17 | =head1 DESCRIPTION | |
18 | ||
19 | The B<fs flushmount> command removes from the cache all information | |
20 | associated with each mount point named by the B<-path> argument. The next | |
21 | time an application accesses the mount point, the Cache Manager fetches | |
22 | the most current version of it from the File Server. Data cached from the | |
23 | associated volume is not affected. | |
24 | ||
25 | The command's intended use is to discard information about mount points | |
26 | that has become corrupted in the cache. (The Cache Manager periodically | |
27 | refreshes cached mount points, but the only other way to discard them | |
28 | immediately is to reinitialize the Cache Manager by rebooting the | |
29 | machine.) Symptoms of a corrupted mount point included garbled output from | |
30 | the B<fs lsmount> command, and failed attempts to change directory to or | |
31 | list the contents of a mount point. | |
32 | ||
33 | To flush cached data rather than a mount point, use the B<fs flush> or | |
34 | B<fs flushvolume> command. | |

36 | =head1 OPTIONS | |
37 | ||
38 | =over 4 | |
39 | ||
40 | =item B<-path> <I<dir/file path>>+ | |
41 | ||
42 | Names each mount point to flush from the cache. Partial pathnames are | |
43 | interpreted relative to the current working directory, which is also the | |
44 | default value if this argument is omitted. | |
45 | ||
46 | =item B<-help> | |
47 | ||
48 | Prints the online help for this command. All other valid options are | |
49 | ignored. | |

53 | =head1 EXAMPLES | |
54 | ||
55 | The following command flushes from the cache the mount point for user | |
56 | C<pat>'s home directory: | |
57 | ||
58 | % fs flushm /afs/example.com/usr/pat | |
59 | ||
60 | =head1 PRIVILEGE REQUIRED | |
61 | ||
62 | The issuer must have the C<l> (lookup) permission on the ACL of the root | |
63 | directory of the volume that houses the file or directory named by the | |
64 | B<-path> argument, and on the ACL of each directory that precedes it in | |
65 | the pathname. | |
