description: you can have per VE mount/umount scripts /etc/vz/conf/${VEID}.{mount|umount} or mount/umount scripts which all VEs will run /etc/vz/conf/vps.{mount|umount} In case of no-zero exit code of mount script the VE won't be started You would probably want to move /vz/private/200/home/xxx to /vz/home/xxx (or somewhere else and bind mount it both from /vz/root/200/home/xxx /vz/root/300/home/xxx mount --bind /vz/home/xxx /vz/root/200/home/xxx mount --bind /vz/home/xxx /vz/root/300/home/xxx In case you don't want the umount scripts then bind mount with -n option mount -n --bind /vz/home/xxx /vz/root/200/home/xxx mount -n --bind /vz/home/xxx /vz/root/300/home/xxx

Re: how to create a mount script

description: Hello, I am attempting to do a bind mount on my test VE 1040. For testing purposes, I just want to mount /home/jdw on the host node into /home in VE 1040. I know this isn't a proper setup, but I'm just trying to get the format of the mount script correct. It seems to me that all I would have to put into /etc/sysconfig/vz-script/1040.mount is: mount -n --bind /home/jdw /vz/private/1040/home however, when I attempt to start VE 1040 with this mount script in place I get the following error: Starting VE ... Error exec /etc/vz/conf/1040.mount: Exec format error Error executing mount script /etc/vz/conf/1040.mount The mount -n --bind /home/jdw /vz/private/1040/home works on the host node at the command line so the format appears to be correct. I have also tried mounting to the VZ root instead of private area as I am not clear where I should be mounting to. The HN is openvz 2.6.18-53.1.4.el5.028stab053.4 and VE 1040 was built with the centos-4-i386-default template. Any ideas what I'm doing wrong? Thanks Jon

description: Hi Jon, 2 things: a) I believe that you shouldn't do the bind mounts to /vz/private/.../ but to /vz/root/.../ (could someone please confirm this?) b) does your mount script only contain the one line with the mount command? If so, try to make it look that way: #!/bin/sh mount -n --bind /home/jdw /vz/root/1040/home and be sure to set the executable flag for the script: chmod +x /etc/sysconfig/vz-script/1040.mount I'm not an openvz expert but that's the way it works for me greetings, Hubert

description: Aha. I was missing the shebang because sh is in my path. Apparently it needs to be specified for the mount script to work. Thanks! Jon

description: Hi. I'm trying what you suggest here, but I don't make it to work. My mount script: #!/bin/bash mount --bind '/vz/mounts/gridlog/psql' /vz/root/3000'/var/lib/pgsql' All directories exist: $ ls -lhd /vz/mounts/gridlog/psql /vz/root/var/lib/pgsql drwxr-x--- 2 root root 4.0K May 7 19:40 /vz/mounts/gridlog/psql/ drwxr-x--- 2 root root 4.0K May 7 20:45 /vz/root/3000/var/lib/pgsql/ But I get the following error if I try to start VE 3000: Quote: Starting VE ... mount: mount point /vz/root/3000/var/lib/pgsql does not exist It doesn't work if I replace /vz/root with /vz/private, or I change the permissions or I add '-n' to the mount invocation. I'm using vzctl-3.0.22-1 . Any ideas? Thanks a lot.

description: /vz/root/3000/ get mounted from /vz/private/3000/ then VE startsup, so you need to create /vz/private/3000/var/lib/pgsql/ instead so make shure /vz/private/3000/var/lib/pgsql dir exists prior to starting 3000 VE
