DESCRIPTION
The sfop utility manages volumes, disk groups, and file systems. Using
the sfop utility, the administrator creates a pool of storage on which
file systems are created and mounted. These file systems are referred
to as pooled file systems. The multiple file systems created in the
storage pool have equal access to the free disk space.
sfop simplifies storage management by providing a single interface to
the administrator and by abstracting the administrator from many of the
commands needed to create and manage volumes, disks groups, and file
systems.
Cluster File System Issues
No cluster issues; command operates the same on cluster file systems.
KEYWORDS
dg create Creates a new disk group named dgname, using the specified
disks. Available disks can be listed using the dg listdisk
keyword. Disks are added to the specified autofspool or
fspool, depending on the --autofspool, --noautofspool, and
--fspool options. Disks after a :free: argument are explic‐
itly added as free disks in the disk group, which can be used
automatically for extending file system pools.
dg deport Detaches volumes and file systems in the specified disk
group, making them available to be attached to another sys‐
tem.
dg destroy
Detaches volumes and file systems in the specified disk
group, then destroys the disk group.
dg diskadd
Adds new disks to a disk group. Available disks can be
listed using dg listdisk. Disks before a :free: argument are
added to a pool specified with the --fspool=poolname option,
or to the autofspool for the disk group, if there is such a
pool. If there is no autofspool and for disks after :free:
disks are added as general free space to the disk group.
dg diskrm Remove disks from a disk group. Disks that are currently in
use within an fspool will first be removed from the pool.
dg import Attaches to volumes and file systems in the specified disk
group.
dg list Lists all disk groups known to the system on which the com‐
mand is run, or lists details about the specified disk
groups.
dg listdisk
Lists all disks for all disk groups if no disk group is spec‐
ified. Otherwise, lists disks for the specified disk group.
dg mirroron
Adds mirroring to the disk group. Available disks can be
listed using dg listdisk.
dg process
Process the specified disk groups known to this system. If
no disk group is specified, processes all disk groups known
to this system. Processing consists of mounting all file
systems associated with any file system pools, and cleaning
up any incomplete actions that may have resulted from a crash
or other failure.
fs clone Clones the named pool-based file systems, giving the clones a
name based on newname. If more than one file system is to be
cloned, newname must contain the pattern "{fs}", which will
be replaced by the original file system name. By default,
the file system clones will be mounted as
/fspool/dgname/[fspool/]fsname.
A different directory can be named by specifying mount=mount-
dir. A pool can also set an alternate default mount point.
fs create Creates a file system named fsname in the given pool, the
default pool for the named disk group, or the system default
disk group's default pool. By default, the file system will
be mounted as /fspool/dgname[fspool/]fsname. A different
directory can be named by specifying mount=mount-dir. Mount
options can be specified using an attribute of options=mount-
option[,mount-option]. A pool can also set an alternate
default mount point.
fs list Lists all file system pool-based file systems on the system,
in the specified disk group, or in the specified file system
pool, or lists the specified file system pool-based file sys‐
tems.
fs mount Mounts one or more pool-based file systems. Causes each file
system to use the mount point directory specified when the
file system was created, or to use the mount point last
requested by an fsmount call. An alternate mount point can
be specified with the mount=mount-dir option. If mount-dir
contains the pattern "{fs}", the pattern that will be
replaced with the file system name.
fs remove Removes a file system from a pool. Normally, this command
will print the name of the fully resolved file system name
and will ask the user to confirm the removal.
fs umount Unmounts one or more pool-based file systems.
OPTIONS-C Specifies the command keyword.
-T Specifies the type category keyword.
-f | --force
Forces an operation to proceed regardless if the operation
normally prompts for confirmation to proceed.
-g [[domain]:]dgname
Specifies the disk group scope. A prefix of domain: indi‐
cates explicit use of the that domain as a scope. A prefix
of only : indicates explicit use of this system's local
scope.
-n | --noremove | --nonremovable
Creates the clone as non-removable when specified with the fs
clone keyword. By default, if the file system udpates con‐
sume all available clones, clones are removed to avoid
returning out-of-space errors and to prevent corruption of
the clone images. Specifying -n, --noremove, or --nonremov‐
able for a particular clone causes out-of-space errors to be
returned instead.
-q Suppresses explanatory output.
-r | --ro | --readonly
Mounts a file system as read-only. By default clones are
mounted as read-only, while other file systems are mounted as
read-write.
-v Displays underlying commands as they run.
-w | --rw | --readwrite
Mounts a file system as writeable. By default clones are
mounted as read-only, while other file systems are mounted as
read-write.
-x Print extended information.
--autofspool[=poolname]
Creates a default file system pool with the dg create key‐
word, which will be used for all disks added to the disk
group that are not explicitly added as a spare disk or to
another pool. If poolname is not specified, an unnamed pool
is created that will be used whenever no pool name is given
when a name is otherwise required in the context of a disk
group. The default behavior of dg create is to create a
default unnamed autofspool.
--automount | --noautomount
If specified with the fs create, fs mount, or fs clone key‐
words, controls whether the file system will be remounted
automatically whenever the disk group is imported, such as on
a reboot. By default, the file system is automounted unless
--nomount is specified.
--fspool[=poolname]
Add disks to the pool named poolname. When used with the dg
create keyword, the specified pool will be created as part of
creating the disk group, and the initial set of disks will be
added to the pool. If --fspool is not specified and if
--noautofspool is specified, dg create creates a default pool
named default that contains all disks, unless an alternate
pool or the free pool is requested.
--help Displays detailed help.
--mount | --nomount
Specifies if the file system should be mounted with an fs
create or fs clone operation. By default, the file system
will be mounted.
--autofspool
If specified with dg create, the default pool is not created.
File system pools must be created and managed explicitly
using the --fspool option or by using the fspool create key‐
word.
--remove | --removable
If specified with fs create, creates the file system as
removable. When there is more than one file system created
in a pool, each consumes space from the pool and together
they can fill up the pool. If you have a low-priority file
system, you can mark it to be removed when the pool runs out
of space.
--sync Synchronizes the on-disk state to ensure that the data is
completely accurate. Specifying --sync may cause sfop to
take longer to complete the operation.
--trace=what
Traces commands or I/O.
