Important assumption!!!
|
|
the system is all used by one filer.
|
|
|
|
This command works this way:
|
|
1. collect all file ids from all volumes, as set A
|
|
2. collect all file ids from the filer, as set B
|
|
3. find out the set A subtract B
|
|
|
|
If -findMissingChunksInFiler is enabled, this works
|
|
in a reverse way:
|
|
1. collect all file ids from all volumes, as set A
|
|
2. collect all file ids from the filer, as set B
|
|
3. find out the set B subtract A
