FS(1) OpenBSD Reference Manual FS(1)NAMEfs - Manage AFS directories
SYNOPSISfs [command] [args]
DESCRIPTION
The fs utility is used to manipulate the AFS filesystem. Note that the
fs utility does not modify the traditional UNIX filesystem, only files in
AFS.
The fs utility provides several commands:

Most fs commands accept the following general arguments:
[-cell cellname] Specifies which AFS cell to use, if the default
cell is not to be used.
[-noauth] Specifies that fs should not try to authenticate the
connection to the server. This may be useful with shell scripts,
or if there is a problem with the AFS cell. Note that the server
will reject many commands if -noauth is specified.
The syntax of the fs commands:
fs apropos
Locate commands by keyword
fs arladebug [flags] [-cell cellname] [-noauth]
Tweek arla-debugging flags.
fs checkservers [-cell cellname] [-noauth] [-nopoll]
Check if the servers in a cell are available. If -nopoll is
specified, the servers are not contactad; only internal information
is printed.
fs checkvolumes
Check that all volume mapping are correct and flush all mountpoints
from the cache to force them to be reread.
fs cleanacl
Not yet implemented.
fs copyacl
Not yet implemented.
fs diskfree path
Show free space on the partition where the file or directory path
is stored
fs examine [path]
Print detailed information about the volume mounted on the
specified path or the current directory.
fs flush file
Flush file from the cache, causing it to be stored on the
fileserver.
fs flushvolume file
Flush all the files in the volume where the file is stored, causing
them to be stored on the fileserver. Meta information about the
volume is also flushed.
fs gcpags
Remove unused PAGs from the kernel.
fs getcacheparms
Print information about cache usage.
fs getcrypt
Display whether traffic between the client and server is encrypted.
fs getcellstatus cellname
Indicate if the setuid bit on executable files are honored for the
specified cell.
fs getfid path
Print fid information for a file.
fs getserverprefs
Not yet implemented.
fs getstatistics
Get statistics from the cache manager. Possible type to get
statistics for are fetchstatus, fetchdata, storestatus, storedata,
bulkstatus.
fs getpriority
Display priority of a file or directory.
fs gp
Shorthand for the getpriority command
fs getmaxpriority
Display max priority for a file.
fs gmp [-cell cellname] [-noauth]
Shorthand for the getmaxpriority command.
fs help [-cell cellname] [-noauth]
Get help for fs
fs incompat
returns what interface of the pioctl interface currently is in use.
fs listacl path
Show acl for the specified path or the current directory.
fs la [-cell cellname] [-noauth]
Shorthand for the listacl command.
fs listcells
List cells that the cache handler can communicate with. These are
the cells listed in the file /etc/afs/CellServDB.
fs listquota [path]
Show the quota for the volume of the path specified.
fs lq [path]
Shorthand for the listquota command
fs quota [-cell cellname] [-noauth]
Shorthand for the listquota command.
fs lsmount path
Show a mount point.
fs messages
Not yet implemented.
fs mkmount directory volume [-cell cell] [-rw]
Create a mountpoint point to volume in optional cell. If -rw is
given, a mountpoint to the readwrite volume is created.
Note that there must not exist a directory named like the mount
point you are creating.
fs connect [mode]
Set or get connected mode, if a mode is specified, the cache
manager will be set to that mode. If not, the current mode will be
printed.
Valid modes are:
connected
Connected mode - this is the normal operating mode.
fetch
Fetch only mode - files are retrieved from fileserver but are
not stored back.
disconnected
Disconnected mode - files are read and written from/to the
cache, and no attempt is made to contact a fileserver-
Disconnected mode is very useful for machines that are not
connected to the network at all times, such as laptops.
Disconnected mode is to be considered very experimental at this
stage.
fs monitor
Not yet implemented.
fs newcell -cell cellname -servers vldb-servers [-help]
Add a new cell to the running configuration of the cache manager,
or update already existing information. This information should
also be entered in the file /etc/afs/CellServDB.
fs nop
Do a pioctl-nop. This is useful for debugging.
fs quit
Leave interactive mode.
fs exit
Leave interactive mode.
fs rmmount mountpoint
Delete mountpoint.
fs removepriority path
Remove priority from file or directory path.
fs rmp
Shorthand for the removepriority command.
fs setacl
Add an acl entry on a directory. Each entry consists of two
components: a user or group and a character string describing the
permissions granted for that user or group. These characters and
the permission they represent are:
r read the files
l list the files
i insert new files
d delete files
w write (change) the files
k lock files
a administer the acl, that is, to change the acl
There are also a few convinience strings recognized by fs setacl:
none removes all permissions.
read adds 'rl' permissions, which are suitable for a read-
only directory.
write adds all permissions except 'a', that is, the
user/group can read, write, delete etc. but not change
the acl of the directory.
all add all permissions.
Note that in AFS you set the permissions on a directory, and the
permissions of a file are those of their directory. So, if you
move a file from one directory to another, you might change the
permission of the file, as the two directories may have different
permissions.
Of the traditional UNIX permission bits only the user part is
honored, and is used for any user permissioned by the directorys
acl. The group and world permission bits are ignored, but they are
stored.
fs sa
Shorthand for the setacl command
fs setcachesize lowvnodes [highvnodes lowbytes highbytes]
Set the size of the disk cache.
fs setcell
Not yet implemented.
fs setpriority file priority
Set priority of a file/directory.
fs sp
Shorthand for the setpriority command.
fs setmaxpriority priority
Set upper limit of priority.
fs smq
Shorthand for the setmaxpriority command.
fs setquota path quota
Set the quota (in Kbytes) on a volume pointed out by path.
fs sq
Shorthand for the setquota command.
fs setserverprefs
Not yet implemented.
fs setcrypt yes | no
If no is specified, encryption of the traffic to/from fileservers
is disabled, and if yes is specified, it is enabled.
fs setvol
Not yet implemented.
fs suidcells
Print cells and whether setuid execution is allowed for them.
fs sysname [sysname]
Get or set the value of the '@sys' value.
fs version
Print version of fs and fs_lib.
fs venuslog
Make arlad print status.
fs whereis [path]
Show server(s) of the specified file or the current directory.
fs whichcell [path]
Show cell of a file or the current directory.
fs wscell
Display default cell of the client.
fs nnpfsdebug
Tweek nnpfs-debugging flags
fs nnpfsprint [flags]
Make nnpfs print debug info.
