Mac OS X : "get_xattr_names: llistxattr("some/path/here", 1024) failed" error

[daitheflu at free.fr]

Hi,

Sorry for re-opening this thread but I'm still trying to get rid of these errors.
I tried to remove the -A and the -X options but it doesn't make things better.

Do you guys have another idea ?

Thanks a lot,

Hi Henri, hi list,

Thanks a lot for your answer.

I did some testing during my spare time those last weeks and ended up compiling rsync 3.0.9 (with additionnal Mac OS X-related patches).
The difficulty I was facing seems to be related to this : https://bugzilla.samba.org/show_bug.cgi?id=6576 - this is why I tried with rsync 3.0.9

The result is amazing : I get only two errors instead of hundreds. Errors read :

rsync: copy_xattrs: lsetxattr(""/Volumes/backup/inProgress/mail"","com.apple.FinderInfo") failed: No such file or directory (2)
rsync: copy_xattrs: lsetxattr(""/Volumes/backup/inProgress/mail/.Trashes"","com.apple.FinderInfo") failed: No such file or directory (2)

Since I'm asking rsync to backup the "/some/path/mail" directory in "/Volumes/backup/inProgress", it's quite obvious that destination "/Volumes/backup/inProgress/mail" and "/Volumes/backup/mail/.Trashes" directories don't exist when building the file list. I don't think rsync should complain about it.

So I guess the itemizing process that was fixed with bug 6576 might still need some little work :)
Should I reopen the bug ?

Cheers, and thanks again for the help,

As a first step you could try removing the -A <--acls, preserve ACLs (implies --perms)> option. It could be that the source system and your system do not have the same users.

Also, based upon the error you are receiving, one other option to consider removing would be the -X <--xattrs preserve extended attributes>.

It is possible, that something else is causing the error which you are seeing. Hopefully, at least one other person on this list will have some ideas which you may find helpful.

As a starting point try removing the arguments listed above and report back.
