If you have to do this routinely, look into robinhood.

Hello, I have been able to successfully use "lfs lsetfacl ....." to set and modify permissions on a Lustre file system quickly with a small system because the lfs is directed at the Lustre MDT. It is similar, I imagine, to using "lfs find..." to search a Lustre fs compared with a *nix "find..." command, the latter which must touch every stripe located on any OST. So, how do a change UID and/or GID over a Lustre file system? Doing a *nix find and chown seems to have the same detrimental performance. >lfs lgetfact my.file The above returns the file ACL info. I can change permissions and add a group or user access/perm but I don't know how to change the "header" information. (To see the difference in header information, one could try "lfs lgetfact --no-head my.file" which shows the ACL info without the header.) >lfs lsetfacl -muser:newPerson:rwx my.file The above adds user with those perms to the original user listed in the header info. This is using Lustre version 2.6.x (forgot minor number). on RHEL 6.5. Suggestions genuinely appreciated.
