Description

Most of the files are not accessible after 2.12 -> 2.15 upgrade:

[root@hpcln01 ~]#  ls /mnt/lustre
ls: cannot access '/mnt/lustre/README': No such file or directory
ls: cannot access '/mnt/lustre/other': No such file or directory
ls: cannot access '/mnt/lustre/vol0': No such file or directory

The system had been functioning correctly before the upgrade.

The server's kernel log contains messages like the following:

Mar 20 11:33:04 hpcln02 kernel: LustreError: 1764712:0:(mdt_open.c:1519:mdt_reint_open()) hpcln-MDT0000: name 'README' present, but FID [0x200016cab:0x1e5:0x0] is invalid
