on Window servers, are there commands to tell the amount of data or blocks being changed? If so, I can then have an idea about how much space being produced by this VM for Snapshots space.   ... View more

@Ontapforrum  Just got the chance to reply. Thanks again for your help!   My only question left, should this OU name be already created in the new AD domain, before I run the following command? If yes, this OU name should be created by AD Admin, correct? cluster1::> vserver cifs modify -vserver vs1 -domain example.com -ou ou=example_ou -cifs-server example -status-admin down   ...

@Mjizzini    Thanks for your messages!   To replace currently AD Domain, why do I have to use  "vserver cifs create" , not  "vserver cifs modify"? Also, what should I do to keep the original cifs permission on the filer intact?   Please explain to me in details. ... View more

@Ontapforrum  You addressed my question. Thanks a lot for the bottom-up explanations. Now, I have a few follow-ups: 1. 'cifs setup" seems obsoleted, now the only way to have the vserver joined into AD domain is to use for instance "vserver active-directory create 'cmd'". Right?   2. If I wanted to migrate AD domain for this vserver to a different AD domain, then I can use "vserver active-directory modify -domain "new_ad.com". After that, the "old_ad" domain should be replaced.  Now, all permissions associated with old_domain would no longer work on the filer and NTFS level. I will have to manually change them to match new SID / new permissions. Then there will be down time. Correct?   3. Once AD domain got replaced, those NTFS permissions on CIFS shares will have to be changed on Window level, not on the filer level. Correct?   Hopefully,  I can continually hear your inputs.  Thanks! ... View more

I won't see anything? Why?   Based on this document as following, I should see information about AD account, this vserver joined.  https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.dot-cm-cmpr-960%2FTOC__vserver__active-directory.html   I am sorry, I didn't meant to ignore what you said, but I just don't understand.    How do I know which vserver is joined to which AD Domain then?   ...

I inherited the environment, so, didn't personally run "vserver active-directory create".    If the vserver didn't have an AD account, then why we can use AD permissions on CIFS shares? ... View more

Why it didn't list anything? that was my question. I got result "There are no entries matching your query.".   Shouldn't it list account infor on AD for that vserver as you said?   ... View more

2. I used a Linux server to mount and read data from SG several times, the average speed was 45MB/s. In your experience, is it normal performance speed I can get? 3. I have 4 nodes, and EC=2+1. What do you mean by highest possible EC schema? where can I check?   So, I am not sure of how much speed I should be able to achieve? ... View more

I am using the tiering policy to tier older data to Storagegrid. The performance to read data in SG is not that good, so, that is why I am  wondering if I can know in advance if the file or directory I am restoring is located in SG or Performance tiers, then to estimate how long the restoration may take.   i can guess based on minimum cooling days, but still because tiering is blocks based, so a file or directory may partially in one tiered, although much older data may have more chance being located in SG. Those are all my guess. I am wondering if there is way I can tell more acutely?   Thanks  for your input ! ... View more

Thanks for the correction!   Are there any official NetApp docs indicated the recommendation of changing the values to 128 in redhat 6.3+ even by default they are already set to dynamic?  ... View more

I would like to now ask you about slot tables. According to tr-3633,  both slot tables and max slot tables should be set to 128k, since the default 16k is too small. Obviously, this is only in the case of RedHat 6.3 or below. In 6.3+, the default value is 2, which means it will be dynamically adjusted according  to needs. It is not clear to me, should we still need to increase them to 128k in 6.3+? ... View more

Yes, you are correct again.   what about this one then? https://docs.oracle.com/en/database/oracle/oracle-database/19/cwlin/configuring-nfs-buffer-size-parameters-for-oracle-database.html#GUID-5F14F816-445B-4EBB-BBA2-E9DFD7E5EF96   It indicates 32k is recommended for oracle? ... View more

Well, in Oracle situation,  wsize and rsize should be set to 128k: https://www.netapp.com/us/media/tr-3633.pdf   So, upon Oracle recommendation, we should change the values to 128K on both NetApp and client side. Right? ... View more

Yes, you are correct. I have missed your point.    On NetApp, the setting is 64K. Does that mean I have to change it to 128K on NetApp first, in order to make 128K effect on Linux? And do I have to change all these three parameters to 128K?   Thank you! ... View more

There are no such settings on NetApp NFS vserver . wsize and rsize are only on Linux  ... View more

Thanks, but my question is about settings on NFS mount options on Linux, the server couldn’t recognize 131072 in /etc/fstab, and reduced the parameters down to 65536 as the actual mounting option.  Why?     ... View more

Thanks!   I am not asking how much space been used, but how much been written to the NFS volume during this period of the time? because there are a lot of overwritten data, and also they keep 1 month worth of data.    Again, my method can give us a rough idea? ... View more
