mount_vxfs(1M) mount_vxfs(1M)
mounted. This option is required only when the device driver is incapable of determining 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 consistency
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 approxi-
mate 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
