红帽全球峰会7.6. 为故障排除收集 GFS2 数据
如果您的 GFS2 文件系统挂起，且不会返回针对它运行的命令，您应该收集以下数据并创建一个红帽支持问题单：
每个节点中的文件系统的 GFS2 锁定转储数据：
cat /sys/kernel/debug/gfs2/fsname/glocks >glocks.fsname.nodename
cat /sys/kernel/debug/gfs2/fsname/glocks >glocks.fsname.nodenameCopy to Clipboard Copied! Toggle word wrap Toggle overflow 每个节点上的文件系统的 DLM 锁定转储数据：您可以使用
dlm_tool获取此信息：dlm_tool lockdebug -sv lsname
dlm_tool lockdebug -sv lsnameCopy to Clipboard Copied! Toggle word wrap Toggle overflow 在这个命令中，lsname 是有问题的文件系统中 DLM 使用的锁定空间名称。您可以在
group_tool命令的输出中找到这个值。-
sysrq -t命令的输出。 -
/var/log/messages文件的内容。
收集到这些数据后，创建一个红帽支持问题单。
