Witam
Zainstalowałem iscsi i niby wszystko działa. Na initiatorze pojawiają się dwa dyski jednak gdy z poziomu initiatora próbuję zapisać cokolwiek to jest to do momentu restartu maszyny. Wydaje mi się że dane powinny się zachować o być widoczne również z poziomu targetu a tak nie jest. Identycznie jest z poziomu targetu gdy próbuję stworzyć plik lub folder - nie jest on widziany przez initiatora.
Dyski logiczne które udostępniam zostały stworzone podczas instalacji systemu i są to macierze w Raid5 o pojemności 200 GB.
