Extended attributes limit in Linux

[Sun_Blood <sblood@xxxxxxxxx>]

Hello,

If I understands it correctly XFS don't have a limit to the size of extended attributes(EA) but Linux impose a limit at 64k.

What I am trying to do is build a backup server that our Apple computers will use together with rsync to backup files to. The problem I face is that Apple HFS+ don't have a limit to EA so it has files with more then 64k of EA in it.

The Linux Kernel has a limit imposed to it in include/linux/limits.h

#define XATTR_SIZE_MAX 65536    /* size of an extended attribute value (64k) */

#define XATTR_LIST_MAX 65536    /* size of extended attribute namelist (64k) */

Changing this values feels unsafe because they will be system wide.

Is the any possibility to combine Linux + XFS to make a backup that works with EA or is this more a question for kernel.org?

Thanks.
