Silly question, but in your 'vol move' command, are you using the constituent volume as the volume to move (e.g. the vol__001) and not the actual flexgroup name?

Encrypting Flexgroup vols with NAE
by Scott Eno 20 Nov '21

20 Nov '21

Hi, I had to move flexgroup vols from NSE disks to NAE aggrs once, so I know I knew how to do this then, but for the life of me I can't find it written down anywhere. Basically, how does one do a "vol move start ... -encrypt-with-aggr-key" for a flexgroup with constituents on all four aggrs in the cluster (two on each node)? TR-4571 (Hi Justin!) seems to say this is possible, tho the doc it links to doesn't explain how to do this with a flexgroup. cse

Security Descriptor noob question
by Carl Howell 25 Oct '21

25 Oct '21

I have a test volume with a CIFS share and default permissions. If I want to modify the NTFS permissions using either vserver security file-directory ntfs modify...or something like Ansible, how do I find the security descriptor to modify(ntfs-sd): vserver security file-directory show -vserver svm1 -path /test4 -instance Vserver: svm1 File Path: /test4 File Inode Number: 64 Security Style: ntfs Effective Style: ntfs DOS Attributes: 10 DOS Attributes in Text: ----D--- Expanded Dos Attributes: - UNIX User Id: 0 UNIX Group Id: 0 UNIX Mode Bits: 777 UNIX Mode Bits in Text: rwxrwxrwx ACLs: NTFS Security Descriptor Control:0x8004 Owner:BUILTIN\Administrators Group:BUILTIN\Administrators DACL - ACEs ALLOW-Everyone-0x1f01ff ALLOW-Everyone-0x10000000-OI|CI|IO Feel like I'm missing something obvious here. . .

Tech Refresh Path for MetroCluster
by Heino Walther 14 Oct '21

14 Oct '21

Hi there We are in the process of quoting a tech-refresh of our two node Stretched MetroCluster (A8080 nodes, one at each DC) We were initially looking at a Ethernet based MetroCluster replacement, yet because of Cisco’s horrific back lock, we are more or less forced to choose another Stretched MetroCluster at the replacement. The question is if there is a recommended upgrade path for this? In a standard HA setup we normally just add the new two nodes into the existing cluster, and move volumes and LIFs… pretty easy and with no down time. But it is a bit different with a two node MC mainly because it is essentially two single node clusters. If we were to add another two nods into the existing cluster, we would also require four FC switches in order to link up the FCVI cards which is currently linked up back-to-back between the two DCs. So I see two possible ways… Headswap… from A8080 to A400 (should be possible with any down time? Just switchover, replace node, recable, reassign disks, switchback, then add new shelfs, and move volumes…) ? Parallel setup and move workloads from one to the other… (most is vmware, so not that big a deal… but there are also some critical iSCSI LUNs which will require more work) One other little possible issue is that the old cluster has a 6G Disk Loop and a 12G Disk Loop… both use the QSFP/MiniSASHD to Optical… but the old 6G loop cannot work with the A400 because to my knowledge it does not have any supported PCIe card that has QSFP connectors? (not according to HWU). But we do have four 6500N ATTO Bridges that we can use for this… so right now the plan would be the following: Introduce the ATTO 6500N bridges into the existing solution (there are plenty of fibers across the two DCs) Switchover node 1 to node 2 Headswap node 1 to A400, and recable. Reassign old node 1 disks to new node 1 Switchback node 1 (same procedure on node 2) Attach new disks to both nodes. Create new root aggr0 on new disks for both nodes (move configuration to new aggr0… (described somewhere…) Move volumes to new disks. Remove old empty aggregates and unassign Remove physical disks Any other suggestions? And have anyone else tried this? I think I read somewhere that it was actually not possible to expand a two node MC to four nodes… is that really correct? /Heino

Distribution Function & Jumbo Frames
by Carl Howell 06 Oct '21

06 Oct '21

I've got a four node cluster where each node has a 10Gb ifgrp connected to LACP port-channels on Nexus 9k's. Each of the ifgrp's has its distribution function set to ip. My first question is, should I tear these ifgrp's down to change their distribution functions to port? Next, all of these port-channels and ifgrp's have MTU 1500. I'd like to of course set them to 9000. The process to do this I believe is to raise the MTU on the port-channels to 9216. Raise the MTU on the ifgrp's to 9000, and then raise the MTU's on the Broadcast domains to 9000. My question is, can I do this without an outage? I've tested this on another cluster, but it unfortunately doesn't have ESXi(NFS), Oracle(NFS), SQL Server(iSCSi) clients on it. There seems to be a small outage when the ifgrp is changed, but I can't determine if that will cause any issues on the client side. Thanks as always for the help. --Carl

Upgrade from 9.3 to 9.7
by Philbert Rupkins 21 Sep '21

21 Sep '21

Hello Toasters, Anybody have experience, positive or negative, upgrading from 9.3 to 9.7? It is a supported automated upgrade path but requires packages for both 9.5 and 9.7. My understanding is each node will be upgraded twice (once to 9.5 then to 9.7) but otherwise should follow the typical automated upgrade routine. Thank You Phil

create a flexclone of the snapshot, mount that lun to any windows server and double click on the vhdx file, it will open/mount as a drive letter.

Hyper-V file recovery from snapshot
by Jeff Cleverley 01 Sep '21

01 Sep '21

Greetings, I'm trying to figure out how to mount a .vhdx (Server 2012 Hyper-V/Failover Cluster) to be able to view or restore a specific file. I have only found 2 ways to do this so far: 1. Copy the .vhdx from the snapshot to the physical server and mount it. 2. Use Disk manager and mount it read-only remotely from the NetApp. I have found this is only working if the VM was down when the snapshot was taken. Is there a way to get the .vhdx from the snapshot mounted remotely? When I have to copy a 300G .vhdx, it is very slow and it limits the systems with enough free space as targets. I was hoping to use this as opposed to having to apply one of our various traditional backup methods. Thanks, Jeff -- ** Please note my email address has changed to jeff.cleverley(a)broadcom.com Jeff Cleverley Factory Systems Engineer 4380 Ziegler Road Building 1, Dock 1 Fort Collins, Colorado 80525 970-288-4611 -- This electronic communication and the information and any files transmitted with it, or attached to it, are confidential and are intended solely for the use of the individual or entity to whom it is addressed and may contain information that is confidential, legally privileged, protected by privacy laws, or otherwise restricted from disclosure to anyone else.

options for adding a shelf/disks to an AFF-A220
by Rue, Randy 01 Sep '21

01 Sep '21

Hi All, I've cabled up the second external shelf for our AFF-A220 and it sees the disks. Now I'm at a fork in the road. We currently have two local data tiers made up of 24 disks each, one on each node. Best practices at https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-ps… say a disk group of SSDs should be from 20-28 SSDs each. If I go to create a new local tier the default is to create two new tiers, one on each node. That would give me two disks groups of 12, below the best practice. How badly would performance suffer? Any other caveats? Reliability? I could put them all on one disk group, and on one node? Bleah. I could add half of them to each existing tier/disk group and exceed the best practice by eight SSDs. I believe I've seen discussions (get it?) claiming that top limit is flexible with SSDs, was it here? But when I add another shelf I'll have the same problem. Seems like the clearest path forward for consistency and future expansions is to add two tiers with small disk groups. So, can anyone guess if I'll have a significant performance impact? Any other caveats? Grateful for any guidance, Randy in Seattle
