1.4.4.2.3. Accessing the grid storage system using GFAL

You can now access our grid storage system at

• davs://bohr3226.tier2.hep.manchester.ac.uk:443//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/, or

• root://bohr3226.tier2.hep.manchester.ac.uk:1094//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/.

Warning

Notice the double slash in ...ac.uk:...//dpm/.... If a single slash is used, some tools might fail.

For example, to see what’s inside,

gfal-ls -alH --full-time davs://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/
# or
gfal-ls -alH --full-time root://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/

And to make a directory there,

gfal-mkdir davs://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/testing
# or
gfal-mkdir root://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/testing

To delete it,

gfal-rm -r davs://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/testing
# or
gfal-rm -r root://bohr3226.tier2.hep.manchester.ac.uk//dpm/tier2.hep.manchester.ac.uk/home/souk.ac.uk/testing

Note

We omitted the port when gfal is used here, as the default ports are used.

Warning

You can delete files created by others, vice versa. Thing twice before deleting or overwriting. To protect your files, you may use gfal-chmod below.
