[International / GSM] Error mounting /data and /sdcard in CWM

I have a close to catastrophic situation with my rooted GNex. It had one of AOSP over a month, did CWD backup every three to four days since day 1, and last night all of sudden, my attempt to backup failed with unknown error. It rebooted in CWD recovery mode, loaded commands during backup and at the end it stopped with no specific errors. Then nightmare started:

- Tried to restore using saved backed up image, none worked with the same unknown error
- Tried every menu in CWD recovery, factory reset, wipe cache/dalvik cache/data before recovery, fix permission, format/unmount/remount all
- Locked and unlocked bootloader as it got stuck at boot, this is how sdcard content was erased
- Now it shows Error mounting /data and /sdcard
- Ran CWD from windows using fastboot boot CWD, tried adb push AOSP.zip /sdcard and it finished transfer but when trying update zip from sdcard, it couldnt remount /sdcard
- Tried "Partition SD Card" and created new one but still can't remount /sdcard

Can anyone please help how to fix this? I am not quite familiar with linux so if you write down the whole commands to run, I appreciate it
 
After boot, I got in CWD and tried to mount system, cache, data, USB storage, and got:

Error mounting /cache!
Error mounting /data!
E:Unable to open ums lunfile (no such file or directory)

From ADB:

adb shell mount /data
mount: mounting /dev/block/platform/omap/omap_hsmmc.0/by-name/userdata on /data
failed: Invalid argument

adb shell mount /cache
mount: mounting /dev/block/platform/omap/omap_hsmmc.0/by-name/cache on /cache failed: Invalid argument
