Hello

I recently had the same objectives to mount cifs on a CT

1) mount it on the Host node (hypervisor)
2) attache it to the CT

1) is what you already did
2) I did that :
# vzctl set CTname --bindmount_add /mnt/hostdisk:/mnt/ctdisk --save

so the host node FS mounted at /mnt/hostdisk will be presented on /mnt/ctdisk in the CT

that works fine, exept that you cannot migrate your CT to an other host node without pepraring the host mount on the destination . beware also if you use cifs mount options like uid=1000,gid=1000, those ids are should match ids on the CT .

regards .

Hello list,

Hoping someone can help, (forum registration is closed) I'm trying to bind a samba share from the host to the OpenVZ container, but when I do the directory on the container is empty. I've tried to follow https://wiki.openvz.org/Bind_mounts however I think it's out of date as it refers to simfs which I don't have. I made the directory permissions open and selinux is disabled.

- Here's the layout:
NAS ---(CIFS)---> Virtuozzo-Server ----(BIND Mount)---> OpenVZ-Container
Virtuozzo, OpenVZ release 7.0.16

Here's what I've done:

1. Mount CIFS share on the host:
[root@openvz conf]# mount -t cifs //server/directory /mnt/disk -o username=user,vers=3.0,file_mode=0775,dir_mode=0775

2. Run the bind mount (I've tried a few variations of this):
[root@openvz conf]# mount -v --bind /mnt/disk/ /vz/root/101/mnt/disk/
mount: /mnt/disk bound on /vz/root/101/mnt/disk.

- Here's what it looks like on the host:
[root@openvz conf]# ls -l /mnt/disk/ | wc -l
234
[root@openvz conf]# ls -l /vz/root/101/mnt/disk/ |wc -l
234

- ...On the container (101):
[root@computer1 ~]# ls -l /mnt/disk/
total 0


Anyone have any ideas what's going on? It's causing real dramas here.

Kind regards,
Mike.
