Description

Hi, we noticed the following minor issue when trying to add our IB network 10.210.32.0/20 to nodemap:

$ lctl nodemap_add_range --name sherlock --range 10.210.[32-47].[0-255]@o2ib3
error: nodemap_add_range: nodemap ranges must be contiguous
$ cat /proc/fs/lustre/nodemap/sherlock/ranges
[

]

The workaround is either to add 16 separate entries (10.210.32.[0-255], 10.210.33.[0-255] etc.), or a single larger range (whenever possible).

Thanks,
Stephan
