Martins Balodis commented on COUCHDB-1652: ------------------------------------------ I am also having the same issue with couchdb 1.5.0-0ubuntu1 (ubuntu 14.04). The CouchDB process is not releasing deleted files. I have configured compaction like this: [compaction_daemon] check_interval = 600 min_file_size = 131072 [compactions] _default = [{db_fragmentation, "70%"}, {view_fragmentation, "60%"}, {from, "00:01"}, {to, "23:59"}] "lsof | grep "/var" | grep deleted" returns something like this (all of the files look like uuid): beam 2197 couchdb 10u REG 253,1 12353800 262606 /var/lib/couchdb/.delete/73e327a88bae8d099ae6ec3e4760a3aa (deleted) beam 2197 couchdb 13u REG 253,1 22823198 262662 /var/lib/couchdb/.delete/8e12d686809f4fa13046de351bd83fb8 (deleted) beam 2197 couchdb 15u REG 253,1 7485649 262657 /var/lib/couchdb/.delete/7ae650ed196bceb36902ab93d4db949c (deleted) > CouchDB does not release disk space from .deleted files > ------------------------------------------------------- > > Key: COUCHDB-1652 > URL: https://issues.apache.org/jira/browse/COUCHDB-1652 > Project: CouchDB > Issue Type: Bug > Components: Database Core > Affects Versions: 1.2 > Environment: Ubuntu 8.04, 10.04, 12.04 , CouchDB 1.2.0, CouchDB > 1.2.1, Erlang 14b4 64bit platform > Reporter: Simon Eisenmann > Assignee: Randall Leeds > > I noticed on long running servers a disk space increase over time.
