Hey folks, Does anyone here enable rquota on NFS on CDOT? If so, does it allow modifications to quotas? Cheers! Basil

It's labeled "confidential" so you'd have to go ask your NTAP rep I guess. It's called Performance Considerations NetApp Volume Encryption Real world, well it isn't really that per se. But absolutely real in the sense that it was a proper test. Performance benchmarks run w/ and w/o NAE & NVE for AFF (8080 & 8040). For FAS I do not think there is anything and spinning disk is a problem in so many was anyway that you probably better stay away from NVE/NAE there. It will just become even more unpredictable for you than it already is to to speak. Not sure why you write "NAE for AFF" but "NVE for FAS". For FAS I'd recommend NSE disk --> no impact. > > VMWare running on NFS, CIFS, FCP > > All filers running within acceptable CPU \ DISK UTIL. (50% and under). Is > there a latency penalty? By this you probably mean that both CPU and Disk util are well under <50% "everywhere". VMware running on... could mean anything. That notion doesn't say anything really. What the workload is depends on what the VM's are doing of course. The general A is that yes there is a latency penalty but YMMV. It's quite possible that *you* in your use case would not notice any such heightened latency. It all depends on how hard you push the system overall. There's a IOPS vs Latency curve of course, there always is. NVE/NAE will move this curve compared to w/o encryption. Exactly how depends on your particular workload pattern.

Console/ssh hangs when starting snapmirror
by Douglas Siggins 26 Nov '19

26 Nov '19

Greetings, This is FAS8080 running 8.2.5P37Mode, and we've seen it on 3 of the same systems that are newly installed (it is for a migration to cmode). Wondering if anyone has run into this issue. We are experiencing an odd issue where when starting a snapmirror of serial/SP the console hangs (messages do appear on the screen). If we ssh into the system it works fine. If we drop and go back to console it is still hung. We've also tested starting the snapmirror via ssh and that hangs as well, and the console works fine. I havent confirmed whether or not if I then drop that SSH session and relogin if it is still hung. I've never seen this before on new systems, and wondering if anyone has seen the exact issue. I have however seen consoles/ssh hang because of system load or wafl checks, but never with establishing a snapmirror baseline. Regards, Douglas

Encryption at rest

Can anyone give me some real world performance expectations for enabling encryption at rest? NAE for AFF NVE for FAS VMWare running on NFS, CIFS, FCP All filers running within acceptable CPU \ DISK UTIL. (50% and under). Is there a latency penalty? Chris. p.s.

Volume move.... Working?
by Scott Classen 05 Nov '19

05 Nov '19

Hello toasters, I’m attempting to move a 3TB vol to a new aggregate. The destination aggregate has 100TB available space. It’s been preparing to transfer for over 3 hours…. Is this normal? Cluster::> volume move show -vserver svm1 -volume bigvol Vserver Name: svm1 Volume Name: bigvol Actual Completion Time: - Bytes Remaining: - Destination Aggregate: cluster_03_sata01_8t Detailed Status: Volume move job preparing transfer Error: Creating Snapshot copy with owner tag: Not enough space for Snapshot tags Estimated Time of Completion: - Managing Node: node-03 Percentage Complete: - Move Phase: replicating Estimated Remaining Duration: - Replication Throughput: - Duration of Move: 03:21:53 Source Aggregate: cluster_03_sata02_8t Start Time of Move: Mon Nov 04 09:10:19 2019 Move State: warning Is Source Volume Encrypted: false Encryption Key ID of Source Volume: Is Destination Volume Encrypted: false Encryption Key ID of Destination Volume: Should I be concerned about the "Error: Creating Snapshot copy with owner tag: Not enough space for Snapshot tags” ? Is there any way to see if this vol move job is hung or actually doing something? Thanks, Scott

FabricPools
by John Stoffel 05 Oct '19

05 Oct '19

Hi all, Has anyone got good dirt on the strengths and weaknesses of FabricPools? We're looking into a refresh where we have tons of old stale data, and FabricPools hooked upto a DataGrid block storage might be a good way to get a decent setup. Not sure, and I'm sure there are gotchas we need to look out for. But anyone have good/bad experiences? We're looking to consolidate about 400T on two 7-mode pairs (3250s and 3220s) into one new setup. Not sure which way we should go... John

volume statistics
by Mike Thompson 04 Oct '19

04 Oct '19

Back in the day, I used to be able to run: statistics show -vserver ${vserver} -object volume -raw true -counter read_ops|write_ops|other_ops|read_data|write_data and get back counters of total reads/writes/etc going back to either when the filer was last booted, or the volume was moved from one filer to another. looks like nowadays in ontap9 you are supposed to turn on statistics collection for some period of time, then stop it, and then inspect that collection run. which is great and all, but all I want is the total number of reads or writes to a volume, not for a specific period of time, but overall. are these basic counters buried somewhere still in ontap9?

Hyper-V and MetroCluster
by Jeff Cleverley 20 Sep '19

20 Sep '19

Greetings, The short question is: Is there any way to manage Hyper-V between clusters in a MC configuration without the VMs crashing? We have seen KBs saying the Witness and persistent file handles can only be moved between cluster nodes. We have a MC configuration that was running 9.1P17 and upgraded it to 9.3P14 during a downtime. We also had to physically move one half of the MC during this downtime. We have a Hyper-V cluster running Server 2012R2, SMB 3.0, and CIFS file systems housing the VMs set as continuously available. During the downtime, most, but not all VM went down hard when switched to the other half of the MC, and also when switching back. It appears linux VMs housed on the same cluster/SVM that were moved did not object to the disruption and did not reboot. Since the VM disk space went away when cluster1 was switched to cluster2, the clients had no access to disk space, and we have no event logs. We assume they paniced and rebooted. The Hyper-V clients failed immediately as the switchover was started. Are there any types of timeout settings that can be configured for the VMs so they just pause during this and pick up again when the SVMs start up on the other half of the MC? If the problem is with CIFS, we would be open to iscsi or SAN storage if it would allow them to survive a MC switchover.

Adding Flash Pool - Error
by Christopher D. Chandler 16 Sep '19

16 Sep '19

We are trying to increase our Flash Pool to an existing aggregate and getting the following error message: Data ONTAP API Failed: Cannot add capacity from storage pool "DHIP10NTAP02_SSD" to aggregate "aggr01_DHIP10NTAP01_02", because the currently allocated capacity to the aggregate does not span across all disks belonging to the storage pool. Grow the aggregate before allocating more capacity from this storage pool. (Error: 13001) The aggregate is 69.21 TB in size and has 185.93 GB of cache per a Storage Pool already allocated. Chris

Migrating from VSC on VC 6.5 to VC 6.7
by Christopher D. Chandler 16 Sep '19

16 Sep '19

I have Virtual Storage Console running on our VMWare 6.5 environment and we would like to migrate to VMWare 6.7. I have a FAS6290 with OnTap 9.1. I am unable to find a license to support Snap Manager running VSC as the new dedicated appliance. Any help is appreciated. Chris
