File systems available

  • The users have at there disposal three types of filesystem:

    • A common NFS filesystem for homes not shared with workernodes

    • A lustre filesystem for some groups shared filesystem with the workernodes

    • A CVMFS read-only filesystem for software provision

  • Groups involved in WLCG transfer data using grid technologies can also use the Tier-3 storage areas and dedicated software areas (CVMFS) made available by there communities.

Access Policy

  • By default both lustre and nfs individual group areas can be accessed (read only) by users of the same group.

Directories and filesystems

The pauli machines provide a wide set of filesystems so that users can access their data and applications.

NFS Home directories

Users home mounts are not shared with workernodes, they can be found only on submission nodes: 

FILESYSTEM            MOUNTED ON            SCOPE
se63:/user            /user                 LIP groups

NFS Data directories

CVMFS Software provision

The CVMFS is a read-only filesystem with cache local to clients optimal for software provision: 

FILESYSTEM            MOUNTED ON            SCOPE
cvmfs2                /cvmfs/cms.cern.ch    CMS VO

cvmfs2                /cvmfs/sw.el7         LIP

Important Disclaimer

  • Manipulating huge sets of small files generates performance degradation issues in /lustre due to the lock management. Therefore, you should not

    • Compile anything under /lustre

    • Store and access databases under /lustre

Access your data by SSHFS

Install sshfs package

On Ubuntu/debian: 

# sudo apt-get install sshfs

On RHEL/CentOS/Fedora: 

# sudo yum install fuse-sshfs

Create a local directory

# mkdir ~/homeNCG

Mount your remote folder

# sshfs martinsj@fermi.ncg.ingrid.pt: ~/homeNCG

When you're done, you can unmount it

# fusermount -u ~/homeNCG

.bashrc tunning

In case you're dealing with very long paths, as a suggestion, you can add to your ~/.bashrc file the following: 

alias mfermi='f(){ dir=$1 ; [ -n "$dir" ] || dir=homeNCG ; [ -d ~/$dir ] || mkdir -p ~/$dir ; sshfs fermi.ncg.ingrid.pt: ~/$dir ;  unset -f f; }; f'
alias ufermi='f(){ dir=$1 ; [ -n "$dir" ] || dir=homeNCG ; [ -d ~/$dir ] && fusermount -u ~/$dir ; [ -d ~/$dir ] && rmdir ~/$dir ;  unset -f f; }; f'

alias mncg='f(){ dir=$1 ; [ -n "$dir" ] && ldir=`basename $dir` ; [ -d ~/$ldir ] || mkdir -p ~/$ldir ; [ -n "$dir$ldir" ] && sshfs fermi.ncg.ingrid.pt:$dir ~/$ldir ;  unset -f f; }; f'
alias uncg='f(){ dir=$1 ; [ -n "$dir" ] && ldir=`basename $dir` ; ldir=`echo $ldir ; [ -d ~/$ldir ] && fusermount -u ~/$ldir ; [ -d ~/$ldir ] && rmdir ~/$ldir ;  unset -f f; }; f'

alias mcalo='f(){ [ -d lcalo ] || mkdir ~/lcalo ; sshfs fermi.ncg.ingrid.pt:/lstore/calo ~/lcalo ;  unset -f f; }; f'
alias ucalo='f(){ [ -d ~/lcalo ] && fusermount -u ~/lcalo ; [ -d ~/$ldir ] && rmdir ~/lcalo ;  unset -f f; }; f'

This is how you can use it: 

$ mfermi homeNCG
$ df
