In the following example, the cache is deleted, then re-created, and then mounted again with the demandconst option specified for the file system /docs. This example shows the steps including rebooting to single user mode. You may have other commands you prefer to use to accomplish some of the tasks shown in this example.
$ su password: # shutdown -g30 -y . . . Type Cntrl-d to proceed with normal startup, (or give root password for system maintenance): # enter password: . . . Here is where you may be prompted from system to run fsck on the file system where the cache is located. # fsck /local # mount /local # cfsadmin -d all /local/mycache # cfsadmin -c /local/mycache # init 6 . . . console login: password: # mount -F cachefs -o backfstype=nfs,cachedir=/local/cache1, demandconst merlin:/docs /docs # |
If you did not successfully remount the file system in the cache, the system displays an error message similar to the following:
cachefsstat: /doc: not a cachefs mount point |
