Can I replace a corrupted Home LVM?

Sorry to have to add one more question to the ever growing mass of queries this website is accumulating, but I feel that it would be best for me to seek out expert advice before proceeding with my endeavour. Earlier today various unpleasant problems and events caused a crash on one of my Fedora systems, this one a relatively recent install of Fedora 14. The Root LVM managed to survive intact, but the Home LVM has become plagued with literally thousands of file-system errors. This in the end is not a catastrophe as the system itself is simply a play system to allow me to experiment with AMD's Catalyst binary drivers.

Still, I wish to recover the system as much as I can and return it back to working order. I have already tried to recover the Home LVM using the "fsck -a" command, but it keeps having to be re-prompted by me to continue and at this rate it will not be done until after the sun goes supernova and all life on earth has perished. A little bit of hyperbole there I grant you, but it seems to me to be only a slight exaggeration. As there is not anything of particular significance on the drive, I am wondering if it might just be best to overwrite the old Home LVM with a fresh file-system. Can this be done and if it can how can it be done?

I eagerly await the advice of our resident Fedora masters.

It's not as bad as you write, long before the sun goes supernova, it's capacity will decrease
and everything including your fsck will stop in a icy world
But if the LVM has no value, then you could easily use "mkfs <id of the home lvm> to create a new filesystem on it. Be sure to create the new home directory with the proper uid, gid and permissions

Good luck!

Well, it looks like I may have been a bit quick to declare the LVM dead. Turns out it was a problem with a bad Suoerblock, fixed that from the Live CD, and then ran fsck again. This time all the errors became fixed, and I am now posting from the system in question with no apparent data loss what so over.

Three cheers for Ext! WOOO!
