thank you for her advice. Btw, what is the min required HDD/SDD space for main drive to get Synolgy with SS worked. Looks that I have the same problem as it was descibed bellow. I have 32Gb main disk and 1Tb extra one for SS videos. My SS is conf. so that it keeps and stores the records at my second drive that is 1Tb (so,shared folder for SS is located there). After 2 days of usage fresh installation of DVA1622, I got a message than my 32Gb is full, so -> no further real work : SS is not working etc (and have no idea which type of data made it full). I have virtual machine that is installed under VMWare ... does someone met the same issue on Vmware or just 32Gb is not enough as primary drive for my DVA1622?
