Question

How to disable quotas on an ext3 or ext4 filesystem?

Answer

Sometimes quotas will be enabled on a backup partition, which is not recommended due to potential performance issues.

1. You can confirm if quotas are enabled by checking the /etc/fstab file:

   # grep quota /etc/fstab
   UUID=08ec4d96-034e-4c3e-b199-9f3753de7171 / ext4 defaults,usrquota,grpquota 1 1

   Note: In the above, the output showing usrquota and grpquota indicates quotas are enabled. 

2. To disable quotas for a partition, open the /etc/fstab file using your preferred command-line file editing tool, such as vi or nano for example.
3. Remove the usrquota and grpquota entries.
4. Save and close the file.

5. Remount the partition:

   # mount -o remount $MOUNTPOINT

   Note: Replace $MOUNTPOINT with the partition you are remounting.
