degradacja RAID1
: 28 czerwca 2016, 11:33
Witam
Server to NAS d-link-320, postawiony na nim Debian
po restarcie maszyny okazało się że rozsynchronizował sie RAID1. Z poziomu panelu konfiguracyjnego nic nie moge zrobić, prócz formatowania itd...
natomiast liknuksik pokazuje:
natomiast fdisk
jeszcze MDSTAT
Proszę o wskazówki jak się z tym uporać i nie stracić danych 
dzięki
