Greetings Group! I hope this will be an easy one. To conserve steps in backing up the metadata extended attributes of a Lustre mdt, I am looking at using a newer version of tar combined with its --xattrs option. (Note: Previously I have used the mdt two-step back-up from the Lustre Manual and it has been successful.) If I can backup the extended attributes via tar so that I don't have to issue both a getfattr and then a tar command it would be convenient.
I have GNU tar-1.23. I was trying a version of the command indicated in http://lists.lustre.org/pipermail/lustre-discuss/2009-June/010794.html which supplied the --xattrs argument to the tar command. It failed with "Unrecognized option --xattrs". Is there something I need to specify to get tar to understand it is to back up extended attributes? Will this version of tar correctly obtain the extended attributes or should I be using lustre-tar tool instead? TIA, megan SGI Federal _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
