这个参数是用来指定集群配置中的 GFS2 文件系统。它有两部分,用冒号隔开(没有空格)如下:ClusterName:FSName ClusterName,用来创建 GFS2 文件系统的集群名称。 FSName,文件系统名称,长度可在 1-16 个字符之间。该名称必须与集群中所有 lock_dlm 文件系统以及每个本地节点中的所有文件系统(lock_dlm 和 lock_noloc...
ignore_local_fs 注意:当共享 GFS2 文件系统时,不应该使用这个选项。 强制GFS2 将文件系统视为多主机文件系统。默认情况下,使用 lock_nolock 会自动打开 localflocks 标记。 localflocks 注意:当共享 GFS2 文件系统时,不应该使用这个选项。 告诉GFS2 让 VFS(虚拟文件系统)层完成所有 flock 和 fcntl ...

disk superblock. The cluster/filesystem name is recognized globally throughout the cluster, and establishes a unique namespace for the inter-node locking system, enabling the mounting of multiple GFS2 filesystems. The format of LockTableName is lock-module-specific. For lock_dlm, the format is...

When you create the GFS2 filesystem, it is important to specify a correct value for the-tLockTableNameoption. The correct format isClusterName:FSName. Failure to specify a correct value will prevent the filesystem from mounting. Additionally, the file system name must be u...
