Thanks for your messages, very helpful. This is a large VM's environment (+2000), all based on NFS datastores, which can benieft from NFS's advantages, easy to provision etc. HCI/SolidFire change the datastore infrastructure to iSCSI based, how can I know it will be better than NFS, and particularly in performance perspective in such dynamic workload enrioment, oracle, SQL, NFS and CIFS?

netappmagic · ‎2020-11-20

I have very basic knowledge about Solidfire, and one of thing it is lack of as I know is NFS. I have two questitons: 1. What is alternative to NFS if we implement Solidfire. 2. For FAS storage cluster, and a lot of VMware VM's, what is the general procedure to migrate all data over? Thanks!

netappmagic · ‎2020-11-20

Can somebody please share your experience on using these two monitoring tools? any pros and cons? Is there general sense of which one is better? Thanks!

netappmagic · ‎2020-11-05

yes, single cluster.

I am talking about SP connections to other nodes, and these nodes are A300, and A700 as well. Only these two AFF nodes timeout is short

netappmagic · ‎2020-11-05

A700 SP ssh session, how do I reset the timeout parameter? Any other nodes are fine, only these two A700's, and cluster ssh session is fine as well. Thanks!

I had to set unix-permission to 777 on NetApp side, in order to touch a file with ownership of "nfsnobody nogroup", otherwise, it won't allow me to touch and got "permission denied". Can somebody please confirm , do I have to set to 777? if yes, then anybody can do anything but root, that sounds not good.

@AlexDawson , In our case, we added the new 24x890GB SSD for increasing the required root volume size, but didn't partition them as you suggested we should. As it is now, I am interested in two options that you pointed out, and would like you to weigh in which one I should go for. 1. With total of 18x890GB, creating a new aggr on a node would cause two nodes in HA out of balance, personally, I prabably would not prefer. 2. Adding 9x890GB to each node into the existing aggr as a new rg, AND deducting two disk as parities, that would probably add 6TB more in each aggr, assuming the size mismatching is alright, is it worth doing it? I am going to send you 2 serial numbers for these two new heads. Due to issues here with sending out on-demand Autosupport, you might not be able to see the updates, but there is a manually trigged one there. Thanks a lot for your time.

It is running cluster mode 9.6p7, and the shelf was added due to swap heads to A700's for increase root volumes required by the A700's. In the root aggr, rg0 is still using inherited R-D partition from old heads, but rg1 is using 3 new and entire 890GB disk's. If we should not store user data on root aggr, why not? we will then left total of 16TB unused. Thanks!

netappmagic · ‎2020-10-04

We have a shelf with 24x890GB SSD disks. Currently, 2x3 of them have been assigned to 2 root aggrs respectively to two nodes in HA. then left total of 2x9x890G = 16TB physical space. How should we use the 16TB space? creating separate aggregate seems too small. I If I add 8TB into the root aggregate, and create a separated volume for data, would that cause any potential issues? Thanks you!

Hi, Thanks for your message. But, this seems not what I am asking for. With SM solution, we have to license CVO. With CV, no cvo license required. So, if we don't have to use SM, then we prefer CV Cloud Volume is transferring backup data on the file level versus Snapmirror is on the block level. For the purpose of transferring the backup data to AWS from on-prem, do we have to use SM&CVO?

netappmagic · ‎2020-09-23

I need to upload Oracle RMAN backup data on-prem to AWS, I have two options: using Cloud Volume via NFS or implement Cloud Volume OnTap and then use SnapMirror. The difference between these two methods is, CV transfers data on file level, and the SM transfers data on block level. Here is my question: Since RMAN backup data is static data, do I have to transfer data on the block level? either method should be fine, in my opinion. What would you think, and why?

netappmagic · ‎2020-09-05

by setting the permission to 777 on the volume, I got both Example 1 and Example 2 work on page 117. Please ignore my last two messages above. Sorry for confusing. However, I don't quite understand what we are trying to do here. Here, "root" is squashed to nfsnobody (65534). But, what if I also want to have the "root" to do what "root" is supposed to do on this NFS file system. What am I missing ?

netappmagic · ‎2020-09-05

I have done same steps as instructed in page 117, however, I (either as root or an user) could not "touch" any files or do anything on the mounted NFS file system, got "permission denied" error. Can experts here please help me out ?

netappmagic · ‎2020-09-04

Following Example on page 117 of this document https://www.netapp.com/us/media/tr-4067.pdf, I am not able to touch any files on this NFS file system. Please find the screenshot on errors, and also the Example on page 117 excerpted below. Could you please point out what went wrong? On my local Linux server, 65534 is corresponding to "nfsnobody" in /etc/passwd file. Could it be the cause, if yes, why could it be the cause?

I don’t seethe expected trusts domain by running the command below. Is this due to only one way relationship not two, or no any trusts created at all? I was told trust is already created. So, I am confused. ::> cifs domain trusts show Thank you!

netappmagic · ‎2020-08-17

I wanted to add Domain B as the trusted domain for Domain A? What steps do I have to go through? 1. Create two way trust in Domain A and then Domain B first in Active Directory Domain, right? 2. Use the following command to create the trust on Cluster: vserver cifs domain name-mapping-search add -vserver vserver_name -trusted-domains FQDN , ... 3. What is the right command to verify? 4. Is there any commands to show if this is one-way or two-way on Cluster, or have to be on AD? Please help in details. Thank you!

netappmagic · ‎2020-08-12

I am understanding better now. But to help me further: The user quota can also limit the capacity for users, in addition to track the usage, right? Can I use tree quota to limit the user's capacity as well.

netappmagic · ‎2020-08-12

What is the method to tell how many IOPs a SSD aggr can provide?

netappmagic · ‎2020-08-12

Your messages helped. - Can I then say that the quota with tree type is not for the case if I wanted to put a disk limit on users, and tree type is for the case if I waned to put a limit for an application? - Can I use tree type to limit space for users? - In following example, target is empty, which means essentially not limiting any users, just a quota and not being applied to any users, or is it a default quota for all other user not being fall into any other quota policy? cluster1::> volume quota policy rule create -vserver vs0 -policy-name default -volume FG -type user -target "" -qtree "" -disk-limit 1T -soft-disk-limit 800G Thank you!

netappmagic · ‎2020-08-12

I didn't have the link. Although it is talking about quota on FlexGroup, I guess it would apply to Flex Volume as well. cluster1::> quota policy rule create -vserver vs0 -policy-name default -volume FG -type tree -target tree_4118314302 -qtree "" -disk-limit 48GB -soft-disk-limit 30GB So, for this particular example, - what this "tree type" command can do, but the other "user type" command cannot do? - what is "tree_4118314302"? is this an unix user id? - it is using tree type, but with -qtree "", does that mean this quota is not using qtree? Thanks for your patience.

netappmagic · ‎2020-08-12

Yeah, I had already read the link before I post the question. Unfortunately, I still don't understand. In real cases, why do we need to have the tree type of quota if already have the user type ? or vise versa?

netappmagic · ‎2020-08-11

Quota type can be Tree or User. My question is, when should I use Tree type and when use User type? Why do we have have to have these two different type? I guess, fundamentally, I don't understand how these two type of quotas work. Thanks

netappmagic · ‎2020-07-26

Hi, What is your solution? I have exactly the same issue. "ansible 192.168.191.18 -i filers -m ping" is not working neither. /bin/sh is not recognized command, that is the error when I use "-vvv" option. Thanks,
