Hi,
I have made some more tests:
./testxattr /u00/root.20121121.210102.full/var/lib/nfs/sm
processing file /u00/root.20121121.210102.full/var/lib/nfs/sm
processing attribute system.posix_acl_default
lgetxattr failed: No data available
getfattr /u00/root.20121121.210102.full/var/lib/nfs/sm
(no result)
setfattr -x system.posix_acl_default
/u00/root.20121121.210102.full/var/lib/nfs/sm
testxattr /u00/root.20121121.210102.full/var/lib/nfs/sm
processing file /u00/root.20121121.210102.full/var/lib/nfs/sm
processing attribute system.posix_acl_access
setfattr -x system.posix_acl_access
/u00/root.20121121.210102.full/var/lib/nfs/sm
./testxattr /u00/root.20121121.210102.full/var/lib/nfs/sm
processing file /u00/root.20121121.210102.full/var/lib/nfs/sm
Now a test with a manually set attribute:
setfattr -n user.testattribute -v testvalue
/u00/root.20121121.210102.full/var/lib/nfs/sm
getfattr /u00/root.20121121.210102.full/var/lib/nfs/sm
getfattr: Removing leading '/' from absolute path names
# file: u00/root.20121121.210102.full/var/lib/nfs/sm
user.testattribute
./testxattr /u00/root.20121121.210102.full/var/lib/nfs/smprocessing file
/u00/root.20121121.210102.full/var/lib/nfs/sm
processing attribute user.testattribute
value testvalue
Thanks in advance,
David Arendt
