Hi, Greg, The log is generated by ceph service at runtime.
Even I change the permission, it would be overwritten by the service someday. I am afraid if there is any other permission problem when I execute other commands. Ex: I need to modify more files' permission Ex: The library use any API in kernel space. Anyway, thanks for your reply, I will try to modify the two files' permission first. regards, Eric/Pjack -----Original Message----- From: Gregory Farnum [mailto:[email protected]] Sent: Thursday, November 03, 2011 12:49 PM To: Eric YH Chen/WHQ/Wistron Cc: [email protected] Subject: Re: Cannot execute rados.py with sudoer This looks like your standard permissions issue to me. The keyring and log were probably created by mkcephfs running under sudo? But if you give your current user the ability to read/write from them everything should work fine. -Greg On Wed, Nov 2, 2011 at 8:55 PM, <[email protected]> wrote: > Hi, all: > > When I use raods.py, I met some problem even if the user is in sudoer. > I found it would access /etc/ceph/client.admin.keyring and > /var/log/ceph/client.admin.log which is only available to root. > Do you have any suggestion?
