subdisk plex Oo Ar offset Oc Op Cm rename -Attach a plex to a volume, or a subdisk to a plex. -If offset is specified, the subdisk will be attached to the given offset within -the plex. -If rename is specified, the subdisk or plex will change name according to the -object it attaches to. -.It Ic checkparity Oo Fl f Oc Ar plex -Check the parity blocks of a RAID-5 plex. -The parity check will start at the -beginning of the plex if the -.Fl f -flag is specified, or otherwise at the location of the parity check pointer, -the first location at which plex's parity is incorrect. -All subdisks in the -plex must be up for a parity check. -.It Ic concat Oo Fl fv Oc Oo Fl n Ar name Oc Ar drives -Create a concatenated volume from the specified drives. -If no name is specified, a unique name will be set by -.Ic gvinum . -.It Ic create Oo Fl f Oc Op Ar description-file -Create a volume as described in -.Ar description-file . -If no -.Ar description-file -provided, opens an editor and provides the current -.Nm -configuration for editing. -The -.Fl f -flag will make gvinum ignore any errors regarding creating objects that already -exists. -However, in contrast to vinum, objects that are not properly named in the -.Ar description-file -will not be created when the -.Fl f -flag is given. -.It Ic detach Oo Fl f Oc Op Ar plex | subdisk -Detach a plex or subdisk from the volume or plex to which it is -attached. -.It Ic grow Ar plex device -Grow a plex by creating a gvinum drive and subdisk on device and attach it to -the plex. -If required by the plex organization, it will be put into the growable state. -.It Ic help -Provides a synopsis of -.Nm -commands and arguments. -.It Ic l | list Oo Fl rvV Oc Op Ar volume | plex | subdisk -.It Ic ld Oo Fl rvV Oc Op Ar drive ... -.It Ic ls Oo Fl rvV Oc Op Ar subdisk ... -.It Ic lp Oo Fl rvV Oc Op Ar plex ... -.It Ic lv Oo Fl rvV Oc Op Ar volume ... -List information about the relevant object(s). -The -.Fl r -flag provides recursive display, showing each object's subordinate objects in -proper relation. -The -.Fl v -and -.Fl V -flags provide progressively more detailed output. -.It Ic mirror Oo Fl fsv Oc Oo Fl n Ar name Oc Ar drives -Create a mirrored volume from the specified drives. -It requires at least a multiple of 2 drives. -If no name is specified, a unique name will be set by gvinum. -If the -.Fl s -flag is specified, a striped mirror will be created, and thus requires a -multiple of 4 drives. -.It Ic move | mv Fl f Ar drive subdisk Op Ar ... -Move the subdisk(s) to the specified drive. -The -.Fl f -flag is required, as all data on the indicated subdisk(s) will be destroyed as -part of the move. -This can currently only be done when the subdisk is -not being accessed. -.Pp -If a single subdisk is moved, and it forms a part of a RAID-5 plex, the moved -subdisks will need to be set to the -.Dq stale -state, and the plex will require a -.Ic start -command. -If multiple subdisk(s) is moved, and form part of a RAID-5 plex, the -moved disk(s) will need to be set to the -.Dq up -state and the plex will require a -.Ic rebuildparity -command. -If the subdisk(s) form part of a plex that is mirrored with other -plexes, the plex will require restarting and will sync once restarted. -Moving -more than one subdisk in a RAID-5 plex or subdisks from both sides of a -mirrored plex volume will destroy data. -Note that parity rebuilds and syncing -must be started manually after a move. -.It Ic printconfig -Write a copy of the current configuration to standard output. -.It Ic quit -Exit -.Nm -when running in interactive mode. -Normally this would be done by entering the -EOF character. -.It Ic raid5 Oo Fl fv Oc Oo Fl s Ar stripesize Oc Oo Fl n Ar name Oc Ar drives -Create a RAID-5 volume from the specified drives. -If no name is specified, a unique name will be set by -.Ic gvinum . -This organization requires at least three drives. -.It Ic rename Oo Fl r Oc Ar drive | subdisk | plex | volume newname -Change the name of the specified object. -The -.Fl r -flag will recursively rename subordinate objects. -.Pp -Note that device nodes will not be renamed until -.Nm -is restarted. -.It Ic rebuildparity Oo Fl f Oc Ar plex -Rebuild the parity blocks of a RAID-5 plex. -The parity rebuild will start at -the beginning of the plex if the -.Fl f -flag is specified, or otherwise at the location of the parity check pointer. -All subdisks in the plex must be up for a parity check. -.It Ic resetconfig Oo Fl f Oc -Reset the complete -.Nm -configuration. -.It Ic rm Oo Fl r Oc Ar volume | plex | subdisk -Remove an object and, if -.Fl r -is specified, its subordinate objects. -.It Ic saveconfig -Save -.Nm -configuration to disk after configuration failures. -.It Ic setstate Oo Fl f Oc Ar state volume | plex | subdisk | drive -Set state without influencing other objects, for diagnostic purposes -only. -The -.Fl f -flag forces state changes regardless of whether they are legal. -.It Ic start -Read configuration from all vinum drives. -.It Ic start Oo Fl S Ar size Oc Ar volume | plex | subdisk -Allow the system to access the objects. -If necessary, plexes will be synced and rebuilt. -If a subdisk was added to a running RAID-5 or striped plex, gvinum will -expand into this subdisk and grow the whole RAID-5 array. -This can be done without unmounting your filesystem. -The -.Fl S -flag is currently ignored. -.It Ic stop Oo Fl f Oc Op Ar volume | plex | subdisk -Terminate access to the objects, or stop -.Nm -if no parameters are specified. -.It Ic stripe Oo Fl fv Oc Oo Fl n Ar name Oc Ar drives -Create a striped volume from the specified drives. -If no name is specified, a unique name will be set by -.Ic gvinum . -This organization requires at least two drives. -.El -.Sh DESCRIPTION -The -.Nm -utility communicates with the kernel component of the GVinum logical volume -manager. -It is designed either for interactive use, when started without -command line arguments, or to execute a single command if the command is -supplied on the command line. -In interactive mode, -.Nm -maintains a command line history. -.Sh OPTIONS -The -.Nm -commands may be followed by an option. -.Bl -tag -width indent -.It Fl f -The -.Fl f -.Pq Dq force -option overrides safety checks. -It should be used with extreme caution. -This -option is required in order to use the -.Ic move -command. -.It Fl r -The -.Fl r -.Pq Dq recursive -option applies the command recursively to subordinate objects. -For example, in -conjunction with the -.Ic lv -command, the -.Fl r -option will also show information about the plexes and subdisks belonging to -the volume. -It is also used by the -.Ic rename -command to indicate that subordinate objects such as subdisks should be renamed -to match the object(s) specified and by the -.Ic rm -command to delete plexes belonging to a volume and so on. -.It Fl v -The -.Fl v -.Pq Dq verbose -option provides more detailed output. -.It Fl V -The -.Fl V -.Pq Dq "very verbose" -option provides even more detailed output than -.Fl v . -.El -.Sh ENVIRONMENT -.Bl -tag -width ".Ev EDITOR" -.It Ev EDITOR -The name of the editor to use for editing configuration files, by -default -.Xr vi 1 -is invoked. -.El -.Sh FILES -.Bl -tag -width ".Pa /dev/gvinum/plex" -.It Pa /dev/gvinum -directory with device nodes for -.Nm -objects -.El -.Sh EXAMPLES -To create a mirror on disks /dev/ada1 and /dev/ada2, create a filesystem, -mount, unmount and then stop -.Ic gvinum : -.Pp -.Dl "gvinum mirror /dev/ada1 /dev/ada2" -.Dl "newfs /dev/gvinum/gvinumvolume0" -.Dl "mount /dev/gvinum/gvinumvolume0 /mnt" -.Dl "..." -.Dl "unmount /mnt" -.Dl "gvinum stop" -.Pp -To create a striped mirror on disks /dev/ada1 /dev/ada2 /dev/ada3 and -/dev/ada4 named "data" and create a filesystem: -.Pp -.Dl "gvinum mirror -s -n data /dev/ada1 /dev/ada2 /dev/ada3 /dev/ada4" -.Dl "newfs /dev/gvinum/data" -.Pp -To create a raid5 array on disks /dev/ada1 /dev/ada2 and /dev/ada3, -with stripesize 493k you can use the raid5 command: -.Pp -.Dl "gvinum raid5 -s 493k /dev/ada1 /dev/ada2 /dev/ada3" -.Pp -Then the volume will be created automatically. -Afterwards, you have to initialize the volume: -.Pp -.Dl "gvinum start myraid5vol" -.Pp -The initialization will start, and the states will be updated when it's -finished. -The list command will give you information about its progress. -.Pp -Imagine that one of the drives fails, and the output of 'printconfig' looks -something like this: -.Pp -.Dl "drive gvinumdrive1 device /dev/ada2" -.Dl "drive gvinumdrive2 device /dev/???" -.Dl "drive gvinumdrive0 device /dev/ada1" -.Dl "volume myraid5vol" -.Dl "plex name myraid5vol.p0 org raid5 986s vol myraid5vol" -.Dl "sd name myraid5vol.p0.s2 drive gvinumdrive2 len 32538s driveoffset 265s" -.Dl "plex myraid5vol.p0 plexoffset 1972s" -.Dl "sd name myraid5vol.p0.s1 drive gvinumdrive1 len 32538s driveoffset 265s" -.Dl "plex myraid5vol.p0 plexoffset 986s" -.Dl "sd name myraid5vol.p0.s0 drive gvinumdrive0 len 32538s driveoffset 265s" -.Dl "plex myraid5vol.p0 plexoffset 0s" -.Pp -Create a new drive with this configuration: -.Pp -.Dl "drive gdrive4 device /dev/ada4" -.Pp -Then move the stale subdisk to the new drive: -.Pp -.Dl "gvinum move gdrive4 myraid5vol.p0.s2" -.Pp -Then, initiate the rebuild: -.Pp -.Dl "gvinum start myraid5vol.p0" -.Pp -The plex will go up form degraded mode after the rebuild is finished. -The plex can still be used while the rebuild is in progress, although requests -might be delayed. -.Pp -Given the configuration as in the previous example, growing a RAID-5 or STRIPED -array is accomplished by using the grow command: -.Pp -.Dl "gvinum grow myraid5vol.p0 /dev/ada4" -.Pp -If everything went ok, the plex state should now be set to growable. -You can then start the growing with the -.Ic start -command: -.Pp -.Dl "gvinum start myraid5vol.p0" -.Pp -As with rebuilding, you can watch the progress using the -.Ic list -command. -.Pp -For a more advanced usage and detailed explanation of gvinum, the -handbook is recommended. -.Sh SEE ALSO -.Xr geom 4 , -.Xr geom 8 -.Sh HISTORY -The -.Nm -utility first appeared in -.Fx 5.3 . -The -.Nm vinum -utility, on which -.Nm -is based, was written by -.An "Greg Lehey" . -.Pp -The -.Nm -utility -was written by -.An "Lukas Ertl" . -The -.Ic move -and -.Ic rename -commands and -documentation were added by -.An "Chris Jones" -through the 2005 Google Summer -of Code program. -A partial rewrite of gvinum was done by -.An "Lukas Ertl" -and -.An "Ulf Lilleengen" -through the 2007 Google Summer of Code program. -The documentation have been updated to reflect the new functionality. -.Sh AUTHORS -.An Lukas Ertl Aq Mt le@FreeBSD.org -.An Chris Jones Aq Mt soc-cjones@FreeBSD.org -.An Ulf Lilleengen Aq Mt lulf@FreeBSD.org -.Sh BUGS -Currently, -.Nm -does not rename devices in -.Pa /dev/gvinum -until reloaded. -.Pp -The -.Fl S -initsize flag to -.Ic start -is ignored. -.Pp -Moving subdisks that are not part of a mirrored or RAID-5 volume will -destroy data. -It is perhaps a bug to permit this. -.Pp -Plexes in which subdisks have been moved do not automatically sync or -rebuild parity. -This may leave data unprotected and is perhaps unwise. -.Pp -Currently, -.Nm -does not yet fully implement all of the functions found in -.Nm vinum . -Specifically, the following commands from -.Nm vinum -are not supported: -.Bl -tag -width indent -.It Ic debug -Cause the volume manager to enter the kernel debugger. -.It Ic debug Ar flags -Set debugging flags. -.It Ic dumpconfig Op Ar drive ... -List the configuration information stored on the specified drives, or all -drives in the system if no drive names are specified. -.It Ic info Op Fl vV -List information about volume manager state. -.It Ic label Ar volume -Create a volume label. -.It Ic resetstats Oo Fl r Oc Op Ar volume | plex | subdisk -Reset statistics counters for the specified objects, or for all objects if none -are specified. -.It Ic setdaemon Op Ar value -Set daemon configuration. -.El diff --git a/sbin/gvinum/gvinum.c b/sbin/gvinum/gvinum.c deleted file mode
