Hi.
This week Grenville just increased my disk quota from 1GB to 10GB, but I’m still having problems with `Disk quota exceeded`.
I’m using `lfs quota -u lrpedro /work/n02` to check my quota in `/work/n02/n02/lrpedro`, but I’m suspecting now that the problem is on `/home/n02/n02/lrpedro`. However, I don’t know how to check the quota for `home` (and I thought there was just one quota and `home` was just linking files from `work`.
Can you help me figure out how to fix this problem?
Kind regards, Luciana.

Hi Luciana,
Yes it is indeed the `/home` quota that is exceeded. The `/home` disk is small so quotas are small for `/home`. All data files should be stored on the `/work` disk. I have increased your quota a little, however, I see you have a lot of netcdf files on `/home` which is causing your issue. I would suggest moving them to `/work`.
Regards,
Ros.

For some reason, I answered this thread directly from my email, but the messages weren’t addressed and they are not here. So I’ll just copy them here.
**Visit Topic or reply to this email to respond.**
This was in the previous email, so that’s what I’ve done. If this function doesn’t work, this line shouldn’t be in the emails.

Dear Ros.
Can you tell me what is the quota for home and how I check it?
Kind regards,
Luciana.

Dear Ros.
I’m trying to delete the netcdf files but I’m not sure how to do it all at once. I’ve tried **find** **. -type f -name ‘\*.o’ -delete** , but in ARCHER2 this command is not working recursively. And even after deleting some files manually, the usage in SAFE is not being updated. It would be nice to know how to sort this out.
Kind regards,
Luciana.

Hi Ros.
Another weird problem.
lrpedro@uan01:~/netcdf-files\> git add -A; git commit -m “files”; git push
fatal: failed to read from ‘u-bo026-n96-t2-files/atmos\_ens5/.nfs8034a08a000d49400000023d’: Device or resource busy

This week has been tough. 😕
Cordially, Luciana.

Hi Luciana,
Just looking in the logs I can see your emails were rejected as there is something wrong with the to: field. I will investigate. Sorry about that. This was working for someone else last week ok. The system logs tell me it sent you rejection emails, maybe worth checking your spam folder to check those did get to you.
> Can you tell me what is the quota for home and how I check it?
You can see your ARCHER2 disk quotas through SAFE. The usage is not updated instantaneously but updated periodically throughout the day. I’m not sure what the quota command is for the `/home`. I just tend use `du` and look in SAFE to see what my quota is.

This works on A2 fine for me
```auto
ARCHER2-ex> find testdir -name "*.o" -type f
testdir/file.o
testdir/anotherdir/file.o
ARCHER2-ex> find testdir -name "*.o" -type f -delete
ARCHER2-ex> find testdir -name "*.o" -type f
ARCHER2-ex>
```

> rm: cannot remove ‘.nfs8034a08a000d49400000023d’: Device or resource busy
This is a known issue. See the [ARCHER2 website for the solution](https://docs.archer2.ac.uk/faq/#undeleteable-file-nfsxxxxxxxxxxx). If, by any chance, this doesn’t resolve the problem you will need to contact the ARCHER2 helpdesk to resolve it for you.

Ros.

Hi Luciana,
Further to the email replying issue. I confirm the system is working as expected, I’ve just tried it out. I notice that you are responding from your gmail account and not the one registered with your Discourse account. I suspect that either Discourse is confused because it knows nothing about your gmail account or the email header is getting modified when forwarded from Reading to gmail. To eliminate the former, please try adding your gmail address to your Discourse account by logging in and going to your profile (top right circle → person icon) then preferences to view your settings then click “Add alternate email”.
Hopefully that will fix the problem.
Regards,
Ros.

Dear Ros.
I’ve added my gmail, so let’s see if that works now. Thank you for clarifying all my questions. 🙂
Kind regards,
Luciana.
