Description Ingo Steuwer

2014-07-17 09:36:29 CEST

The CRON job for univention-samba4-backup sends "from time to time" (about 2-3 times per month) a failure mail:

tar: ./private: file changed as we read it


System is a UCS DC Master 3.2-2 Errata 150

univention-samba4-backup now ignores the "file changed as we read it" from tar.

Also, tdb are backuped with tdbbackup.

Merged to UCS 4.0

YAML: 2014-08-28-univention-samba4.yaml

Is it possible to get the patch prior to the release of UCS 4 to add the changes manually in 3.2-3 errata185.

This fix is for errata3.2-3 (see target milestone). So depending on how fast we can verify this bug, this should be released with one of the next errata updates.

p.s.
Basically what i did was to add the "--warning=no-file-changed" switch to the tar command.
