There's a way to fsck with alternate superblocks. There's a way to use
newfs to tell you what those would be. For better answers provide
system details.

1. Please don't top-post, it really farks up any hope of quoting with
context.

2. How are your backups.

no backups at all.

Go to the single user prompt. Comment out /home from /etc/fstab
then reboot. Once up run newfs or mkfs on the new partition.

Lessons learn - Don't resize mounted partitions unless the tool you
are using explicitly supports that. Do read all the man pages on
both LVM and filesystem layer. Do make backups before doing
changes.

it wont let me edit fstab. says read only file

What part of "don't top-post because it ****s up being able to
communicate effectively" are you having a hard time with.

Sounds like you've got the potential to learn several useful things from
this experience. Or not. Your choice.

More like read-only filesystem. Check the man pages for fsck
and mount (look for -o remount).

Some folks don't get that UseNet has been around for decades
and has the standards it has for good reasons.
