Quotas | HPC @ LLNL

Quotas Defined

Users get default quotas on various file systems at LC. This is the amount of space and number of inodes that can be put on the specific file system by the user. Once the user hits their quota, they won't be able to write any more data until they remove some data.

Quotas for File Systems

The table below shows how much quota you get on the various file systems by default. If you need more than the default, you can request it via the instructions below. Remember that Tier 2 and Tier 3 are file system AND Zone specific. This means that if you request Tier 2 to get that bump to 75TB/25M on /p/lustre1 on the CZ, that is the only place you get it. If you need Tier 2 on /p/lustre2 on the CZ, that is a second request. Please make each request separately so that it can be directed to the appropriate authorizer.

To see how much quota you have used;

Log onto a slic machine (CZ - oslic, RZ - rzslic, SCF - cslic)
type "quota"
- shows you your utilization of the various file systems mounted in that particular zone (CZ/RZ/SCF)

Quotas for Storage

Storage is LC's tape archive system where users can store data for later. For more info on the tape archive - go to https://hpc-staging.llnl.gov/documentation/tutorials/livermore-computin…

To see how much quota you have used,

Log onto a slic machine (CZ - oslic, RZ - rzslic, SCF - cslic)
type "knit"
- you will be prompted for your username and password - that is your RSA or RZ token and pin
- gives you the required kerberos credentials
type "aquota"
- your prompt will change to "aq>"
- puts you in the command line storage quota tool application
type "show quota"
- tells you how much quota you currently have
type "exit"
- returns you back to your normal prompt

^†these quotas are per directory, not per user as in all other cases

^†^†NOTE for quotas with a "/", the second number equals inode limits in M (million) number increments where appropriate.
