This is supported from SGLX_00354.tar.shar patch and later.
Supported types are ext3, XFS file system (on Red Hat Enterprise Linux 6 and
later, and SUSE Linux Enterprise Server 11), ext4 (on Red Hat Enterprise
Linux 5 and later), reiserfs, and gfs.
Red Hat GFS and reiserfs are not supported in Serviceguard A.11.20.00 version.
WARNING! ext4 file system has a delayed allocation mechanism. Hence, the behavior of
writing files to disk is different from ext3. Unlike ext3, the ext4 file system does not write data
to disk on committing the transaction, so it takes longer for the data to be written to the disk. Your
program must use data integrity calls such as fsync() to ensure that data is written to the disk.
NOTE: A package using gfs (Red Hat Global File System, or GFS) cannot use any other file
systems of a different type. vg and vgchange_cmd (page 186) are not valid for GFS file systems.
For more information about using GFS with Serviceguard, see Clustering Linux Servers with the
Concurrent Deployment of HP Serviceguard for Linux and Red Hat Global File Systems for RHEL5
at http://www.hp.com/go/linux-serviceguard-docs.
See also concurrent_fsck_operations (page 187), fs_mount_retry_count and
fs_umount_retry_count (page 187), and fs_fsck_opt (page 189).
See the comments in the package configuration file template for more information.
6.1.4.45 fs_mount_opt
The mount options for the file system specified by fs_name. See the comments in the configuration
file for more information. This parameter is in the package control script for legacy packages.
6.1.4.46 fs_umount_opt
The umount options for the file system specified by fs_name. See the comments in the configuration
file for more information. This parameter is in the package control script for legacy packages.
6.1.4.47 fs_fsck_opt
The fsck options for the file system specified by fs_name. Not used for Red Hat GFS (Red Hat
GFS is not supported in Serviceguard A.11.20.00) (see fs_type). This parameter is in the package
control script for legacy packages.
NOTE: A package using XFS file system must use xfs_repair command options as fsck
command on XFS does not work.
For more information, see the fsck and xfs_repair manpage, and the comments in the
configuration file.
