[LU-19028] Fixing the squash value in the nodemap configuration.

• Type: Bug
• Resolution: Unresolved
• Priority: Minor
• Severity: 3
• Assignee: Sebastien Buisson
• Reporter: Srinidhi Gubbi

Description

Steps to reproduce the problem:
1. Configure a nodemap (noRootSquash) on MGS with:
trusted=1
admin=1
squash_uid=0
squash_gid=0
Client NIDs correctly added to the nodemap ranges.
2. Mount the Lustre filesystem on a client listed in the nodemap range.
3. As root user (uid=0) on the client, attempt to:
touch a new file on the Lustre mount.
mkdir a new directory under the mount.
ls or chown inside existing user-owned directories.
4. Result:
Permission Denied errors are observed.
Root user cannot create files or directories on Lustre, despite nodemap settings intended to disable root squash.
5. Filesystem remounts have been attempted — no change.
