Snapshot Deletion - Ignore Owners

MohamedShehata

hello all,

when deleting a snapshot in CDOT we can use the variable [-ignore-owners], how can i use that in 7mode version [NetApp Release 8.2.3P6 7-Mode] ?

Hello,

i was actually able to view the LUNs i am looking for on the vfiler level [vfiler run VfilerName lun show] so i destroyed them and that solved the problem, much thanks for your response and support as usual 🙂

Hi,

What error message you are getting when you try to delete?

Also, you may follow the inductions listed in the below document:

Deleting busy Snapshot copies

MohamedShehata

i did actually follow this document because my snapshots are in busy state, but the issue is when i try to run the command [lun snap usage [-s] vol_name snap_name ] i get LUNs that are locking the deletion, when i try to destroy the LUN the systems shows that LUN doesn't exists, thats why i am asking if there is a way to ignore the snapshot owner in 7mode or maybe delete those LUNs somehow ?

Hi Mohamed Shehata,

When you compare the lun snap usage to the lun show output do you see the lun that you are trying to delete in "lun show"? The lun may already be deleted and you need to just delete the snapshot. Here is some additional information on deleting backing snapshot copies when a lun is deleted.

You can also reference KB: How to delete snapshots in the (busy,LUN) state

It sounds like there are some additional snapshots that might first need to be deleted before you can delete the original snapshot that is showing (busy, LUN). Let us know if turning on the snapshot_clone_dependency helps clear up the busy,LUN snapshot so it can be deleted.

Thanks

Hi darb0505,

I cannot see the lun when I use the command [lun show] and when I show the specific lun the output is [lun doesn't exists], I have deleted all the snapshots related to that volume except for the busy ones which cannot be deleted (the issue I am trying to solve) and I cannot find the option [snapshot_clone_dependency] on the system -> in advanced and regular mode I used the command [options] to view them all of them but I cannot find it.

Thanks...
