[LU-16887] scrub does not handle OI->wrong inode situation

Tue, 20 Jun 2023 17:27:21 +0000

The simple case when file is removed with ldiskfs mount leads to situation when OI exist and points to inode, but inode is reused. For such fid osd_fid_lookup() will always return EINPROGRESS. Scrub doesnot handle this problem.
The next check compares two oi records(from inconsistent list and a fresh oi from fid) and decides that oi is fine. But unfortunately it was added to inconsistent list base on wrong inode.

  } else if (osd_id_eq(lid, lid2)) {
               if (converted)
                       sf->sf_items_updated++;
               GOTO(out, rc = 0);
}
