|
|||
Checks that mirror-dir did it's job. Will send an email if not. |
|||
|
|||
Options: |
|||
DIR1 ... DIRn |
|||
Local directories that should be mirrored on destination(s). |
|||
|
|||
examples: /etc /home /var/backups |
|||
|
|||
If no directories are provided, the config file root |
|||
entries will be used all as destination to copy. |
|||
|
|||
-d DESTn |
|||
Can be repeated. Specifies host destination towards which |
|||
files will be send. Note that you can specify port number after |
|||
a colon and a bandwidth limit for rsync after a '/'. |
|||
|
|||
examples: -d liszt.musicalta:10022 -d 10.8.0.19/200 |
|||
|
|||
-n TIME_SPEC |
|||
Give a full english time spec about how old the last full |
|||
run of rsync should be at most. Defaults to '12 hours'. |

|||
examples: -n '12 hours' |

Hi, |
|||
|
|||
Some configured mirroring targets have not finished gracefully in |
|||
the last $time_spec. Please see for yourself: |
|||
|
|||
$( |
|||
for m in "${msg[@]}"; do |
|||
echo " $m" |
|||
done |
|||
) |
|||
|
|||
You might want to find these following information of some use: |
|||
|
|||
$( |
|||
|
|||
for m in "${bad_sessions[@]}"; do |
|||
if [ -e "${state_dir}"/$m-fail ]; then |
|||
echo " ${sessions[$m]}:" |
|||
tail -n 5 "${state_dir}"/$m-fail | cut -f 1,2,5- -d " " | sed -r "s/^/ /g" |
|||
echo |
|||
else |
|||
echo " ${sessions[$m]}: no fail log available" |
|||
fi |
|||
done |
|||
|
|||
) |
|||
|
|||
Hoping all this will help you sort out the issue... |
|||
|
|||
Yours sincerly, |
