SQUID users can move data between your local environment and the storage on SQUID through the web I/F through the use of Nextcloud. The data stored via Nextcloud is on

/sqfs/home/[UserID]/OnionWeb/ and so you can access it on the frontend and compute nodes of SQUID.
example: If userID is "user001", your data stored on /sqfs/home/user001/OnionWeb/

 

How to link the work area

In the initial state, only the area under the Onionweb directory is visible. By creating a symbolic link to the work area, etc. in the Onionweb directory using the following procedure, you can find the area on ONION-file via the link file.

cd ~/Onionweb
ln -s /sqfs2/cmc/[0 or 1]/work/[Group name]/[UserID]/ work
example: If userID is "user001",group name is "G00001": /sqfs2/cmc/0/work/G00001/user001/

†The value of [0 or 1] depends on the group.

Note) Currently, it takes approximately 30 minutes to reflect the file/directory creation on SQUID to Nextcloud. We are working hard on the investigation for shortening the time. The file/directory transfer to SQUID through Nextcloud is refrected without time gap.
We are sorry in advance for this.
