[one-users] Errors in tm_clone.sh for NFS hosts

Tue Apr 19 06:58:27 PDT 2011

This is looking more and more like a bug or variable scope issue.

I added the following to /usr/lib/one/tm_commands/nfs/tm_clone.sh:

log "SRC Value: $SRC"
log "DST value: $DST"

(after the line "get_vmdir")

The log entries now say:
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: SRC Value: io-kvm-ctrl-01.streamsage.com:/home/oneadmin/one-templates/ttylinux.img
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: DST value: sn-kvm-11:/srv/cloud/one/var/59/images/disk.0
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: io-kvm-ctrl-01.streamsage.com:/home/oneadmin/one-templates/ttylinux.img sn-kvm-11:/srv/cloud/one/var/59/images/disk.0
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: DST: /var/lib/one/59/images/disk.0

Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: Executed "chmod a+w /var/lib/one/59/images".
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: Cloning /home/oneadmin/one-templates/ttylinux.img

Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: Executed "chmod a+rw /var/lib/one/59/images/disk.0".

So DST has the correct value: /srv/cloud/one/var/59/image/disk.0. But two log lines later, DST is set to: /var/lib/one/59/images/disk.0
Tue Apr 19 09:39:30 2011 [TM][I]: tm_clone.sh: DST: /var/lib/one/59/images/disk.0

So somewhere in the sub-routine "fix_paths" we're picking up /var/lib instead of /srv/cloud/???

For now I've commented out "fix_paths" in tm_clone.sh and fix_dst_path in /usr/lib/one/tm_commands/nfs/tm_context.sh and it's now creating virts on my NFS enabled hosts.

Subject: Errors in tm_clone.sh for NFS hosts

I think this one is pretty straight forward, I just need someone to tell me where I set it.    When I try to create a virt on a tm_nfs target, the tm_clone is cloning into the wrong directory.

It says its trying to do it right:
 tm_clone.sh: io-kvm-ctrl-01.streamsage.com:/srv/cloud/var/images/83603da305e13410317b0c947f435a019644f46f sn-kvm-11:/srv/cloud/one/var/56/images/disk.0

/srv/cloud/one/var/56/images is the correct target path, but the clone script  appears to be putting it in:  /var/lib/one/56/images/disk.0
tm_clone.sh: DST: /var/lib/one/56/images/disk.0

Where do I set the variable for the tm_nfs config to not use '${ONE_LOCATION}' for the destination but rather use the /srv/cloud/one/var/ (/srv is the NFS mount common to both the oneadmin control box and the target host).

The log file of a failure:
