You may however not be seeing the same bug on Fedora. Ian *** This bug has been marked as a duplicate of bug 866271 *** I've had a really close look at internal data found at Fedora 17,18 and RedHat EL 6.3. Same problem. This has an other side effect: create an export: /data/share/home *.somedomain.example(rw,sync,no_root_squash,no_all_squash) mount it on two different servers: clt1# mount srv:/data/share/home /home clt2# mount srv:/data/share/home /home on clt1: drwxr-xr-x. 109 root root 12288 7. Dez 13:14 etc drwxr-xr-x. 2 root root 4096 3. Dez 15:22 home dr-xr-xr-x. 11 root root 4096 12. Okt 17:19 lib on clt2: drwxr-xr-x. 115 root root 12288 7. Dez 13:25 etc drwxrwxrwx 7 nobody nobody 4096 7. Dez 11:15 home dr-xr-xr-x. 11 root root 4096 6. Nov 08:22 lib On clt2 *all* is mapped to nobody:nobody, as if "all_squash" had been given in exports. Maybe this is an additional error with this particular kernel. I'm trying to down/upgrade the kernel to the most recent one now, because nfs seems seriously broken with this one on RedHat EL 6.3 "uname -a" gives back on all three systems: Linux srv 2.6.39-300.17.2.el6uek.x86_64 #1 SMP Wed Nov 7 17:48:36 PST 2012 x86_64 x86_64 x86_64 GNU/Linux |
