Lala, what information would you like from the Gluster Bug Triage 'group'? Nothing in specific. While I was triaging the bug, I thought it would be a good candidate from group triage. This still occurs in 3.7.6 (release 1.el7). Renaming a symlink results in 2 symlinks (original & renamed). Deleting the parent directory of the symlink results in the recreation of the parent directory and symlink. However, the renamed symlink does not reappear in the recreated parent directory (only the original symlink). Type: Distributed-Replicate Number of Bricks: 2 x 2 = 4 Options Reconfigured: cluster.metadata-self-heal: on cluster.entry-self-heal: on cluster.data-self-heal: on cluster.self-heal-daemon: on cluster.self-heal-window-size: 32 performance.flush-behind: off cluster.lookup-unhashed: off cluster.readdir-optimize: on performance.io-thread-count: 32 performance.write-behind-window-size: 1GB performance.cache-size: 8GB performance.readdir-ahead: on nfs.disable: on This bug is getting closed because the 3.5 is marked End-Of-Life. There will be no further updates to this version. Please open a new bug against a version that still receives bugfixes if you are still facing this issue in a more current release. |
Description of problem: two replicated bricks provides volume www, mounted on client node as /var/www via fuse.glusterfs (glusterfs defaults,_netdev). rsync deploys about 9300 php files to directory /var/www/backend/releases/<new-time-stamp> on client node, and then relinks (symlink) /var/www/backend/current as this uploaded <new-time-stamp> dir like this: cd /var/www/backend && ln -s releases/20140911151733 /var/www/backend/current_tmp && mv -Tf /var/www/backend/current_tmp /var/www/backend/current please note that symlink 'current' already existed and pointed to another dir in /var/www/backend/releases/ when command above was run. What happens is that instead of getting new symlink 'current' pointing to newly uploaded source, we get directory 'current' that cannot be deleted - 'rm -fr current' succeeds, but it reappears second later. The only way to remove 'current' is to shut down all nodes, stop glusterfs[d] and remove directory on bricks themselves. This is critical as we have to kill whole cluster. Version-Release number of selected component (if applicable): 3.5.2-ubuntu1~trusty1, amd64 Actual results: 'current' appears as directory, cannot be deleted Expected results: 'current' should appear as link that points to new directory Additional info: all nodes are ubuntu 14.04LTS amd64 VM's, having at least 1GB of free memory left. Two mirrored bricks are glusterfs v3.5.2. Four client nodes mounts volume via NFS, deployment node (where rsync and commands below runs) mounts volume as glusterfs. full source deployment script that causes problem: * executing `deploy:copy_remote_cache' * executing "rsync -az --delete /var/www/backend/shared/cached-copy/ /var/www/backend/releases/20140911151733/" * executing "chmod -R g+w /var/www/backend/releases/20140911151733" * executing "sh -c 'if [ -d /var/www/backend/releases/20140911151733/var/cache ] ; then rm -rf /var/www/backend/releases/20140911151733/var/cache; fi'" * executing "sh -c 'mkdir -p /var/www/backend/releases/20140911151733/var/cache && chmod -R 0777 /var/www/backend/releases/20140911151733/var/cache'" * executing "chmod -R g+w /var/www/backend/releases/20140911151733/var/cache" * executing "find /var/www/backend/releases/20140911151733/web/css /var/www/backend/releases/20140911151733/web/images /var/www/backend/releases/20140911151733/web/js -exec touch -t 201409111521.41 {} ';' &> /dev/null || true" * executing "cd /var/www/backend && ln -s releases/20140911151733 /var/www/backend/current_tmp && mv -Tf /var/www/backend/current_tmp /var/www/backend/current"
