Our site has about 800 UNIX systems, each NFS-mounting ~10 directories from our NetApp (an F760 running ONTAP 5.3.4) via the automounter. Does managing all these mounts critically impact the filer?
The reason I ask is that if I have an automounter map with the following indirect mount entries:
framemaker -rw,nosuid,intr,hard nassrv:/app_vol/framemaker netscape -rw,nosuid,intr,hard nassrv:/app_vol/netscape proe -rw,nosuid,intr,hard nassrv:/app_vol/proe metaflo -rw,nosuid,intr,hard nassrv:/app_vol/metaflo (etc...)
Then would changing these to
framemaker -rw,nosuid,intr,hard nassrv:/app_vol:framemaker netscape -rw,nosuid,intr,hard nassrv:/app_vol:netscape proe -rw,nosuid,intr,hard nassrv:/app_vol:proe metaflo -rw,nosuid,intr,hard nassrv:/app_vol:metaflo (etc...)
(which is supposed to reduce the number of mounts from the NetApp) provide significant improvement in performance on the NetApp? Would this significantly lower the load on the NetApp? Our UNIX systems are such that they do not reboot often, although I am unable to quantify how many mount requests to the filer occur in, say, an hour.
