If psfsck locates errors that need to be repaired, it will display a message telling you to run the utility from the command line. For more information, see the HP Scalable NAS File Serving Software command reference guide or the psfsck(8) man page. CAUTION: We strongly recommend that you make a backup copy of the entire partition before you attempt to run psfsck with the --rebuild-tree option. The --rebuild-tree option should be used only if psfsck, when run in check mode, reports errors that can be fixed only by --rebuild-tree. If you run psfsck in read-only check mode, we strongly recommend that you run psfsck again without the --no-modify option. Other filesystem operations Configure atime updates PSFS filesystems can be configured to update access times (atimes) automatically when files are accessed in the filesystem. For a regular file, an "access" refers to reading the file. For a directory, an "access" refers to listing the contents of the directory. Because atime updates can have a performance impact, and to maintain the same behavior as in previous versions of the PSFS filesystem, the atime update feature is disabled by default. If needed, the feature can be enabled on specific nodes. A filesystem mounted on those nodes will perform atime updates unless the feature is disabled specifically for that filesystem at mount time. NOTE: Access times are never updated on read-only filesystems. Enable atime updates for a node To enable the atime update feature on a node, you will need to edit the /etc/opt/ hpcfs/mxinit.conf configuration file on that node. Add the following parameter to the file: psfs_atime_enabled = 1 HP Scalable NAS File Serving Software administration guide 151
