Just inherited a broken server (the previous admin retired - leaving no documentation). Upon analysis it seems the OS Debian bookworm was installed on a hardware RAID1 (using MegaRAID 9560-8i 4GB). Root partition had no backup/clone elsewhere. Data is stored on different disks RAID6 and is healthy.
- since always used software RAID and ZFS, I have no idea.
- Is it possible to FSCK or run some tools to revive or clone the root/file system as we need the usernames - (i.e) /etc/{shadow,passwd} etc of all the users. Nothing else is needed.
- Following is the output from storcli

I am aware this is not r/techsupport but I know people have significant skills on RAID etc.
I am grateful for any suggestions.
