Why central storage?
As a research institute, we certainly hope the following two things:
1. All data are easily accessible by all the members, particularly for computing purpose. 2. All data are safe, at least for those that are important.
We then start up the central storage system, which is based on the cluster and can be accessed in a straightforward way on the cluster per se. If you wish to access this storage from windows, you have to install an NFS client or use sftp. The most important data are protected by overnight backup.
Storage Configuration
The current configuration involves the following storage blocks:
/nfs/disk/perm: the entry for all data and toolkits, weekly backup
/nfs/disk/work: the entry for home direcotry and group work, overnight backup
/nfs/asrhome : asr space, NO backup
/nfs/sidhome : speaker group space, NO backup
/nfs/nlphome : NLP group space, NO backup
/nfs/corpus : databases, linked to /nfs/disk/perm, weekly backup
/nfs/project : project space, linked to /nfs/disk/work/project, overnight backup
/nfs/public : public usage(demo, web, cvs etc), linked to /nfs/disk/work/public, overnight backup
IMPORTANT: Since asrhome/sidhome/nlphome are not backed up (at least for now), please use them carefully. The important data should be put under /nfs/disk/work/[asr/sid/nlp].
User and group quota
The space on /nfs/disk/work is valuable, so I will set some quota constraints for each user home dir under /nfs/disk/work/users, as well as the group dir /nfs/disk/work/[asr,sid,nlp]. Please use these backup space for the important things and leaving others to the group home dir (asrhome/sidhome/nlphome). You can also use the /nfs/project to obtain overnight backup, but this should be only so if the project is worthy to do so.
The user allocation is 10GB, while the group space quota is 200GB. Let me know if you have special requests.
Restore your files
In any case that you want to recove your files (either by disk failure or unwilling deleting), just logon grid-1 and then copy from /mirrordisk
For admin
1. The backup crond scripts are in on grid-0 /mirrordisk/utl, the crontab is in /etc/cron.d 2. The quota uses quota-tools.
