Disable quota

[JasperA]

I recently upgraded from 6.2.4 to 6.4.0

As I understand Disk Quotas are now supported.

That's nice, but I don't need it and what's more, it completly renders my NAS useless due to btrfs-cleaner taking up 100% of the CPU.

I let the btrfs-cleaner finish it's work, but it restarted locking up my ReadyNAS 516 the next day completely.

I really would like to be able to turn off disk quotas completely, or disable btrfs-cleaner if that's a better option.

Can anybody tell me how to do this; the NAS is useless since my upgrade to 6.4.0.

Hi,

Your quota check probably takes a long time because of a certain level of file system fragmentation you have.

Can you download your logs and post the Metadata line from your btrfs.log?

I think this is what you meant:

Metadata, DUP: total=279.00GiB, used=21.98GiB
Metadata, single: total=8.00MiB, used=0.00B

I tried to disable quota using the 'btrfs quota disable /data' command, repeated this for all mount points... So probably quota is off now (the command didn't give me any output at all). After this, I only saw btrfs-cleaner for a short period of time this morning (enough to kill my NAS), but after that only kworker was really busy (doing what??) and my NAS was responsive enough not to kill my NFS service. I'm curious for what will happen tonight, but probably the NAS (and services) will survive this time.

And guess what?

It didn't survive. This morning btrfs-cleaner was busy, busy, busy, busy. Rendering my NAS completely useless again, stopping servicing NFS and killing all my VM's.

This device has become completely worthless to me.
