Aggregate percentage space filling up with Aggregate Space Full error
Applies to
- ONTAP 9
- All FAS/AFF models
- Non-FlexGroup and FlexGroup volumes
Issue
- When aggregate space is filling up, the following alert may be received:
critical event on Node1:Aggr_1 (Aggregate Space Full). The aggregate is 90.00% full (using 56.92 TiB of 63.24 TiB). There is an unknown amount of spare disk space available for expanding the aggregate.
- Volumes in the aggregate are also affected:
Message: monitor.volume.full: Aggregate "aggr_1" is full (using or reserving 98% of space and 0% of inodes).
Description: This message occurs when one or more file systems are full, typically indicating at least 98% full. The space usage is computed based on the active file system size and is computed by subtracting the value of the "Snapshot Reserve" field from the value of the "Used" field of the "volume show-space" command. Either a volume or an aggregate can be over 100% full due to space used or reserved by metadata. A value greater than 100% might cause Snapshot(TM) copy space to become unavailable or cause a volume to become logically overallocated. See the "vol.log.overalloc" EMS message for more information.
Corrective Action: Create space by increasing the volume or aggregate size, or by deleting data or deleting snapshot copies. To increase a volume's size, use the "volume size" command. To delete a volume's snapshot copies, use the "volume snapshot delete" command. To increase an aggregate's size, add disks using the "storage aggregate add-disks" command. Aggregate snapshot copies are automatically deleted when the aggregate is full.
