Rsync push task fails with Delete option selected

[Derek Humes]

Hi, I have searched the forums but have been unable to find any other information on this error I am seeing.

I am currently running FreeNAS-9.10.2-U4 (27ae72978)

I have an Rsync job that runs to copy a directory from my FreeNAS box to a volume located on a machine in my office. This job works correctly if I do NOT have the Delete option selected in the Rsync task configurations. However, if I enabled the Delete option, the job fails to start, and /var/log/messages indicates failure to start due to an rsync syntax error.

I am fairly new to FreeNAS, FreeBSD, and generally all Unix/Linux.

Is there somewhere else I should be looking for more logging information?

Thank you,

Could you share some more information about what it is you are doing? Are both of these systems running the same version of FreeNAS?
Are you configuring the rsync through the GUI?
Can you give the exact text of the error as that might help determine the cause?

 

[Derek Humes]

The other system is a Mac Mini with an attached USB external hard drive. I am using Rsync to push copy the contents of this directory daily to the externally attached usb drive.

Yes I am configuring Rsync through the GUI.

Code:

 Sep 18 12:00:00 KCANPFNAS001 rsync: rsync: on remote machine: --delete-delay: un
known option

Is this error showing up on the Apple side or on the FreeNAS side?

 

[Derek Humes]

FreeNAS side.

 

[Chris Moore]

Take a look at the Apple documentation for rsync:
https://developer.apple.com/legacy/library/documentation/Darwin/Reference/ManPages/man1/rsync.1.html
They did not implement the --delete-delay functionality.
FreeNAS, on the other hand, uses the FreeBSD version of rsync:
https://www.freebsd.org/cgi/man.cgi...ath=FreeBSD+8.0-RELEASE+and+Ports&format=html
The two software packages are not exactly the same, so what is happening is that FreeNAS is telling the Apple to do something that the Apple doesn't know how to do.
That is why there is an error. It is exactly what it says, "--delete-delay: unknown option"...

 

[Chris Moore]

You could try to get those guys at Apple to update their software.

If the GUI delete option is specifying --delete-delay by default, could I in theory then use the "Extra options" box in the GUI Rsync task to add simply --delete, or --delete-after, as the mac documentation you referenced probably would prefer?

That is something I have not tried. I hope someone else can comment. @Ericloewe ?

 

[Ericloewe]

I don't know, I don't use rsync, so I'm not at all familiar with its options.

 

[Derek Humes]

I did try adding --delete to the Extra options section and it does indeed work that way, FYI.
