Deleting no longer required datasets

[NugentS]

I am trying to delete some datasets that are no longer required.
I have removed snapshots
I have removed the NFS Share
There is no SMB Share
Nothing is using these datasets any longer

When I try to delete the dataset I get dataset is busy. This happens a lot

Any thoughts?

lsof | grep <dataset>

any chance there is a live ssh connection to the box sat in that dir?

Not that I am aware of.

 

[NugentS]

lsof | grep <dataset>

Produces a large number of lines all of which are multiple versions of:

Code:

lsof: no pwd entry for UID 201
lsof: no pwd entry for UID 65535

That's to be expected if you run jails. No output for open files on that dataset?

 

[NugentS]

No Jails - this is Scale. There are No apps using the dataset

The warnings about missing UIDs can come from apps as well. Inside the container something is running with UID X that the TN host does not know. That's why lsof complains. Can be ignored. Again: no files in the lsof output?

No files. Well no files pointing at /mnt/AppPool/Docker/"insert name of dataset" or just the dataset. They all point at VM's on different pools or /usr

ooo - though you have just made me think of something which shouldn't have an effect - but might have some sort of hangover. I have deleted the NFS Shares to the folders, but a VM which had them mounted is still running

And...... Nope - still can't delete

I rebooted the NAS and was allowed (briefly) to delete some of the datasets - but after 30 seconds or so got the dataset is busy again. I managed to delete 3 datasets

 

[Johnny Fartpants]

Could you change permissions to break any legacy access and then try and delete?

Do you have a terminal or ssh session open and are IN that directory? That one has caught me a few times.

 

[NugentS]

I didn't.
I did eventually manage to delete the datasets - but had to reboot to do so
