rmfdmn - removes a file domain
/sbin/rmfdmn [-f] domain
Turns off the message prompt.
Specifies the name of an existing file domain.
Use the rmfdmn utility to remove an existing, but unused,
file domain and all its filesets from the system.
When you remove a file domain: The file domain and its
filesets are destroyed The directory entry for the file
domain in the /etc/fdmns file is deleted AdvFS volumes
which were assigned to the file domain are relabeled as
Before attempting to remove a file domain, unmount all
filesets and clone filesets from the domain using the
umount command. If you attempt to remove a file domain
that has mounted filesets or clone filesets, the system
does not remove the file domain. Instead, it displays an
error message indicating that a fileset is mounted.
For each file domain you attempt to remove, a prompt similar
to the following is displayed: rmfdmn accounts_dmn
rmfdmn: remove domain accounts_dmn? [yes/no]
If you answer n, the file domain remains. If you answer y,
it is removed. The default is n, the file domain remains.
The -f option is useful for scripts when you do not want
to be queried for each file domain. If you choose the -f
option, no message prompt is displayed. The rmfdmn command
operates as if you responded yes to the prompt.
You must be the root user to use this command.
To remove a domain, all filesets and clone filesets must
The rmfdmn command can leave a partially-removed domain in
the /etc/fdmns directory, for example, should there be a
system failure during the remove operation. If this happens,
the remnants of the removed domain are put in the
/etc/fdmns directory as a file with a name in this format:
rmfdmn.domain_name.processid. If you interrupt the rmfdmn
command or there is a system failure during its operation,
check the /etc/fdmns directory for domain names in this
format and use the rmfdmn command to delete them.
However, if a partially-removed domain has been in the
/etc/fdmns directory for some time, it can be risky to
remove it with the rmfdmn command: the partitions might
have been put back into use and deleting them would make
them unusable. [The rmfdmn command puts an unused option
in the fstype field of the disk label when it removes
In this case, use the rm -r command to remove the partially-recovered
domain. Unlike the rmfdmn command, the
rm command does not alter the fstype field of the disk
The following example removes the accounts_dmn file
domain. In this example, the accounts_dmn#credit_fs fileset
is mounted on the /mnt3 directory and must be
unmounted. When the verification prompt for removing the
accounts_dmn is displayed, yes is selected. # umount
/mnt3 # rmfdmn accounts_dmn # rmfdmn: remove domain
accounts_dmn? [yes/no] # rmfdmn: domain accounts_dmn
