It seems to be. te case. A few weeks ago, I was on travel, and reduced a
partition, and it did not come back after reduction. I did it the same
way as I always do...resize, reduce, remount. When I tried to remount,
it gave me the bad filesystem error...
so I thought that might be the problem.

Thanks for clarifying.
