You may simply be able to "unlink" the file/directory without bringing down the OST.  I've done this in the past with individual lost files.

I had the same problem. And I resolve the problem by the next way, BUT I THINK NOT IS A GOOD IDEA THIS SOLUTIONS, BUT FOR NOW THIS WAY HAS SOLVED MY PROBLEM:

1) umount MDT

2) mount your MDT with “-t ldiskfs”

3) Enter intro the directory that you had mounted your MDT

4) Go to the ./ROOT/….. directory and erase the directory or files you don’t want anymore.

5) mount again the MDT with “-t lustre”

Hi,

After an ost failure (which is deleted today), i have a folder wich does not exist anymore because it was on this OST, but it still appears in my filesystem(still exist in the MDT i think), and if i want to remove it, it tells me that the object doesn't exist, i can't make anything with it and I don't know how to clean it !

Can you help me ?

Thanks.
