{path} is to be interpreted by robinhood, not by bash.
So you should change your action to:
default_action = cmd("/root/list_NA30d.sh {path}");
and your script:
#!/bin/bash
echo "$1" >> /tmp/`date "+%Y%m%d"`_NAo30D.lst
Notice that I also dropped "+%Y%m%d%H%M.%S" that changes every second and so it
may create many output file...
I suggest instead you just use date "+%Y%m%d", so they will all be written to
the same file for a given run (if there is no day change while it's running...)

Hi Thomas,

After modified default_action from cmd("/bin/rbh-find /work1/ -mtime +30 >
/tmp/NAo30D.lst") to cmd("echo {path} >> /tmp/NAo30D.lst") and ran robinhood
--run="check_idle" --once again, those processes rbh-find terminated.
Do you have any idea about output an files which we applied policy on it?
I have tried to produce list of files but always fail:
-bash-4.2# cat /etc/robinhood.d/includes/check_idle_30d.inc
define_policy check_idle {
status_manager = basic;
scope { type == file and status == ""}
default_action = cmd("/root/list_NA30d.sh");
default_lru_sort_attr = none;
}
check_idle_trigger {
trigger_on = periodic;
check_interval = 30d;
}
-bash-4.2# cat /root/list_NA30d.sh
#!/bin/bash
echo {path} >> /tmp/`date "+%Y%m%d%H%M.%S"`_NAo30D.lst
Here is what we got:
-bash-4.2# tail /tmp/201610071530.36_NAo30D.lst
{path}
{path}
{path}
{path}
{path}
{path}
{path}
{path}
{path}
{path}
Is there any method which we can produce list file?(redirection is not working
in robinhood)
Regards

Hi Thomas,
Thanks for your explanation.
We ran the command several times to test policy:
robinhood --run="check_idle" --once
Original setting is that running policy per hour, we modified it to 30 days
then.
However, we found that there are several processes still running on system.
-bash-4.2# ps -ef | grep rbh-find
root 38536 10473 9 09:40 ? 00:00:09 /bin/rbh-find /work1 -mtime
+30 > /tmp/NAo30D.lst
root 38537 10473 9 09:40 ? 00:00:09 /bin/rbh-find /work1 -mtime
+30 > /tmp/NAo30D.lst
root 38538 10473 10 09:40 ? 00:00:09 /bin/rbh-find /work1 -mtime
+30 > /tmp/NAo30D.lst
root 38539 10473 9 09:40 ? 00:00:09 /bin/rbh-find /work1 -mtime
+30 > /tmp/NAo30D.lst
Tried to stop then start robinhood daemon, but daemon always startup those
processes.
Is there any method that we can stop those processes?
I think there is something to do with the systemd configuration.
@Dominique, can you give him an hint?
BTW, thinking about your policy rules, this should be more efficient and make
it possible for robinhood to optimize its DB query:
check_idle_rules {
ignore { last_mod < 30d }
rule default {
condition { last_access > 30d }
}
}
This way robinhood will only select entry with last_mod > 30d from the DB
and then stat the entry to check its atime, and then do the policy action.
Thomas.

Hi,
I define policy as following:
-bash-4.2# cat /etc/robinhood.d/includes/check_idle_30d.inc
define_policy check_idle {
status_manager = basic;
scope { type == file and status == ""}
# only for policy matching, not to display in reports
(cosmetic. you can remove this comment. It should be about a line you deleted).
default_action = cmd("/bin/rbh-find /work1/ -mtime +30 > /tmp/NAo30D.lst");
You have to know that this action is run for every entry that matches your
policy rule!
So in this case, you run the same find command for many entries!
If I correctly understand what you want to do, your policy rule condition
should be:
{last_access > 30d and last_mod> 30d}
and the action should be something like:
echo {fullpath} >> /tmp/your_list
(not sure how robinhood commands manages redirections like > or >> in commands,
but you can still write a script process_entry.sh that does this).
Hope this helps,
Thomas
default_lru_sort_attr = none;
}
check_idle_trigger {
trigger_on = scheduled;
check_interval = 1h;
}
rule in /etc/robinhood.d/<filesystem>.conf
check_idle_rules {
rule default {
condition { last_access > 30d }
}
}
What the policy is testing to produce an list which files have not been access
over 30 days.
We found that it took long time that just run job directory with command line
"/bin/rbh-find /work1/ -mtime +30 > /tmp/NAo30D.lst".
Could you please give a clue about the issue?
