Filesystems available to user on whiteout
Different filesystems are available for different purposes.
/u/$username – users home files with quota. Used for irreproducible data (like source code). Is stored on drizzle using DMF.
/scratch/$username – short term storage for fast data access. A local scratch filesystem for temporary working space - you can create files in /scratch/$username but should not leave anything in here once you're finished working with it. Currently this filesystem is around 5T in size.
There is a direct gigabyte ethernet link between Drizzle and Whiteout, to improve performance of NFS mounted filesystems between these two hosts.
What is DMF?
DMF is a hierarchical file storage system and allows you to overallocate diskspace by transparently moving files to tape when not used. There may be slight delays between requesting a file and actually using it.
Current there exist DMF client tools such as dmls, dmget, dmput, etc to display the status of your files.
Secure Copy (scp)
Secure copy is part of the ssh package and allows you to securely copy files from one machine to another. It is very similar to the 'cp' command, encrypts transfered data and allows you to recursively send all the files in a directory.
The first argument is the file to copy and the second is the location to copy the file to. You can copy from one local location to another remote location, or even transfer files from one remote location to another. Use the '-r' argument to copy all files in a directory.
Eg: scp mylocalfile.txt username@remotehost:/some/path
eg: scp massdata.csv nsonneve@whiteout.sf.utas.edu.au:~/massstorage
eg: scp bob@whiteout.sf.utas.edu.au:/short/bob/blah.txt ~
eg: scp user@remote1:/test.txt user@remote2:~
There exists a windows utilitity called WinSCP that allows you to do the same graphically. Available from here
FTP is not available.
