Hi everyone,

I have a problem regarding to file system error actually i had reduce size directly of a volume group /dev/vg0/data without shrinking it first and then reducing it ..everything was alright at that time but when i reboot my system i had seen a black screen showing file system inconsistency or superblock my be corrupted due to which i am not dropped on shell and ask about root password to continue or press ctrl+d to reboot it. you can see the snapshot of that in attatchment for reference. i dont want ot reinstall linux i just want to sort out this problem i done my best but no luck. Hope you help me on this matter.

If I understand correctly what you did, you will need to resize the vg back to (at least) the same size (Edit: - do it from a live/install CD that has LVM support).
Best would be to restore the filesystem after thaat, before attempting a resize, just to be sure the filesystem hasn't been damaged.

Then do the resizing in the correct order - tldp.org has a LVM how-to that describes this.
