being mounted. This option is required only when the device driver is incapable of deter-
mining the size of special , and defaults to the entire device if not specified.
Note:
snapsize=size is available only with the HP OnLineJFS product.
suid|nosuid
setuid execution allowed or setuid execution not allowed. The default is
suid.
tranflush
When VxFS is the default boot file system
(/stand) on HP-UX, there can be no intent log
replay during the initial stages of the boot process. To ensure data and metadata con-
sistency during the boot process, the
tranflush
option flushes all metadata updates to
disk before returning from a system call. The tranflush option therefore enables VxFS
to approximate the behavior of a file system with no intent logging functionality. The
tranflush option automatically enables the
blkclear and log options. It is advisable
to specify the
mincache=dsync
mount option with tranflush. tranflush must be
explicitly specified when remounting the file system.
The
tmplog, delaylog, and datainlog mount options do not operate with
tran-
flush. The tranflush option does not operate on read-only file systems or cluster file sys-
tems.
EXAMPLES
List the file systems currently mounted:
mount
Mount a VxFS file system /dev/dsk/c1t2d0
at directory /home
mount -F vxfs /dev/dsk/c1t2d0 /home
Unmount the same file system:
umount /dev/dsk/c1t2d0
To unmount a file system, unmount the Storage Checkpoint first:
umount /ckptdir
umount /fsdir
Mount a Storage Checkpoint of a cluster file system on a VERITAS Volume Manager volume:
mount -F vxfs -o cluster,ckpt=ckpt_name \
/dev/vx/dsk/dg_name/volume_name:ckpt_name /ckpt_mount_point
Automatically mount Storage Checkpoints when the system reboots. You can list them in the
/etc/fstab file as in the following example:
/dev/vx/dsk/fsvol /fsdir vxfs defaults 0 2
/dev/vx/dsk/fsvol:myckpt /ckptdir vxfs ckpt=myckpt 0 0
FILES
/etc/fstab Static information about the file systems
/etc/mnttab Mounted file system table
