I've added the SRU Bug Template. Could you take it from here?
** Description changed:
+ [Impact]
+
+ * Dovecot users using the fs quota plugin see wrong quota calculation
+ (overquota situation)
+
+ * LTS version is affected. Bug would remain for a long time.
+
+ * Patch is simple (1 line)
+
+ [Test Case]
+
+ * Prerequisite: user quota configured on filesystem where dovecot stores
your
+ email (e.g. /home partition)
+
+ * configure dovecot fs quota plugin. for details see below.
+
+ * use doveadm command to verify the result:
+ $doveadm quota get -u user
+ The result is shown in kb and as a percentage value
+
+ [Regression Potential]
+
+ * only users using the fs quota plugin are affected
+
+
+
Packages:
dovecot 2.2.33.2-1-ubuntu4.1
ubuntu 18.04.1 LTS
-
The quota is erroneously calculated with the fs quota plugin.
It was working fine on ubuntu 16.04 with the same config.
Quota configuration:
plugin {
- quota = fs:User quota
+ quota = fs:User quota
}

Storage should actually be around 2775445 KB.
The quota is correct from my ext3 filesystem quota of 4096001 KB.
