Hello,
I have a new install of Robinhood on a fairly large Lustre filesystem.
We initially did a basic configuration with no policies or file
classes just to get robinhood working. We are now starting to try to
add policies, but not having any luck getting it to work. I added the
following lines to the config file, in an attempt to create a very
simple test policy that just sends the output of ls (of all the files
of a user called "ricky") to a file:
|define_policy list_ricky { status_manager = basic; scope { type ==
directory and name == 'ricky' } default_action = cmd("ls -al >>
/tmp/ricky_ls.out"); default_lru_sort_attr = none; } list_ricky_rules
{ rule default { condition { creation > 15w } } } |
Hello Michael,
Not related to your issue, but this doesn't look what you want to do:
cmd("ls -al >> /tmp/ricky_ls.out");
Here you execute "ls -la" in robinhood current directory, probably '/'.
The action supposed to be per entry, so I guess you want to run
something like:
cmd("ls -ld {fullpath} >> /tmp/ricky_ls.out");
|DB schema change detected: field 'ENTRIES.list_ricky_status' must be

I ran the command |robinhood --alter-db|, which took about 7 or 8
minutes to finish, but it failed with the following errors:

I don't know what this "Got error -1 from storage engine" means. Never
saw it.
If you scan is not too long, you could try to drop the DB and rescan, so
it will recreate the DB schema.
Also do you really need to maintain a "list_ricky_status"?
If not, you can specify "status_manager = none" so it will no longer
need to change the DB schema.
I removed the policy lines from the config file in an effort to get
things working the way they were previously, but I get the same exact
errors. It tells me ACCT_STAT doesn’t exist, tries to create and
populate it and then fails. So at this time, I can’t even get robin
hood to start at all. Please help!
