Hi,
Could you provide the following pieces of information?
1. The brick and client logs
2. output of `gluster volume info`
3. average number of entries under directories
Just to be clear, you don't have quota enabled on the volume, do you?

Subject: Re: glusterfs and glusterfsd process utilizationI haven't heard anything from anyone re this post yet so I have a bit more info to add. The last time I posted about extremely high process utilization for glusterfs and glusterfsd, I was asked to see if I could capture the output of a profile. I did so and here is the output of 2 captures (they appear very similar). Perhaps this will assist. Note that previously I was mounting with the fuse client. This time I tried NFS.Profile Output 1:Brick: 192.168.10.92:/export/brick1-----------------------------------Cumulative Stats:Block Size: 1b+ 2b+ 4b+No. of Reads: 0 0 0No. of Writes: 133 6 37Block

I thought I had it tracked down to Apache looking for files on the cluster drive that don't exist. I have been working to clean that up and now I have discovered another problem.When I reboot one of the nodes in my 3-node replicated cluster, as soon as it comes back up I see a bunch of entries such as follows:[2014-12-21 05:33:49.873989] I [dict.c:370:dict_get] (--> /usr/lib64/libglusterfs.so.0(_gf_log_callingfn+0x1e0)[0x7fe3bd0d2420] (--> /usr/lib64/libglusterfs.so.0(dict_get+0x4f)[0x7fe3bd0cbbdf] (--> /usr/lib64/glusterfs/3.6.1/xlator/system/posix-acl.so(posix_acl_lookup_cbk+0x1e1)[0x7fe3aad3ada1] (--> /usr/lib64/glusterfs/3.6.1/xlator/debug/io-stats.so(io_stats_lookup_cbk+0x113)[0x7fe3aaf524e3] (--> /usr/lib64/glusterfs/3.6.1/xlator/performance/md-cache.so(mdc_lookup+0x300)[0x7fe3ab167310] ))))) 0-dict: !this || key=system.posix_acl_accessWhile this is occurring, the process utilization for glusterfs and glusterfsd go sky high. Eventually they calm down on their own but the servers are virtually unusable until they do. Note this is on Centos 6.6 with Gluster 3.6.1 and kernel 2.6.32 using a fuse mount with each of the 3 servers having the client mounted for hosting web sites via Apache. There are many small files and some are php. I have not done any tuning to the default gluster parameters.Can someone tell me why this occurs after one of the nodes is rebooted and perhaps lend some guidance on what can be done to resolve this issue?Thank you.--Kyle--Kyle A.
