autosupport.enable
Enables/disables the autosupport email notification
feature (see na_autosupport(8)). The
default is on to cause autosupport mail to be
sent.
autosupport.mailhost
Defines the list of up to 5 mailhost names.
The host names should be entered as a comma
separated list with no spaces in between.
The default is an empty list.
autosupport.to Defines the list of recipients for the autosupport email notification. Up to 5 mail addresses are allowed. Enter the addresses as a comma separated list with no spaces in between. The default is autosupport@netapp.com.
autosupport.noteto
Defines the list of recipients for the autosupport
short note email. Up to 5 mail
addresses are allowed. Enter the addresses as
a comma separated list with no spaces in
between. The default is a null list to disable
short note emails.
autosupport.from
Defines the user to be designated as the sender of the notification. The default is autosupport.
autosupport.doit
Triggers the autosupport daemon to send email
notification immediately. A text word entered
as the option is sent in the notification
subject line and should be used to explain
the reason for the notification.
cifs.generic_account
The cifs.generic_account
option can enable a user who has no password
account in /etc/passwd on the filer or in the
NIS password database to get access to the
filer, provided that the filer uses a Domain
Controller for authentication and the user is
in a trusted domain. If the option is set to
the name of an account, the user gets the
UNIX user ID, group ID, and group set of that
account. If the option is blank, generic
access is disabled.
cifs.guest_account
The cifs.guest_account option can enable a
user to get access to the filer provided that
either the filer uses a Domain Controller for
authentication and the user is not in a
trusted domain, or the filer uses the
/etc/passwd file or the NIS password database
for authentication and the user has no entry
in the /etc/passwd or the NIS password database.
If this option is set to the name of an
account in the password database, a user logging
into the filer will be assigned to the
guest account if their name is not listed in
the password database (when using /etc/passwd
or NIS) or if the user is not from a trusted
domain (when using a domain controller). The
configured user name will be used for the
UNIX user ID, group ID, and group set of the
specified account. If the option is blank,
guest access is disabled.
cifs.home_dir When set to the pathname of a directory, this defines the path to the ``homes directory''. The directories under this path should have the names of users as their names. When a user connects to the filer using CIFS and there is a directory name that exactly matches the user name, they will see a share of that name (truncated to 12 characters) that is their ``home directory". Only the user can access the home directory using this share. All other users are denied access.
cifs.oplocks.enable
When cifs.oplocks.enable is on (the default),
the filer allows clients to use oplocks
(opportunistic locks) on files. Oplocks are
a significant performance enhancement, but
have the potential to cause lost cached data
on some networks with impaired reliability or
latency, particularly wide-area networks. In
general, this option should be disabled only
to isolate problems.
cifs.scopeid NetBIOS scope IDs allow the system administrator to create small workgroups out of a network by partitioning the NetBIOS name space; only clients with the same NetBIOS scope ID as the filer will be able to use the filer as a CIFS server. Normally, the scope ID is a null string, but if the filer is to run in a NetBIOS scope other than the default one, its scope ID must be set to the scope ID of that scope. The scope ID can be changed only when CIFS is not running.
cifs.symlinks.cycleguard
The cifs.symlinks.cycleguard option (on by
default), eliminates the possibility of
traversing directories cyclically during the
following of symbolic links. With this
option set to on, the filer does not follow
symbolic links that contain the "dot" (`.')
or "dot-dot" (`..') component -- symbolic
links that could refer to a directory higher
in the same tree. With this option set to
off many standard windows apps (such as Find
in Win95 / NT4.0) will not operate correctly
when a symlink points to a parent directory.
This is because they do not understand symbolic
links and will repeatedly loop on them.
