Subject: Added possibility to automatically migrate RRD files from v3 to v4.
X-Git-Tag: collectd-4.0.2-1~64
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=fa6349ff50c3be59891d166cd51c0d4cf2e0ce92;p=pkg-collectd.git

Added possibility to automatically migrate RRD files from v3 to v4.

A debconf question has been added to ask the user weather he wishes to let
collectd try to automatically migrate old RRD files using migrate-3-4.px. A
backup of /var/lib/collectd/ will be created in this case.

+Template: collectd/auto-migrate-3-4
+Type: boolean
+Default: false
+Description: Automatically try to migrate your RRD files?
+ The layout of the RRD files created by collectd has changed significantly
+ since version 3.x. In order to keep your old data you have to migrate it.
+ This can be done by using /usr/lib/collectd/utils/migrate-3-4.px. This step
+ can be done automatically. In this case a backup of /var/lib/collectd/ is
+ made in /var/backups/.
+ .
+ See /usr/share/doc/collectd/README.Debian for details.
+ .
+ This script is still experimental. Do not expect it to work in all cases.
