Hi there,
I'm trying to delete a LUN from Ontap 9.7. It throws an error as "ONTAP API Failed: Read-only file system". I tried from CLI with "-f" flag. Still getting the same error. Any idea how I can delete read-only LUN.
Regards,
Emadul
Solved! See The Solution
The hosting volume was sitting idle. I deleted the hosting volume and that took care of the LUNs that I was unable to delete.
Hello my friend,
What is the volume type where this LUN is hosted?
Which command did you use on CLI for the deletion attempt?
Regards,
Pedro
Hi Pedro,
I believe the volume type is “DP” and I used this command to delete “ lun delete -vserver SVM2 -path /vol/MX02_mirror/MX02_PUBFOLD -f”.

Here is the output from "lun show -vserver SVM2" command
I'm trying to delete the offline LUNs.
Hi,
Does the hosting volume have been or is in a mirror relationship? Type DP normally is a mirro destination...
If so, you could try to break any mirror relationship first and then try to delete things...
The hosting volume should RW
The hosting volume was sitting idle. I deleted the hosting volume and that took care of the LUNs that I was unable to delete.
