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
.
Disk quotas for user danilov (uid 1002):
Filesystem blocks quota limit grace files quota limit grace
/dev/sda3 2637M* 2560M 3072M 7days 40588 0 0
The quotas for both disks /data4t and /data14t are set individually for each user. If you exceed the quota you will receive the warning message on your login. If you need to enlarge your quota, please contact Alexander Danilov, INM RAS, room 629, a.a.danilov@gmail.com.
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
