I created a server and gave him a device (hdd). After a while I tried to change the size of this device and it gave mit the following error:
Fatal error: Call to undefined method isys_cmdb_dao_storage_device_hd::set_status() in /path/src/classes/cmdb/dao/isys_cmdb_dao_storage_device.class.php on line 633
This bug appeared in former versions of i-doit, but it was fixed for v0.9.3.
Are you operating the latest version of i-doit?
