 8.04, 10.04 and 12.04 all 64bit with CouchDB
1.2.0 and 1.2.1 with Erlang 14b4.

> CouchDB should release the file pointer on those files, to release the disk space to
tools like df.
