UNMAP space issue
by Heino Walther 07 Jul '21

07 Jul '21

Hi there We have an old 7-mode NetApp on which we have created several 16TB LUNs and presented them via FC to a Windows host on which we have created one large drive using StoragePools. We now have the issue that space is not unmapped on the NetApp as we delete files from out large drive… SnapDrive does not see the LUNs we have mapped because StoragePools uses them, so we cannot start the Space Reclaimer. We have tried sdelete.exe with the -z option, but it does not seem to work for us… I have read that we should be able to use defrag /L or Optimize-Volume X -ReTrim -SlabConsolidate But I was wondering if anyone has tested this? The StoragePool was created on Windows 2016, but has since been moved to a Windows 2019 platform.. Any suggestions are very welcome 😊 We are talking very large volumes, so I would rather not test that much 😉 /Heino

10GbE to 40GbE Upgrade
by Carl Howell 15 Jun '21

15 Jun '21

We currently have an A300 cluster, each node has 2x10GbE interfaces in a multimode_lacp ifgrp connected to 2xCisco 9K's. We are upgrading each node with 2x40GbE interfaces. The question is how best to go about doing the upgrade? It would of course be nice if we could just add the 40GbE interfaces to the current port channels and ifgrp's, but I don't think the 9K's will allow us to mix speeds in a port channel. Perhaps it's possible on the 9K side to set the new interfaces to 10GbE, add them to the ifgrp's and port channels, drop the original 10GbE interfaces out and raise the speed on the new interfaces up to 40GbE. . . Thanks in advance for any help. --Carl

So far it has been very good to me. I am having my air-gapped customers move to this. We avoided 9.8-9.8P2. P3 came out but was quickly followed by P4. --tmac *Tim McCarthy, **Principal Consultant* *Proud Member of the #NetAppATeam <https://twitter.com/NetAppATeam>* On Mon, Jun 14, 2021 at 12:16 PM Brian Parent via Toasters < toasters(a)teaparty.net> wrote: > > > > ---------- Forwarded message ---------- > From: Brian Parent <bparent(a)ucsd.edu> > To: toasters(a)teaparty.net > Cc: > Bcc: > Date: Mon, 14 Jun 2021 09:12:03 -0700 > Subject: 9.7P12 vs. 9.8P4 ?? > We're at 9.7P12 now.

9.7P12 vs. 9.8P4 ??
by Brian Parent 14 Jun '21

14 Jun '21

We're at 9.7P12 now. I've got a day or two to decide whether to jump to 9.8P4, and stay there. Our AFF8020 apparently isn't qualified for 9.9RC1. I'm retiring in two weeks, and the crew I'm leaving behind (sorry, not sorry), doesn't have experience upgrading NetApps. They plan to leave it as is until they can decommission it in 6-12 months. It seems like a good idea to move to 9.8P4 due to the openSSL bug fixes. Any horror stories about 9.8P4?

Expanding Raid groups to grow an aggregate
by Fred Grieco 25 May '21

25 May '21

Toasters, I am setting up a new A400 that came with 3.5 disk shelves (3 shelves with 24 disks and one shelf with 12 disks), for a total of 84 disks. Setting the partitioning bit aside (I think I have that right..), I configured raid group sizes of 20, two groups each into two aggregates, one on each controller. This uses 2 x 2 x 20 or 80 disks and leaves 2 spare disks on each controller, which are actually 4 partitions per side spread out on the SSDs. There will be an issue if we order SSDs to fill the half shelf. There would be no way to add these disks to the existing aggregates and not have really lopsides RG sizes. But if I expanded each of these raid groups by 2 or 3 disks and added the new disks manually, it would work out great. Is this the best practice for adding disks? Wouldn't that scheme leave data "stranded" on the existing disks? Does this matter even with SSDs in light of the performance per disk. Thanks, Fred

We have 2node FAS2520 (no switches). How to migrate SVMs to a new cluster? Want to preserve CIFS server names and IP addresses. Last time we used 7MTT to do the migrations.. is there similar tool for cluster mode migrations? br, sk
