Hi all,

a question about maintenance reservation. The ` pbs_rsub` man page tell that you type something like (as root on the PBS primary)

```auto
pbs_rsub -R <start> -E <end> --hosts host1 host2

```

however when I try this I get

```auto
Bad effective UID for reservation

```

note that I can create reservations as a user (albeit I am still unsure about confirming them); adding `-u`  
or `-U` options does not help. I have `set server flatuid = True`.

What I am doing wrong?

Addendum: i become root with either `sudo -i` or `sudo -s` I cannot do `su`; btw doing `sudo pbs_rsub ...` yields the same result.

If you would like to set a maintenance reservation as root user.  
`qmgr -c "set server acl_roots=root"`  
Caution: root can run jobs on the cluster now .

Hi Adarsh,

thank you for your reply. I tried with root because running

```auto
pbs_rsub -R x -E x+y --hosts host1 host2 

```

run as a user yielded

```auto
pbs_rsub: Unauthorized Request

```

on the other hand, executing the command as root bu tyring to assign the reservation to another user with `-u`, `-U` (or both) still gave `Bad effective UID`. So I am a bit confused regarding who would the best user to create manteinance reservations and how.

Thank you

Hi @tuthmose, you need to be an operator to set maintenance reservations. You can set operators via qmgr.