Users should use caution when changing this
option.
cifs.symlinks.enable
When cifs.symlinks.enable is on (the
default), if the object being accessed by a
CIFS client is a symbolic link (whether absolute
or relative), the filer follows the link
with the proviso that the ultimate target
turns out to reside within the originating
share (thus ensuring that the client has
access permission to the target).
dns.domainname Sets the DNS domainname to the specified domainname.
httpd.log.max_file_size
Specifies the maximum size that the HTTP log
file /etc/log/httpd.log can grow to. The
default is 2147483647, which is the largest
file size that many clients support.
httpd.rootdir Specifies the complete pathname of the root directory that contains files and subdirectories for HTTP access.
httpd.timeout Specifies the minimum amount of time (in seconds) before an idle HTTP connection will time out. The default is 900 seconds, which is fifteen minutes.
httpd.timewait.enable
When enabled, the filer will put HTTP connections
which have been closed by the client
into the TIME_WAIT state for one minute,
which is twice the maximum segment lifetime
(2*MSL). By default, TIME_WAIT state is
bypassed for HTTP connections.
nfs.mount_rootonly
When enabled, the mount server will deny the
request if the client is not root user using
privileged ports. By default, the feature is
enabled for more secure access.
nfs.per_client_stats.enable
Enables/disables the collection and display
of per-client NFS statistics as described in
na_nfsstat(1).
nfs.tcp.enable When enabled, the NFS server supports NFS over TCP. By default, the feature is enabled; it can be disabled if there is a problem with some client when using NFS over TCP, and that client cannot be configured to use NFS over UDP.
nfs.v2.df_2gb_lim
Causes the filer to return replies to the
"file system statistics" NFS version 2
request that show no more than (2**31)-1 (or
2,147,483,647) total, free, or available
bytes (i.e., 2GB) on the file system.
Some NFS clients require this option because, if they get return values from the "file system statistics" request with more than the specified number of bytes, they'll incorrectly compute the amount of free space on the file system, and may think that there's no free space on a file system that has more than 2GB free.
nfs.v3.enable When enabled, the NFS server supports NFS version 3. By default, the feature is enabled; it can be disabled if there is a problem with some client when using NFS version 3, and that client cannot be configured to use NFS version 2.
nfs.webnfs.enable
When enabled, the NFS server supports WebNFS
lookups. By default, WebNFS lookups are
disabled.
nfs.webnfs.rootdir
Specifies the WebNFS rootdir. Once the rootdir
is set, WebNFS clients can issue lookups
relative to the rootdir using the public
filehandle.
nfs.webnfs.rootdir.set
After specifying the rootdir, this option
needs to be enabled for the rootdir setting
to take effect. Disabling this option disables
the existing rootdir setting.
nis.domainname Sets the NIS domain to the specified domainname.
raid.reconstruct_speed
Specifies the speed at which the RAID reconstruction
should occur ranging from the
slowest speed 1 to the fastest speed possible
10. The RAID reconstruction process is given
more cpu time as the speed is increased, so
increasing the speed of the reconstruction
will take away cpu time for network
operations. The default speed is 4 which is
roughly 40% of the cpu time, though more time
may be used if there is idle time available.
raid.scrub.enable
Enables/disables the RAID scrub feature (see
na_disk(1)). By default, it is enabled. This
option only affects the scrubbing process
that gets started from cron. For user
requested scrubs, this option is ignored.
telnet.hosts Allows specifying up to 5 clients that will be allowed telnet access to the server. The host names should be entered as a comma separated list with no spaces in between. Enter a "*" to allow access to all clients; this is the default. Enter a "-" to disable telnet access to the server.
wafl.maxdirsize
Sets the maximum size (in K-Bytes) that a
directory can grow to. This is set to 10240
by default; it limits directory size to 10MBytes
and can hold over 300,000 files. Most
users should not need to change this setting.
This option is useful for environments where
system users may grow a directory to a size
that starts impacting system performance.
When a user tries to create a file in a
directory that is at the limit the system
returns a ENOSPC error and fails the create.
wafl.root_only_chown
When enabled, only the root user can change
the owner of a file. When disabled, non-root
users can change the owner of files that they
own. When a non-root user changes the owner
of a file they own, both the set-UID and
set-GID bits of that file are cleared for
security reasons. A non-root user is not
allowed to give away a file if it would make
the recipient overrun its user quota.
wafl.root_only_chown is enabled by default.
Multiple options can be set at once in an options command. For example:
toaster> options nfs.tcp.enable on nfs.v2.df_2gb_lim on raid.timeout 48
