I have to remove an OST because of a drive problem, however if I unmount

You have to deactivate the OSCs that reference that OST. From
https://mail.clusterfs.com/wikis/lustre/MountConf:
As of beta7, an OST can be permanently removed from a filesystem. Note
that any files that have stripes on the removed OST will henceforth
return EIO.
