--------------------------------

             Summary: Raw disk cache device permissions being bypassed
                 Key: TS-2399
                 URL: https://issues.apache.org/jira/browse/TS-2399
             Project: Traffic Server
          Issue Type: Bug
          Components: Cache, Core
            Reporter: David Carlin


raw disk cache device permissions:

{noformat}brw-rw---- 1 root disk 253, 4 Nov 26 16:03 /dev/dm-4
{noformat}

If I run 'traffic_server' by itself, I can't use the cache - I get permission errors opening it up:

{noformat}
[Nov 26 16:56:42.976] Server {0x2b4e29878540} WARNING: unable to open '/dev/dm-4': -13, Permission denied
[Nov 26 16:56:42.976] Server {0x2b4e29878540} WARNING: could not initialize storage "/dev/dm-4" [unable to open]
[Nov 26 16:56:42.976] Server {0x2b4e29878540} NOTE: cache clustering disabled
{noformat}

However, I can I start ATS fine and use the raw disk cache via the trafficserver startup script.

These docs indicate that I should be setting the owner to the user that ATS runs as, but I don't need to as long as I start via the script:

Once I change ownership of /dev/dm-4 to nobody then I can launch traffic_server by itself.
