[Ocfs2-test-devel] [PATCH 33/59] xattr-multiple-run: fix Operation not permitted error

[Eric Ren]

Hi Junxiao & all,

Yes, trusted extended attributes are visible and accessible
only to processes that have the CAP_SYS_ADMIN capability.

Reviewed-by: Eric Ren <zren at suse.com>

BTW, it's also depending on the way we run test suits.
1. run as root. It make things much easy, but not safe.
   Also depends on openmpi version - 1.8 add an option
   "--allow-run-as-root" over 1.7. So, it's not a good way.

2. chmod 777 /dev/sdax by root

In both way, we didn't encournter this problem. I'm wondering how you
run testing. Little worry about if testing will stop to await
typing sudo password in your way. Are we free over this?

Thanks,
Eric Ren
