I'll let Dave answer this one. > Also, what would you like me to do with the xfs_db freesp output for 26 > agroups? A pastebin link should be fine. Only a couple of people will be looking at it. I don't see value in free space maps of 26 AGs being archived. FWIW, it's probably best to reply-all instead of just to the list. Sometimes posts get lost in the noise. Not sure if that's the case here, but it's been a couple of days with no response from Dave C, and the answers to these questions are very short. Thus I'm guessing he missed your post, so I'm CC'ing him here. -- Stan _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
