any reason not to rename an aggregate?
by Rue, Randy 09 Jul '20

09 Jul '20

We're changing our layouts and it would make functional sense to have a consistent naming scheme include an existing aggregate. Is there any impact from renaming an aggregate other than a new display name? Randy

Also watch out for the constituent member ( volumes under the covers ) count - I find the "default" is too high sometimes for the solution I am looking for.

fstab nfsv3 mount favorites?
by Scott Eno 07 Jul '20

07 Jul '20

Hi, It’s been a number of years since I worked in a Linux/NFS shop, so while I search for my old fstab mount options for a one-off project, does anyone have their go-to fstab nfsv3 mount options handy? The exported volume is on an ONTAP 9.6 cluster if it matters.

ONTAP Simulator
by Philbert Rupkins 06 Jul '20

06 Jul '20

Hello Toasters, Does NetApp provide the option to download old versions of the ONTAP Simulator? I'm looking for version 9.3 (any patch release) specifically but I am coming up empty. The oldest version of the simulator I see available is 9.5P6. I'm finding no links to older versions of the simulator anywhere on the support site. Cheers, Phil

Change Serial Number
by netapp_newbie 03 Jul '20

03 Jul '20

Hello, I bought old netapp but I have no license. I asked the guy who I bought he said this controller replaced in past but it should be licenses. I checked lots of doc , if controller replaced license should be generated by netapp but ı guess they forget to the that and now controller has no support and eoa. As a result ı have controller with no license. I have the old license keys but it locked with the old controller serial number. Is there anyway to change serial number. Because if ı can change serial number with old ones ı can use old license key. Thanks, -- Sent from: http://network-appliance-toasters.10978.n7.nabble.com/

Clone a volume & snapshots
by Chris Hague 30 Jun '20

30 Jun '20

Is there a way to make a clone of a DP volume and include its snapshots ? Attempted to use snapmirror with MirrorAllSnapshots but this only seems to include newer snapshots. Also tried vol clone create but that doesn't like the DP volume. Tested breaking the mirror so the volume becomes RW but a vol clone doesn't seem to include snapshots either. Thanks in advance.

single or multiple aggregates?
by Rue, Randy 30 Jun '20

30 Jun '20

Hello All, We're running a pair of FAS8020's with Flash Cache modules, SAS 600GB disks and DOT9.1P6 to serve two SVM's, one for an NFSv3 storage resource for our Xen VM farm and one for NFS/CIFS file storage for our users. We currently run one SVM on one node and one on the other to avoid any impact from mixing IO loads on the cache modules. We also have two aggregates, one for the VMs and one for the file server. We're getting tight on space and also getting tired of needing to withhold unallocated disks and hand them out as needed to each aggregate. Right now we have too much free space on one aggregate and not enough on the other. We're leaning toward using the system like an enterprise storage cluster is meant to be and migrating both to a single aggregate. On the other hand, we've been bitten before when mixing different performance loads on the same gear, admittedly that was for a larger pool of very different loads on SATA disks in a SAN behind a V-Series filer. We're not much worried about cache poisoning as long as we keep each SVM on each node. Our bigger concern is mixing loads at the actual disk IO level. Does anyone have any guidance? The total cluster is 144 600GB SAS 10K RPM disks and we'd be mixing Xen VMs and NFS/CIFS file services that tend to run heavy on "get attr" reads. Let us know your thoughts and if you need any more information, Randy in Seattle

turning on thin provisioning on an existing volume?
by Rue, Randy 29 Jun '20

29 Jun '20

Hi it's me again, A separate question related to our current woes. If I turn on thin provisioning on an existing volume will the unused space be merged/freed up/made available? Do I need to do anything to reclaim it? Or worst case, do I need to provision a new volume and migrate? Randy
