Hello, I have a little more information about the bug with the new mount command in util-linux-2.12a-16.EL4.25. the bug is described in : https://www.scientificlinux.org/bug.feature/bugs/12/pcng_issue_view https://www.scientificlinux.org/bug.feature/bugs/13/pcng_issue_view But there is also an other strange problem with NFS mount : [root@cobb ~]# mount /distrib_labo mount: distribhost:/distrib failed, reason given by server: Permission denied [root@cobb ~]# host distribhost distribhost.lmd.jussieu.fr is an alias for moreau.lmd.jussieu.fr. moreau.lmd.jussieu.fr has address 134.157.47.150 but if I use the real name of this NFS server it works ! [root@cobb ~]# mount moreau:/distrib /distrib_labo [root@cobb ~]# we have other aliases (CNAME) for this host that works ! for example divhost [root@cobb ~]# host divhost divhost.lmd.jussieu.fr is an alias for moreau.lmd.jussieu.fr. moreau.lmd.jussieu.fr has address 134.157.47.150 [root@cobb ~]# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda8 18145092 4543564 12679804 27% / /dev/sda6 101086 12736 83131 14% /boot none 1036736 0 1036736 0% /dev/shm /dev/sda9 35364848 17043960 16524424 51% /home b8tohost:/d3 1952340608 1949047808 3292800 100% /d3 b8tohost:/d4 976443392 128832512 847610880 14% /d4 b8tohost:/d5 624191872 405432960 218758912 65% /d5 b8tohost:/d6 975817600 813442688 162374912 84% /d6 b8tohost:/d7 976395904 684127968 292267936 71% /d7 divhost:/cycleco2 389156992 104724256 280525632 28% /cycleco2 <=== @@@ works with alias divhost:/meteoparis 389156992 104724256 280525632 28% /meteoparis <=== @@@ " " " bizet:/u 310044640 124570784 173072064 42% /home/users moreau:/distrib 389156992 104724256 280525632 28% /distrib_labo <=== @@@ doesn't divhost:/db1 389156992 104724256 280525632 28% /db1 <=== @@@ works with alias It would be nice if you put the previous version till it works.
