I would respectfully disagree. pNFS does not stripe data across controllers. Data is distributed, not striped. Every node is a metadata server and will redirect the client process to the node directly holding the volume. No striping. Maybe you are confusing pNFS with FlexGroups which distributes files across nodes. A very long time ago in ONTAP GX, there >>was<< an ability to stripe data across controllers. That feature was removed upon going to ONTAP 8.0 --tmac *Tim McCarthy, **Principal Consultant* *Proud Member of the #NetAppATeam <https://twitter.com/NetAppATeam>* *I Blog at TMACsRack <https://tmacsrack.wordpress.com/>* On Mon, Aug 16, 2021 at 9:36 AM Michael Bergman via Toasters < toasters(a)teaparty.net> wrote: > > > > ---------- Forwarded message ---------- > From: Michael Bergman <michael.bergman(a)ericsson.com> > To: Toasters <toasters(a)teaparty.net> > Cc: > Bcc: > Date: Mon, 16 Aug 2021 13:34:17 +0000 > Subject: Re: pNFS not working on vserver when several lifs with different > Vlans available > On 2021-08-16 15:13, Florian Schmid wrote: > > Is this really the case?

Re: pNFS not working on vserver when several lifs with different Vlans available

That's how pNFS is supposed to work. That's the whole point one can say, of pNFS. It's striping of the data traffic (not metadata) across several nodes, all at once. In that respect, the setup you say you have, this: "On the vServer, we have several different Vlans and each Vlans has an interface for each node there. Our storage network is completely switched, so no routing between Vlans possible." is totally wrong for pNFS. In such a set up you definitely do not want pNFS. /M

pNFS not working on vserver when several lifs with different Vlans available
by Florian Schmid 16 Aug '21

16 Aug '21

Hi, I had a very strange incident some weeks ago. We are on 9.7 branch. In one of our vServers, where we had NFSv4 and 4.1 enabled, clients with NFSv4.1 and pNFS where unable to read or write data. Directory listing was possible. On the vServer, we have several different Vlans and each Vlans has an interface for each node there. Our storage network is completely switched, so no routing between Vlans possible. After creating a NetApp case, they told me, that pNFS doesn't handle Vlans and the client will get any IP on that node, even when the IP is from a different Vlan and therefor not accessible from the client. Is this really the case? Is the pNFS process really not Vlan aware and sends any IP from that node where volume is located, even when the IP is in a different network than the client IP? As suggested from NetApp, I have disabled pNFS and now everything is working. What is your experience here? Is anybody using pNFS with NetApp and if yes, do you only have one network in your vServer or is the client able to access all IPs there through different Vlans? I'm curious about your answers. Best regards Florian Schmid

Use X382A in DS224C on A200/A220
by Alexander Griesser 16 Aug '21

16 Aug '21

Hey there, Does anyone know if it's safe to use the X382A SSDs from C190 storages in A200/A220 storages in DS224C shelves? HWU is giving me mixed information (or I'm reading it wrong), DS2242C seems to be supported for this SKU but when you check for platform compatibility, only the C190 is listed (for whatever reason). The reason I'm asking is that I could get a few oft hem but they're too small for my use cases, but the SSDs could be useful in other environments.

Removing .snapshot from directory listings?
by Fenn, Michael 04 Aug '21

04 Aug '21

Does anyone know if there's a way to hide .snapshot in directory listings, but have it still be accessible if you know the name? This is how .zfs/snapshot works, and it's an (IMHO) elegant way to make snapshots accessible without having a naïve find, du, etc. at the root of the filesystem descend into deep snapshot hierarchies. Note that I do see the snapdir-access field on volumes, but setting that to false seems to block access to .snapshot completely, which isn't what I want. Thanks, Michael

adding a shelf to an AFF220
by Rue, Randy 22 Jul '21

22 Jul '21

Hi All, We have an AFF220 with one external shelf and are adding a second shelf. I see clear info in the NetApp docs on how to connect multiple shelves, daisy chaining the shelves and returning the last shelf to the head. But the docs are based on setting up a new system and I haven't found anything on adding a shelf to a new system. Do I just move that return cable to the new shelf? Will there be any interruption to services? What else do I need to know? Thanks, Randy in Seattle

space reporting on AFF's with compression?
by Rue, Randy 22 Jul '21

22 Jul '21

Hello All, We're migrating from a FAS to a new AFF that has inline compression and a guarantee of 3X compression. I'm trying to convert a graphite/snmp graphing system that reports our overall aggregate space usage to the new system. A straightforward graph of used and free space on the data aggregates/tiers shows the right portion of space used but seems to be reporting pre-compression usage (and we appear to be getting less than 3X). The System Manager webUI says we're getting ~120:1 "Data Reduction" but it also says we're using 1.74PB and have 14TB available. In fact we currently have 48 x 900GB SSDs in two disk groups/tiers and about 40TB of actual unstructured data. Is there a doc somewhere on understanding space reporting with the new system including meaningful reporting of compression returns? Grateful for any help, Randy in Seattle
