  Hi!
  I have a bug with my iredadmin v.1.6.
  After connecting a new disk for mail accounts, the total quota is displayed incorrectly, while everything works correctly. I attach a screenshot where you can see that more space is used than everything. The total disk size is 1 TB.
  

There is also a bug with the mariadb database - I cannot connect to it using "mysql -uroot -p", I get the error "ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)", so as there is no folder created along this path, although everything worked before and I could connect.
The mysql folder is missing or has been deleted, although I did not do it.
