Disk quotas

Disk quotas #

Individual disk usage quotas are enforced on disks /data4t and /data14t. You can use the following command to query your current usage and quota statistics

quota -s

The output will look like this:

Disk quotas for user danilov (uid 1002): 
     Filesystem  blocks   quota   limit   grace   files   quota   limit   grace
      /dev/sda3   2422M   2560M   3072M           40587       0       0        

There are two types of limits:

  • the total size of used disk space in kilobytes (blocks);
  • the total number of files (files).

There are no limitations on the maximum number of files. The command quota will show you the current usage for blocks/files, as well as the value of quota and the maximum limit. Zeros in both quota and limit fields are used as unlimited values. The operating system will not allow the user to exceed the limit value, returning the error similar to Disk quota exceeded. However the user may exceed the quota value for a limited time (7 days). In this case the remaining time will be present in the field grace.

Individual disk usage quotas for /data4t and /data14t are currently disabled.

Disk /data90t #

This disk is shared by three groups: users, geosci, and biomath. The total size of each group is limited. There are no individual limits for users in each group. You can use df command to get the size of available space in each group, e.g.

df -h /data90t/users/

The output will look like this:

Filesystem      Size  Used Avail Use% Mounted on
/dev/sdc1        15T   10T  5.1T  67% /data90t
