<div dir="ltr">Hello All,<div><br></div><div>I have been experiencing difficulty with high process utilization on the glusterfs and glusterfsd processes. 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.</div><div><br></div><div>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:</div><div><br></div><div>[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_access</div><div><br></div><div>While 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.</div><div><br></div><div>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?<br><div><br></div><div>Thank you.<br clear="all"><div><br></div>-- <br><div class="gmail_signature"><div dir="ltr">Kyle <div><div><br></div></div></div></div>
