Disk Quota Policy
To prevent storage misuse and problems resulting from filesystems becoming full, INCD has implemented the following data usage policies and limits.
|File system||Hard Limit Exceeded|
|/home||Once quota or number of files exceeded, new files will not be allowed. No automatic warning implemented. This may lead to login problems.|
|/data/unixgrp||Once quota or number of files exceeded, new files will not be allowed and all jobs will fail. No automatic checks implement and users are allowed to submit jobs and run then even no quota available.|
- There are two conventions for defining digital storage capacities, namely, base 2 (1KB = 1024 bytes) and base 10 (1KB = 1000 bytes), and both are in common use. At INCD we follow Base 2, the following definitions are used when referring to digital storage capacities (filesystem quota limits, usage, etc.):
|1 KiloByte (KB)||2 ^ 10||1024 bytes|
|1 MegaByte (MB)||2 ^ 20||1048576 bytes|
|1 GigaByte (GB)||2 ^ 30||1073741824 bytes|
|1 TeraByte (TB)||2 ^ 40||1099511627776 bytes|
|1 PetaByte (PB)||2 ^ 50||1125899906842624 byte|

NOTE Users should check in advance if they have enough quota for their jobs since this may lead to job failures and loss of CPU hours pledged to them.
