Well I will answer my own question,
Problem was that I put a 20gb disk to install packages, there I Installed PLEX, Surveillance Station, and lots more, but the 20gb went short, and fill the disk, so I removed the disk, put a new vd disk with bigger size, rebooted and wala, dsm, nginx worked, saying i lost the apps, so i have to reinstall all the apps, at least did not loose any info or data.
