Hi, When my application moves a file from it's local disk to FUSE-mounted GlusterFS volume, the client outputs many warnings and errors not always but occasionally. The volume is a simple distributed volume. A sample of logs pasted: http://pastebin.com/axkTCRJX It seems to come from something like a network disconnection ("Transport endpoint is not connected") at a glance, but other networking applications on the same machine don't observe such a thing. So I guess there may be a problem somewhere in GlusterFS stack. It ended in failing to rename a file, logging PHP Warning like below: PHP Warning: rename(/glusterfs01/db1/stack/f0/13a9a2f0): failed to open stream: Input/output error in [snipped].php on line 278 PHP Warning: rename(/var/stack/13a9a2f0,/glusterfs01/db1/stack/f0/13a9a2f0): Input/output error in [snipped].php on line 278 Conditions: - GlusterFS 3.8.5 installed via yum CentOS-Gluster-3.8.repo - Volume info and status pasted: http://pastebin.com/JPt2KeD8 - Client machines' OS: Scientific Linux 6 or CentOS 6. - Server machines' OS: CentOS 6. - Kernel version is 2.6.32-642.6.2.el6.x86_64 on all machines. - The number of connected FUSE clients is 260. - No firewall between connected machines. - Neither remounting volumes nor rebooting client machines take effect. - It is caused by not only rename() but also copy() and filesize() operation. - No outputs in brick logs when it happens. Any ideas? I'd appreciate any help.
