Clonfs1

Clonfs1 is the main file server for the clon cluster. It holds /home, /local etc directories for all clon machines.

To manage, 'ssh root@clonfs1' and do following:

• to export partitions: 'exportfs -a'

• to increase volume size on 50G: vol size <volume_name> +50g

• to check if partition is actually exported to particular machine, go to that machine or any other machine and type:

DO NOT KNOW HOW ...

• if partition exported but machines has problem mounting it, use following example where machine '129.57.167.184' could not mount:

exportfs -c 129.57.167.184 /vol/logs
   exportfs: 129.57.167.184 does not have mount access to /vol/logs (Access denied)
exportfs -f /vol/logs
exportfs -c 129.57.167.184 /vol/logs
   exportfs: 129.57.167.184 has mount access to /vol/logs

• use 'help' to see all commands

OBSOLETE: 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)

clas12 (backup by CC) - contains clas12-specific contents (parms, coda 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
