There's strongly suggestive evidence of two users on the mailing list hitting this. http://www.gluster.org/pipermail/gluster-users/2014-December/019934.html http://www.gluster.org/pipermail/gluster-users/2014-December/019940.html I've also heard of at least one Red Hat customer escalation related to this, but of course I couldn't disclose details even if I knew them. Are these users' setups extreme? I don't know, but I was seeing 16M files in a directory before I even came to Red Hat (five years ago) so I'm inclined to believe it's common enough to worry about today. More importantly, the frequency of users hitting this problem is only likely to increase. Both clusters and directories are likely to continue getting larger, requiring more bits on both sides of whatever dividing line we choose. Whether it's today or two years from today, sooner or later the numbers are going to catch up with us. _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxxx http://www.gluster.org/mailman/listinfo/gluster-devel
