Notes
- The notation /x/{y|z} stands for /x/y or /x/z
- Sizes are indicative, since we adjust them as needed
- the notation 1.8/2.0TB means that the soft limit is 1.8TB and the hard limit is 2.0TB of disk space
- the notation 4/5M means that the soft limit is 4 million
inodes
and the hard limit is 5 millions - Snapshots allow to restore deleted files, up to that many weeks
- Public space under
/pool
and/scratch
is scrubbed weekly - files older than 180 days are removed.
2. Storage Efficiency
- It is inefficient to store a slew of small files and if you do you may reach your
inodes
quota before your space quota (too many small files).- Some of the disk monitoring tools show the
inode
usage. - If your
%(inode)>%(space)
your disk usage is inefficient,
consider archiving your files intozip
ortar-compressed
sets.
- Some of the disk monitoring tools show the
- While some of the tool(s) you use may force you to be inefficient while jobs are running, you should remember to
- remove useless files when jobs have completed,
- compress files that can benefit from compression (with
gzip
,bzip2
orcompress
), and - archive a slew of files into a
zip
or atar-compressed set
, as follows:% zip archive.zip dir/
or% tar -czf archive.tgz dir/
both examples archive the content of the directorydir/
into asingle zi
p or atgz
file. You can then delete the content ofdir/
with% rm -rf dir/
- You can unpack each type of archive with
% unzip archive.zip
or% tar xf archive.tgz
3. Scrubbing of Public Disks
- We have implement a FIFO (first in first out) scrubbing model, where old files are deleted, aka scrubbed, to keep free space on the public disks.
- There is an age limit, meaning that only files older than 180 days get deleted.
- Older files get deleted before the newer ones (FIFO),
- We run a scrubber on a weekly basis.
- Consult the Scrubber and How to Request Scrubbed Files to be Restored page for additional information.
- In any case, we ask you to remove from
/pool
and/scratch
files that you do not need for active jobs.
4. Dedicated Project Disk Space
- For projects that would benefit from dedicated disk space, such space can be secured with project's specific funds when we expand the disk farm (contact us).
