Clonfs1 is the main file server for the clon cluster. It holds /home, /local etc directories for all clon machines. It can be managed using link http://clonfs1/na_admin/. Its ''/etc'' directory and volumes are mounted on clon00 and clon10 under ''/mnt/admin''.

'''NOTE''': if exporting ''hostname'' is not registered officially (does not recognized by ''nslookup''), it must be described in clonfs1's ''/etc/hosts'' file !

'''NOTE''': after changing ''/etc/netgroup'' or ''/etc/exports'' (see below) do ''ssh root@clonfs1'' and execute command ''exportfs -a''. If not exported, try following trick: add some existing machine (clon10 for example) to the ''/etc/exports'' to all entries, and do ''exportfs -a''. Next time change clon10 to clon00, and so on.

Clonfs1 has following volumes:

'''apps (backup by CC)''' - contains machine-dependent packages not installed into /usr/local area

'''archives (backup by CC)''' - contains occupancy/recon plots and other files we want to preserve

'''clas (backup by CC)''' - contains clas-specific contents (''/usr/clas/parms'', ''/usr/clas/devel'' etc)

'''clonweb (backup by CC)''' - directory mounted on ''clonweb'' machine as ''/www''

'''clonwiki (backup by CC)''' - directory mounted on ''clonwiki'' machine as ''/wiki''

'''downloads (backup by CC)''' - contains various downloaded files

'''home (backup by CC)''' - contains home directories for all clon users

'''local (backup by CC)''' - contains machine-dependent /usr/local/bin, /usr/local/lib etc directories for various operating systems used on clon machines

'''logs''' - contains log files from various clon systems

'''mysql (backup by CC)''' - contains backups from mysql server machine(s)

'''scratch''' - scratch disk

'''work''' - work disk
