Defines a file system mount. Symbolic name for this file system. File System Name Path in file system heirarchy to mount this file system. Mount Point Block device, file system label, or UUID of file system. Device or Label File system type. If not specified, mount(8) will attempt to determine the file system type. File system type If set, the cluster will kill all processes using this file system when the resource group is stopped. Otherwise, the unmount will fail, and the resource group will be restarted. Force Unmount Use quick status checks. When set to 0 (the default), this agent behaves normally. When set to 1, this agent will not log errors incurred or perform the file system accessibility check (e.g. it will not try to read from/write to the file system). You should only set this to 1 if you have lots of file systems on your cluster or you are seeing very high load spikes as a direct result of this agent. Quick/brief status checks. If set and unmounting the file system fails, the node will immediately reboot. Generally, this is used in conjunction with force_unmount support, but it is not required. Seppuku Unmount If set and unmounting the file system fails, the node will try to kill lockd and issue reclaims across all remaining network interface cards. Enable NFS lock workarounds If set and unmounting the file system fails, the node will try to restart nfs daemon and nfs lockd to drop all filesystem references. Use this option as last resource. This option requires force_unmount to be set and it is not compatible with nfsserver resource. Enable NFS daemon and lockd workaround File system ID for NFS exports. This can be overridden in individual nfsclient entries. NFS File system ID If set, the file system will be checked (even if it is a journalled file system). This option is ignored for non-journalled file systems such as ext2. Force fsck support Options used when the file system is mounted. These are often file-system specific. See mount(8) for supported mount options. Mount Options Use findmnt to determine if and where a filesystem is mounted. Disabling this uses the failback method (should be used if autofs maps are located on network storage (ie. nfs, iscsi, etc). Utilize findmnt to detect if and where filesystems are mounted EOT } verify_fstype() { # Auto detect?
