You're right. I misremembered the commands. "attr" is the XFS variation of the same thing (except that attr prepends a "user." or "root." prefix to the name before calling getxattr() in order to make distinct namespaces for users and superusers). "getfattr" is the more standard tool. So, the proper snippet should've been: % getfattr -n readcap . # file: . readcap="URI:DIR2-RO:xxx...:yyy..." And I think it's quite powerful to be able to do: % tahoe check `getfattr -n readcap --only-values somefile` Summary: Healthy storage index: qggq5w4ynbxo6x2ns3ydv3uyq4 good-shares: 12 (encoding is 3-of-12) wrong-shares: 0 -- Scott Dial [email protected] [email protected] _______________________________________________ tahoe-dev mailing list [email protected] http://tahoe-lafs.org/cgi-bin/mailman/listinfo/tahoe-dev
