From: robert Date: Tue, 31 Aug 2021 05:29:55 +0000 (+0000) Subject: add support for obtaining sense status and source slot of a media X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a3f7ec94f228796f5f182ee75acf79852c3ff805;p=openbsd add support for obtaining sense status and source slot of a media this fixes a bug in bacula where the catalog was not properly kept up-to-date if a tape was in a drive becuse its source slot was unknown based on code from FreeBSD;
