Hi all,
I need some help by solving a strange problem:
Situation:
I wrote a scrip that uses rsync to send backups to another server.
It does something like:
/usr/bin/rsync -azi --numeric-ids --exclude tmp --exclude var/spool/ --delete
-e ssh root@10.0.0.65:/ /storage/volumes/65
The script has a source file that dictates which servers to backup. E.g.
several ip address are visited to copy data to a backup server.
When started on the commandline all works fine. All servers are backuped.
At the end of the script, a while statment combining a sleep and a date
statement suspenses the script up to the next day before a new run is started.
In practice the script just exits when reaching the end of the wait(s),
#!/bin/bash
rsync all servers
wait till next day
exit 1
This works fine under all Centos systems in previously and currently versions
in use, from Centos 5.x (using inttab) and Centos 6x (using Upstart)
Problem:
when run from upstart, the script works only with Centos versions lower than
6.3;
When running the script from upstart, rsync exists with a error 14, some error
that has something to do ipc codes. (What are ipc codes?)
The versions of rysnc are the same, 3.0.6.
As said when started from commandline, there is no error 14; all just works
fine.
The script is in use now for along period of time, dating from Centos 5.2.
Why is rsync exiting with an error 14 when run from upstart? Running it from
cron is no option because you always get problems with overlap or complicated
stuff to avoid dubble backups running. Upstart and inittab are fine tools for
just avoiding that.
BTW commands such as scp do run. Besides the rsync, scp is used to copy
serveral config files, that works fine. Just rsync fails.
Any help or suggestions are welcome. I already tried a lot of stuff but at this
moment I am out of any ideas to solve this.
Regards,
Bert.
