Metadata Utilities: nsck and sync

The Namespace-Check (

nsck

) and synchronization (

sync

) utilities manipulate the

metadata in managed volumes.

Metadata

is high-level information such as

physical-file locations on back-end filers, modification-time stamps, and file sizes.
The nsck utility can show a volume’s metadata to reveal which back-end shares hold
its files and directories. If you suspect that the metadata is inconsistent with the
back-end files, you can use nsck to re-examine the filers and compare the results with
the metadata. Wherever nsck finds metadata inconsistencies, you have the
opportunity to correct them.

The nsck and sync utilities offer several options for working with metadata:

•

nsck

report

shows the current state of metadata,

•

sync finds and corrects metadata inconsistencies,

•

nsck

rebuild

rebuilds an entire namespace by re-importing all of its shares,

•

nsck

destage

removes all metadata for a volume, share, or filer so that you can

directly access the filer(s), and

•

nsck

migrate

moves a volume’s metadata from one back-end share to another.

The nsck and sync utilities do not apply to direct volumes, which contain no
metadata. This chapter is relevant to managed volumes only.
