No free space in aggr0


Hi Community,

We don´t have available space in our system (FAS2050 ONTAP 7.3.3), but there are space available in vols. We do not understand this situation and gets warnings:

sis.aggregate.full:warning]: Aggregate aggr0 is full Change logging metafile on SIS volumes in the aggregate can not hold any more fingerprint entries.

Re: No free space in aggr0


The space of the volumes is reserved in the aggregate.

If corrreo and volumes are file shares accessed through CIFS or NFS you could reduce the volume size on the fly through System Manager or FilerView

Another possibility would be to change the space reservation of the volumes to none so that the free space on the volumes is given back to the aggregate.

Don't touch vol0 as it is the DataOntap OS volume.

Re: No free space in aggr0


Thanks Mathieu,

but the output of "df" is bigger than "aggregate allocated" and the space use in vols does not match the aggregate space usage.

if that space is no data in snapshots of the vols, where is it?
Thank you

Re: No free space in aggr0


In 7.3.x the ASIS fingerprints for the FlexVols are stored in the aggregate.  You're  aggr is full so ASIS can no longer update the fingerprint DB.

You can either reduce your FlexVols or my recommendation, remove your aggr snap reserve

snap sched -A aggr0 0 0 0

snap reserve -A aggr0 0

This will free up 57GB and allow ASIS to continue.

Re: No free space in aggr0


Spence thank you for your help

The only way is grow the space?  or adding disk to aggr0 or resize vols or space reserve?

is difficult to assume, because there is space available at the level of vols

Re: No free space in aggr0


Please go to and read the Data ONTAP 7.3.3 manuals.

In the mean time if you want to get ASIS to work and stop warning you then:

snap reserve -A aggr0 0

snap sched -A aggr0 0 0 0

If you want to thin provision your FlexVols then:

vol options correo guarantee none

vol options unixusers guarantee none
