linux group

SoLID Linux group is "12gev_solid"

check your account groups by command "groups"

Please ask Seamus Riordan <riordan at jlab.org> to add your jlab account to the group if you want to use SoLID related computing resource at jlab.

Batch Farm Project

jobs should go to the 'solid' project

Disk Space

We have disk space on the CUE

/volatile/halla/solid (short temp)	3 TB
/work/halla/solid (long term)	1TB
/mss/halla/solid (permanent, on tape)	10 TB

The volatile guaranteed reservation is 500GB and files there are expected to have an expiration date of six months. Please use /volatile for larger data sets and /work for sources and reduced datasets you need to keep. You must belong to the group 12gev_solid for access, ask "Ole at jlab.org" to add you.

To avoid disk quota problems, please make sure that all files that you place in the SoLID directories are owned by Linux group 12gev_solid. If you've already created files that have the wrong group, just change the group ID of your directory and all its files and subdirectories to the correct one. You only should have to do this once:

chgrp -R 12gev_solid your-directory

To make this happen automatically for all newly created files in this directory, set the sgid bit on it:

chmod g+s your-directory

Better yet, set this bit for all subdirectories as well:

find your-directory -type d -exec chmod g+s {} \;

Again, you should only have to do this once.

Additionally, to reduce the chance of file access problems, every time you log in and before starting work in SoLID disk areas, switch your effective group ID to 12gev_solid:

newgrp 12gev_solid

Exit from the shell when done; that will return you to where you were before issuing the newgrp command.
