And I can report that multiple exports are now working fine for us using the xrootd from ROOT 4.02-00. This was a mistake on my part. We originally had anecdotal evidence that multiple exports didn't work at one point in time, and that mixed with mistakes in our configuration file led me to the wrong conclusion. -Matt -----Original Message----- From: Andrew Hanushevsky [mailto:[log in to unmask]] Sent: Sunday, February 27, 2005 1:18 PM To: Pavel Jakl Cc: Peter Elmer; Langston, Matthew David; xrootd-l Subject: Re: How do we export multiple directories from xrootd.cf Hi Pavel, I'm not sure what version you are running but xrootd supported multiple directories for quite a long time. Simply list each directory you want to export with the export directory. For example: xrootd.export /a/b/c xrootd.export /d/e Andy On Sun, 27 Feb 2005, Pavel Jakl wrote: > Peter Elmer wrote: > > > Hi Matt, > > > >On Sun, Feb 27, 2005 at 09:03:29AM -0800, Langston, Matthew David wrote: > > > > > >>We would like to export multiple directories from our xrootd server.
