Dear Gluster Gurus, My eDiscovery app got 6 billions small files. Any suggestion to transfer them quickly into GlusterFS without "No such file" & "Invalid argument" errors?

Today's Topics: 1. 3.1.2 with "No such file" and "Invalid argument" errors (Steve Wilson) ---------------------------------------------------------------------- Message: 1 Date: Fri, 28 Jan 2011 12:49:03 -0500 From: Steve Wilson <stevew at purdue.edu> Subject: 3.1.2 with "No such file" and "Invalid argument" errors To: Gluster General Discussion List <gluster-users at gluster.org> Message-ID: <4D43018F.1020607 at purdue.edu> Content-Type: text/plain; charset="iso-8859-1"; Format="flowed" I'm running a pair of replicated/distributed GlusterFS 3.1.2 servers, each with 8 bricks. Here's the command I used to create the data volume: gluster volume create post replica 2 transport tcp pablo:/gluster/01/brick stanley:/gluster/01/brick \ pablo:/gluster/02/brick stanley:/gluster/02/brick \ pablo:/gluster/03/brick stanley:/gluster/03/brick \ pablo:/gluster/04/brick stanley:/gluster/04/brick \ pablo:/gluster/05/brick stanley:/gluster/05/brick \ pablo:/gluster/06/brick stanley:/gluster/06/brick \ pablo:/gluster/07/brick stanley:/gluster/07/brick \ pablo:/gluster/08/brick stanley:/gluster/08/brick The clients mount the volume using the gluster FUSE client, again version 3.1.2. Since GlusterFS doesn't yet support exporting sub-directories directly (it does now for NFS, though, I believe), I mount the volume as: /net/.post-volume and then bind mount a couple of lower sub-directories as: /net/post (bound to /net/.post-volume/home) /net/post-scratch (bound to /net/.post-volume/scratch) I am using this volume for user home directories. That's the background information... now for the problem. There are certain files that are almost guaranteed to go missing after less than a few hours of a user starting up a login session. We use Ubuntu with GDM as a login greeter and both KDE and Gnome desktops. Here are a few of the files that usually go missing: ls: .dmrc: No such file or directory ls: .pine-debug2: Invalid argument ls: .xsession-errors.old: No such file or directory ls: .recently-used.xbel: No such file or directory Taking .dmrc, for example, I can stop the volume, then remove all occurrences of this file on all the bricks on both servers. Then start up the volume again, start the user session again, and after a period of time (I'm not sure how long), the file comes up missing again. When the file is missing, this is what it looks like on the bricks themselves: server 1: root at stanley:/gluster# ls -l ./07/brick/home/stevew/.dmrc ---------T 1 stevew sysmgr 0 2011-01-28 08:24 ./07/brick/home/stevew/.dmrc root at stanley:/gluster# ls -l ./02/brick/home/stevew/.dmrc -rw-r--r-- 1 stevew sysmgr 25 2011-01-28 08:25 ./02/brick/home/stevew/.dmrc server 2: root at pablo:/gluster# ls -l ./07/brick/home/stevew/.dmrc ---------T 1 stevew sysmgr 0 2011-01-28 08:24 ./07/brick/home/stevew/.dmrc root at pablo:/gluster# ls -l ./02/brick/home/stevew/.dmrc -rw-r--r-- 1 stevew sysmgr 25 2011-01-28 08:25 ./02/brick/home/stevew/.dmrc Pertinent log messages are: server 1: net-.post-volume.log:[2011-01-28 08:16:28.899544] W [fuse-bridge.c:2432:fuse_xattr_cbk] glusterfs-fuse: 6318974: GETXATTR() /home/stevew/.dmrc => -1 (Invalid argument) server 2: net-.post-volume.log:[2011-01-28 08:10:58.74848] W [fuse-bridge.c:2432:fuse_xattr_cbk] glusterfs-fuse: 2428788: GETXATTR() /home/stevew/.dmrc => -1 (No such file or directory) Any thoughts or ideas?
