configuration backup is very large and contains netboot

tom_dewit

Hi all,

 

I noticed that on one node of a cluster (Ontap 9.7), the system configuration backup was much larger than on others (1.5Gb instead of the normal 50Mb on the other nodes). I see that the complete netboot directory is contained in this backup (1.4Gb in size). How can I exclude this directory from the configuratioon backup or can I even just delete it in the root volume ?

 

Every time the configuration backup is taken, I get slow CP warnings for my root aggregate, so I would like to ease the stress by shrinking the config backup.

There used to be a KB describing this I think, but it seems to have disappeared. It was called  'How to find what is filling a node's root volume'

 

Thanks is advance

 

Grtz,

Tom

I don't have access to that link

I was able to solve it myself by deleting the netboot directory from systemshell. However, I would like this KB to be accessible again as this problem is not so uncommon.

There are diagnostic level commands that are not to be performed without NetApp guidance. We will see what we can do however to make it possible or some process.

Hi Paul,

 

I understand that NetApp would want to shield those articles from customers, but they should be accessible to SSC/ASP NetApp partners (and they were accessible in the past)

Fixed.

Thanks Paul. One suggestion: Could you add an extra bullet point that if a netboot folder is present under /mroot/etc that this folder can be safely deleted in the root volume ? That was what was causing my cluster configuration backups to be huge.

Good point. I added a note to step 5. Let me know if that works.

Not to split hairs, but it would be easier to add it as a numbered point like where you are deleting trace files in point 3. We would be deleting the whole netboot folder if it exists and not just a large file that would happen to be in that folder (that is where you have put the note now).

 

But thanks for the clarification ... it would at least have helped me solve this issue more quickly.

hello tom,

 

im curious about how a netboot directory ended up in /etc.

 

  • do you have the full path?  or can you provide the serial number?( if Autosupports are on i can check)
  • adding a note to look for netboot dir might be rare since it may be a one -off for this case.

we will review the KBs we have and clean them up.

 

fyi we also have this kb better suited for config backups failures - https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/Cluster_configuration_backup_creation_failed

though in your case it was not failing , you just noticed a size diff compared to the other nodes. would need to create something new for this scenario.

We appreciate the Feedback

Logan,

 

It may be more interesting to make a separate article for that problem and link to that in both the current KB's. I actually think an article may already have existed for that or it still does, but I don't have access to it. The netboot folder impacts both sizes.

 

The controller I had removed this netboot directory on was sysID 0538175320. It was recently headswapped to a FAS8300 and netbooted at that time, so that may explain something about how it ended up being there.

 

It may be rare, but not that rare, as I am sure about at least 3 times that I had this issue including this one..

The node shell rm command doesn't remove directories, just individual files. Hence why I put in step 5.

To remove the directory you need to use ‘rm -rf’
