ATS thinks 1GB disk is too small
Using ATS v5.3.2, I have a 1GB virtual disk configured (via OpenStack) as /dev/sdb. This is the only disk in my volume. There are a few other disks in another volume, but I’m not troubleshooting those yet.
When I start ATS, I see the following in diags.log:
[centos@beta1-edge2 ~]$ tail /opt/trafficserver/var/log/trafficserver/diags.log
[Jun 8 20:27:05.327] Server {0x2b702a726700} WARNING: the size of volume 1 (0) is less than the minimum required volume size 128
[Jun 8 20:27:05.327] Server {0x2b702a726700} WARNING: volume 1 is not created
[Jun 8 20:27:05.328] Server {0x2b702a726700} WARNING: failed to initialize the cache for http: cache disabled
[Jun 8 20:27:05.328] Server {0x2b702a726700} NOTE: cache disabled
Is any special action needed to get ATS to recognize and begin using the disks?
Thanks!
Eric

Hmmm ... can you try again with "traffic_server -T cache" to capture more debug tags? Can you also file a Jira <https://issues.apache.org/jira/browse/TS> and attach a storage.config and volume.config that reproduces?
thanks

Thanks James-
Looks like it detected the drive size properly, however the cache init is still failing. I removed the /dev/ram* devices from storage.config just in case they were causing a problem. I also added another 4GB virtual drive just to see if more disk space was needed.

It sounds like ATS wasn't able to probe the geometry for that volume. Can you run "traffic_server -T cache_init" and see what size it detected?
