[lustre-discuss] Can't find FID Sequence 0x0: rc = -115

[rodger]

Dear All,

I posted regarding my issues with OST indexes in upgrading from 1.8.9 to 
2.10. Thanks to help from responses on the list I have correct indexes 
assigned to various OSTs.

On the OSS I now have errors similar to:

Sep 27 20:31:39 oss3l210 kernel: LustreError: 
3581:0:(ofd_dev.c:1592:ofd_create_hdl()) terra-OST0007: Can't find FID 
Sequence 0x0: rc = -115

And on the MDS:

Sep 27 20:01:18 mds0l210 kernel: LustreError: 
2854:0:(osp_precreate.c:903:osp_precreate_cleanup_orphans())

An 'ls' of most directories on a client machine does not return. An 'ls' 
of the top level directory returns. The few files in this directory are 
readable but any attempt to lower levels fails. lfs find and lfs 
getstripe on files returns quickly and appears to show meaningful data.

Please advise on troubleshooting steps.

Many thanks,
Rodger
