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 … [View More]

pNFS not working on vserver when several lifs with different Vlans available
by Florian Schmid 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 … [View More]

Use X382A in DS224C on A200/A220
by Alexander Griesser 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. Thanks, Alexander Griesser … [View More]

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
