My four HDDs were connected to a faulty serial SATA power. The thing was working fine till I made a restart today and power for two HDDs failed, upon checking the web interface first it showed me only 2 HDD and later none.
I fixed the power issue but once the system came up there are no RAIDS to display in RAID Management, and the file system tab show n/a.
From another thread I tried the following command which too didn't do any help.
This is the output for cat /etc/fstab :

This is the output of cat /etc/mtab :
This is the output for blkid :

The data is really important.
