Hi all, i've problem with mounting logical volumes over NFS.
On NFS server, i have following logical volume [root@nfs_server ~]# lvdisplay --- Logical volume --- LV Name /dev/escience/vv_25 VGnfs_servernfs_servernfs_servernfs_servernfs_server escience LV UUID iMhNq7-iC7L-VTDO-Xcwv-a6yv-sEAD-EZWASV LV Write Access read/write LV Status available # open 0 LV Size 5.00 GB Current LE 1280 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:2
This logical volume is mounted on NFS server, the group information is taken from LDAP server. [root@nfs_server ~]# mount | grep vv_25 /dev/mapper/escience-vv_25 on /export/escience/vv_25 type ext3 (rw) [root@nfs_server ~]# ls -ld /export/escience/vv_25 drwxrwx--- 3 root vv153 4096 Jun 24 16:04 /export/escience/vv_25
But when i mount /export/escience on the nfs client, i'm missing all the permissions and ownership informations: [root@client ~]# mount.nfs nfs_server:/export/escience/ /mnt/escience [root@client ~]# ls -ld /mnt/escience/vv_25 drwxr-xr-x 2 root root 4096 2009-06-24 16:04 vv_25
The setting of NFS exports is following: [root@nfs_server ~]# cat /etc/exports /export/escience client(rw,sync,no_root_squash) [root@nfs_server ~]# exportfs -v /export/escience client(rw,wdelay,no_root_squash,no_subtree_check,anonuid=65534,anongid=65534)
Server is running latest CentOS 5.3 [root@nfs_server ~]# cat /etc/redhat-release CentOS release 5.3 (Final) [root@nfs_server ~]# uname -a Linux nfs_server 2.6.18-128.1.14.el5 #1 SMP Wed Jun 17 06:38:05 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
No denials from selinux, client's IP is completely opened on firewall.
Is there some possibility to debug the NFS mount process? I don't see nothing more then verbose mode in man, which doesn't provide much informations :( Or is it some configuration issue?
