Hi all,
- Lustre 2.15.4 test system with MDS + 2 OSS + 2 administrative clients.
I activated nodemapping and put all these hosts into an "Admin" nodemap, which has the properties
`admin=1` and `trusted=1` - all works fine.
Now there are a couple of other hosts which should not become administrative clients, but just
standard clients => they should be / remain in the "default" nodemap.
The "default" nodemap has `admin=0` and `trusted=0`, as verified by
`lctl get_param nodemap.default....`
- and these hosts cannot mount.
Error message is "l_getidentity: no such user 99"
I verified that these hosts actually are seen as "default" nodes by setting `admin=1` for one of them
- mounts.
Umount, lustre_rmmod, set `admin=0` again - does not mount anymore.
Atm I do not see what I overlooked, but I am certain this has worked before, where "before" would mean
other hardware and perhaps Lustre 2.15.1
*Switching* is still ok:
- Put client X into "Admin" nodemap, mount Lustre, remove client X from "Admin" nodemap, wait, try to
`ls` as root - fails.
Set the property `trusted=1` on the "default" nodemap, wait, try to `ls` as a
user - works.
However, this defeats the purpose of having a usable default...
Regards,
Thomas
