| 3 | fs_flushmount - Forces the Cache Manager to discard a mount point | |
| 4 | ||

| 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. | |
| 35 | ||
| 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. | |

| 52 | ||
| 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. | |
