Description

Hello,

I attempted to add a new range to a nodemap that we use in production here, and got the following error:

[root@rds-mds10 ~]# lctl nodemap_add_range --name csd3 --range 10.43.240.[198-199]@tcp2                                                                                                                                                                        
error: invalid ioctl: 000ce042 errno: 12 with rc=-1
error: nodemap_add_range: cannot add range '10.43.240.[198-199]@tcp2' to nodemap 'csd3': rc = -1

With the following in syslog:

Jul 16 15:27:08 rds-mds10 kernel: LustreError: 111140:0:(nodemap_handler.c:812:nodemap_add_range_helper()) cannot insert nodemap range into 'csd3': rc = -17

The environment of this server is:

[root@rds-mds10 ~]# lfs --version
lfs 2.12.5
[root@rds-mds10 ~]# uname -r
3.10.0-1127.8.2.el7_lustre.x86_64

Do those errors give any clue as to what the cause of the problem is here?

Thanks,
Matt
