Metadata Utilities: nsck and sync
Synchronizing Metadata with Actual Files
5-22 CLI Maintenance Guide
Synchronizing with Actual Directories
Some installations require new directories that cannot be configured through the
client interfaces. These directories have features that can only be added through an
administrative interface on the back-end filer itself, such as disk quotas. If such a
directory is created behind a managed volume, you can use the sync utility to add it to
the metadata. This can only function for empty directories, and for directories that are
only on a single share behind the managed volume. From priv-exec mode, use the
sync directories
command to search a managed-volume directory for any new,
unrecorded subdirectories:
sync directories namespace volume vol-path path path
where:
namespace (1-30 characters) is the namespace to sync. Use the
show
namespace
command for a list of configured namespaces (see “Listing All
Namespaces” on page 7-3 of the CLI Storage-Management Guide ).
vol-path (1-1024 characters) chooses a specific managed volume in the
namespace. Use forward slashes (/) in the path, even for CIFS volumes.
path (1-1024 characters) selects a virtual path in the volume (for example, ‘/’
or ‘/home/jrandom’). The sync utility searches for new directories under this
path; it only searches this directory, and does not descend into any known or
discovered subdirectories.
Like the nsck and sync-files operations, this generates a report as it runs. The report
name appears after you issue the command.
For example, this command sequence synchronizes the root directory in the
medarcv~/lab_equipment volume and then shows the report:
bstnA6k(gbl)# end
bstnA6k# sync directories medarcv volume /lab_equipment path /
Scheduling sync directories operation on switch bstnA6k, report name:
sync.5._lab_equipment.rpt
This utility is not supported in multi-protocol (NFS and CIFS) namespaces.
