That was my first thought. Although it might just be a ZFS feature too, given it's clever/modern design. > What are you using for RAID?

LSI 9260-8i cards in all of our nodes currently. 16x 3TB Hitachi SAS drives in RAID6+1S. > Not sure where the 90% figure comes from, surely it depends on the disk > capacity??? 90% is anecdotal based on history (the last ~10 years or so of my sysadminning). I originally thought it would be down to a hard value free, but the percentage appears to scale with storage (at least, so far it does - there may well be an upper limit, although by then I hope I'm free of legacy file systems like XFS). I'm also interested to hear of anyone using BtrFS, and if these problems exist there too (either in standard non-GlusterFS NAS units, or GlusterFS setups). -Dan _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://supercolony.gluster.org/mailman/listinfo/gluster-users
