Stopping (Unmounting) a Fileset
Stopping (Unmounting) a Fileset
You stop an existing, mounted fileset to make it unavailable to users. This action is
also known as unmounting a fileset.
You stop a fileset under any of the following conditions:
•
Before diagnosing the fileset.
•
To make the files in the fileset unavailable to users. If a fileset is stopped while
users have files open in that fileset, the open files can be used normally. However,
once a file is closed, the file cannot be reopened until the fileset is mounted again.
•
To free memory in the OSS name server for that fileset.
•
To delete the fileset from the OSS file system.
If your site uses the STOPOSS utility, that utility stops all filesets. See STOPOSS Utility
on page C-16 for more information.
Alternatively, you can use the SCF STOP FILESET command to manually stop a
fileset:
1. Warn your users to make sure that all their files in the fileset are closed and all
OSS shell sessions using that fileset are terminated. You can use a method similar
to the one described under Manually Stopping the OSS File System and the OSS
Environment on page 2-3.
2. Do one of the following:
•
If the fileset is the root fileset, stop all filesets by entering the following OSS
Monitor SCF command:
STOP FILESET $ZPMON.*
•
If the fileset is not the root fileset, use the SCF STOP FILESET command.
For example, to stop (unmount) the fileset USER1 and send informational
messages to the file CMDLOG, enter the following SCF command:
STOP /OUT CMDLOG/ FILESET $ZPMON.USER1
If a user remains logged in with a current working directory in the stopped fileset, that
user might need to use the cd command again to return to the directory after the fileset
is restarted; otherwise, files in the restarted fileset might not be accessible to the user.
Reconfiguring a Fileset
You can reconfigure a fileset by:
•
Changing the Operating Parameters of a Fileset on page 5-14
•
Changing OSS File Caching for the Disks of a Fileset on page 5-16
Note. A fileset cannot be stopped until every fileset mounted on it is stopped.
