We use the samba glusterfs virtual filesystem (the current version provided on download.gluster.org <http://download.gluster.org>), but no windows clients connecting directly.
Hmm.. Is there a way to disable using this and check if the CPU% still increases? What getxattr of "glusterfs.get_real_filename <filanme>" does is to scan the entire directory looking for strcasecmp(<filname>, <scanned-filename>). If anything matches then it will return the <scanned-filename>. But the problem is the scan is costly. So I wonder if this is the reason for the CPU spikes.

We have done that in the past to clean up an issues where gluster wouldn't allow us to delete from the mount. If so, is it feasible to clean them up by running a search on the .glusterfs directories directly and removing files with a reference count of 1 that are non-zero size (or directly checking the xattrs to be sure that it's not a DHT link). find /data/brick01a/homegfs/.glusterfs -type f -not -empty -links -2 -exec rm -f "{}" \; Is there anything I'm inherently missing with that approach that will further corrupt the system?

The volume's heal statistics output shows that it is crawling one of the bricks and trying to heal, but this crawl hangs and never seems to finish. The number of files in the xattrop directory varies over time, so I ran a wc -l as you requested periodically for some time and then started including a datestamped list of the files that were in the xattrops directory on each brick to see which were persistent.
