Hi John,
Enjoy your vacation š You are right, in that version of ONTAP 5% was default aggregate snap reserve, but it was already set to 0 at creation š
I did find a pair of FAS3270 which I think will take over from the FAS3240, and allow us to add more disks to the aggregatesā¦ Itās not a nice solution, but it is a solution where we do not have to move a lot of data aroundā¦ š

What about the aggregate reserve on the destination aggregates? I think it defaults to 5% (I could check on my existing 7-mode 8.1.3 system... but I'm on vacation. :-)
That might be enough space to get things rolling again.
Heino> All volumes are set to 0 in fractional reserveā¦ so thatās not it š

Heino> Check fractional reserve. That can use up space.

Heino> Hi there
Heino> We have two systems that mirror eachothers volumes via snapmirror.
Heino> We are talking 7mode ONTAP 8.1.4
Heino> The two systems have the same controller: FAS3240
Heino> They have the same disks and aggregate configuration (70TB aggregates)
Heino> On the source side we use volumes that are thin-provisioned with LUNs that have space reservation Heino> enabled, the LUNs are mostly close to 16TB (which is max)
Heino> All volumes are snapmirrored to volumes on the destination system with the same size and placed on Heino> the same aggregates that mirror the source aggregates in sizeā¦
Heino> The aggregates on the source are all below 95% used.
Heino> Yet.. we are now at the situation where a few destination aggregates are 100% full, while the Heino> source aggregates are still under 95% usedā¦
Heino> I have checked almost everything, like aggregate snapshot reserves etc.. but they should be the Heino> sameā¦
Heino> Can anyone explain why this can happen?
Heino> We are of cause at a ādeadlockā now.. I donāt think we can add anymore disks to the aggregates as Heino> they are max sizeā¦
Heino> The only think I can think of is either delete a volume from the affected aggregates, and re-sync Heino> the volume and hope it doesnāt fill up againā¦
Heino> Another way would be to add disks and build a new aggregate, and move some of the volumesā¦
Heino> Is there something I have missed? š
