fs_mount_retry_count
The number of mount retries for each file system. The
default is zero. Details in Chapter 6 under
“fs_mount_retry_count” on page 212.
fs_umount_retry_count
The number of unmount retries allowed for each file
system during package shutdown. The default is zero.
(Logical volumes, file systems and mount options)
You can configure the package to activate one or more
storage groups on startup, and to mount logical
volumes to file systems. At halt time, the script
unmounts the file systems and deactivates each
storage group. All storage groups must be accessible on
each target node.
Four types of file system (fs_type) are supported:
• ext2, the basic Linux file system
• ext3, a journaling file system that improves
performance when the file system is fsck’d
• reiserfs, a journaling file system with B-tree data
storage
• gfs, Red Hat GFS
ext3 is the default for Red Hat. reiserfs is the default
for SUSE.
For each file system of type ext2, ext3, or reiserfs,
you must identify a logical volume, the mount point,
the mount, umount and fsck options and the type of the
file system; for example:
fs_name /dev/vg01/lvol1
fs_directory /pkg01aa
fs_type "ext2"
fs_mount_opt "-o rw"
fs_umount_opt ""
fs_fsck_opt ""
