With the new ZFS(?) file system IT is using for work disks, quotas have two categories:
- Guaranteed space
- Maximum space
Currently our space is at 2.7 TB guaranteed and 5.0 TB maximum.
What does this mean?
The space on the raid is either:
- assigned to a particular partition (call this assigned space)
- or designated as shared among all partitions (call this shared space)
- or not available to any parition (call this un-assigned)
When a partition goes beyond it assigned space, it can use the shared space as long as the partition stays below its maximum and as long as there is shared space available to use.
How do you know how much space is available?
The standard df command shows available space as the maximum, unless there is not enough shared spaced to allow going to the maximum. Then it shows the appropriately limited total. So that means
- the available space on a partition can change
- it can change due to the activity of other users on the raid
