After upgrading to nfs-utils-lib-1.1.5-6.el6_5 nfs mounts do not work anymore. export on server is done with: (rw,sync,root_squash) mount on client is done with autofs -fstype=nfs,nosuid,nodev,soft,bg,nfsvers=3 I get this in syslog: Aug 5 12:50:14 client nfsidmap[1351]: nss_getpwnam: name 'root@example.com' does not map into domain 'sub.example.com' Downgrading to nfs-utils-lib-1.1.5-6.el6.x86_64 fixed the problem. regards, Giannis
Steve, Unfortunately, I don't think this fix resolves the problem. I've installed the updated nfs-utils-lib-1.1.5-6.el6_5 # rpm -q -a | grep nfs-utils-lib nfs-utils-lib-1.1.5-6.el6_5.x86_64 I'm also running the latest kernel 2.6.32-431.23.3.el6. On client NFSv4 share is mounted like this: hard,intr,bg,tcp,acl On server it is exported to this client like this: rw,sync,no_root_squash On client, after mounting filesystem: # touch newfile newfile shows as owned by "root". # chown root:root newfile # ls -al newfile -rw------- 1 nobody nobody 0 Aug 5 09:34 newfile Syslog: Aug 5 09:25:12 elf elf nfsidmap[5076]: nss_getpwnam: name 'nobody' does not map into domain 'cs.yorku.ca'
