Hi Srijan,
Is there a way of getting the status of the crawl process?
We are going to expand this cluster, adding 12 new bricks (around 500TB) and we rely heavily on the quota feature to control the space usage for each project. It's been running since Saturday (nothing changed) and unsure if it's going to finish tomorrow or in weeks.
Thank you!

Hi João,Yes it'll take some time given the file system size as it has to change the xattrs in each level and then crawl upwards.stat is done by the script itself so the crawl is initiated.

I think you've already looked into the blog post by Hari and are using the script to fix the accounting issue.That should help you out in fixing this issue.Let me know if you face any issues while using it.Regards,Srijan SivakumarOn Fri 14 Aug, 2020, 17:10 João Baúto, <joao.bauto@xxxxxxxxxxxxxxxxxxxxxxx> wrote:Hi Strahil,I have tried removing the quota for that specific directory and setting it again but it didn't work (maybe it has to be a quota disable and enable in the volume options).

Based on your output it seems that the quota size is different on the 2 bricks.
Have you tried to remove the quota and then recreate it ? Maybe it will be the easiest way to fix it.
Best Regards,
Strahil Nikolov
