fs_flushmount - Forces the Cache Manager to discard a mount point
The fs flushmount
command removes from the cache all information
associated with each mount point named by the -path
argument. The next
time an application accesses the mount point, the Cache Manager fetches the
most current version of it from the File Server. Data cached from the
associated volume is not affected.
The command's intended use is to discard information about mount points that has
become corrupted in the cache. (The Cache Manager periodically refreshes
cached mount points, but the only other way to discard them immediately is to
reinitialize the Cache Manager by rebooting the machine.) Symptoms of a
corrupted mount point included garbled output from the fs lsmount
command, and failed attempts to change directory to or list the contents of a
To flush cached data rather than a mount point, use the fs flush
- -path <dir/file path>+
- Names each mount point to flush from the cache. Partial
pathnames are interpreted relative to the current working directory, which
is also the default value if this argument is omitted.
- Prints the online help for this command. All other valid
options are ignored.
The following command flushes from the cache the mount point for user
"pat"'s home directory:
% fs flushm /afs/abc.com/usr/pat
The issuer must have the "l" (lookup) permission on the ACL of the
root directory of the volume that houses the file or directory named by the
argument, and on the ACL of each directory that precedes it in
