    Description

      ostid_set_id() can overwrite error code from ofd_precreate_objects(). this may lead to a set of issues on MDS side (misleading error message, RPC storm, etc).

       LustreError: 26378:0:(ofd_dev.c:1784:ofd_create_hdl()) nbp13-OST0008: unable to precreate: rc = -115

      The -115 = -EINPROGRESS error is because the LMA FID is bad and LFSCK has started OI Scrub. The error is not returned to the MDS, but it created no objects and hits the error in osp_precreate_send() and spins on precreate because there are no errors reported on the OST.

            The {{-115 = -EINPROGRESS}} error is because the LMA FID is bad and LFSCK has started OI Scrub. The error is not returned to the MDS, but it created no objects and hits the error in {{osp_precreate_send()}} and spins on precreate because there are no errors reported on the OST.
