Description of problem: Files with UIDs higher than 2^16-1 are owned by "nfsnobody". Version-Release number of selected component (if applicable): n/a How reproducible: Create a user with UID higher than 2^16. Check ownership of the files on a RHEL3 box Steps to Reproduce: 1. 2. 3. Actual results: User: jl186060 jl186060::70253:70253:John G.

Large UIDs certainly work on the local filesystem (just verified), so if it doesn't work with NFS, it is either NFS limitation, or kernel bug.
I get the proper username/group under Solaris 8 on the same NFS mount. So it's definately a limitation in Linux. Is there a workaround for this? We really need to have those UIDs > 2^16-1 working. Gr, Xander
I am having problems with large uids on local file system (ext3) as well. Kernel: 2.4.21-15.0.3 (RHEL) CPU: x86_64 [root@rijkes-n-d00022 mightor]# id mightor uid=777777(mightor) gid=777777(u_777777) groups=777777(u_777777) [root@rijkes-n-d00022 home]# chown mightor:u_777777 mightor [root@rijkes-n-d00022 home]# ls -ld mightor drwx------ 4 nfsnobody nfsnobody 4096 Aug 17 10:15 mightor [root@rijkes-n-d00022 home]# ls -lnd mightor drwx------ 4 65534 65534 4096 Aug 17 10:15 mightor What did you do to make it work on the local filesystem? Gr, Xander
FYI. It appears the new kernel (2.4.21-20.EMPsmp)fixes this problem for the IBM AMD Opteron.
Assigned to RHEL3 kernel team lead. Note that RHEL issues are best handled through support, who are better set up to handle ongoing customer issues. Bugzilla is more of an engineering tool... https://www.redhat.com/apps/support/
Should be fixed in nfs-utils-1.0.6-33EL
