Are filesystems and interfaces local to each filer, even when clustered? Or, when clustered, does each filer shares the filesystems?
Local to each filer.
Specifically, if I have filers A and B, and I run "df" and "ifconfig" against each filer:
Do they return the same outputs?
No.
Or, does each filer retain its identity when clustered? So, /vol/vol0 and all other filesystems on filer A is different than /vol/vol0 and all other filesystems on filer B?
Yes.
Does it matter what mode I am in? Takeover, Cf Disabled, etc?
After a takeover, the two filers still have independent identities. A single hardware head is pretending to be two different filers. To clients, it still looks like two separate filers.
So essentially, what I am asking is: Is each filesystem identifiable by it's Filer Serial number AND File system name? Or, by it's Cluster and File System name?
The filer and filesystem name uniquely identify the filesystem.
