forgot to mention that I could not find any info in [1] too about a
necessity to share $ONE_LOCATION/share/hooks dir across CNs in case if
hooks has to be executed on remote node. So I wonder if
$ONE_LOCATION/share/hooks needs to be available across CNs if there is
hook to be executed on CNs or there is some built-in mechanism in ONE
which transfers such hooks to CNs but for some reasons it didn't work in
my case?

Hi!
I am trying to run some custom hook on remote/cluster node.
I defined the hook as below:
oned.conf:
VM_HOOK = [
name = "vzfirewall",
on = "RUNNING",
command = "vzfirewall.sh",
arguments = "",
remote = "yes" ]
and create the vzfirewall.sh file:
$ ll $ONE_LOCATION/share/hooks/vzfirewall.sh
-rwxr-xr-x 1 oneadmin cloud 42 Aug 1 22:00
/srv/cloud/one/one-2.2.1/share/hooks/vzfirewall.sh
with the following content:
[FN]$ cat $ONE_LOCATION/share/hooks/vzfirewall.sh
#!/bin/bash
sudo /usr/sbin/vzfirewall -a
So that hook has to invoke /usr/sbin/vzfirewall script located on all CNs.
[CNs]$ ll /usr/sbin/vzfirewall
-rwxr-xr-x 1 root root 7661 Jun 4 13:36 /usr/sbin/vzfirewall
After defining that hook in oned.conf the oned had been restarted and in
oned.log the relevant line appeared:
[...]
VM_HOOK=ARGUMENTS="",COMMAND=vzfirewall.sh,NAME=vzfirewall,ON=RUNNING,REMOTE=yes
[...]
But when VM reaches the RUNNING state on CN, the following errors appear
in the oned.log:
[...]

So I wonder if $ONE_LOCATION/share/hooks/ dir must be mounted on CNs in
case if hook needs to be executed there (i.e. on remote node)?
I didn't find corresponding info neither in [1] nor in [2].
