rmfdmn - removes a file domain
/sbin/rmfdmn [-f] domain
-f 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
+ 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 sys-
tem 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 follow-
ing is displayed:
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
You must be the root user to use this command.
To remove a domain, all filesets and clone filesets must be unmounted.
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 disks.]
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 label.
The following example removes the accounts_dmn file domain. In this exam-
ple, 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 removed
