Leif Hedstrom commented on TS-4465:
-----------------------------------
This is on the filesystem ? We'd have to ask [~amc] to check this, but we
definitely don't recommend this setup. For such a large disk, you really should
be using the raw device.

> I tried it with several sizes. I can create cache.db with max 1600GB.
> Anything bigger results in the cache being disabled (log above). It actually
> creates the file with the mentioned size, file permissions are ok but it
> always complains that "disk header different for disk
> /data/trafficserver/cache.db: clearing the disk" and "failed to initialize
> the cache for http: cache disabled".
> Strange thing is that we use the same version on other servers where we
> upgraded an installation from a previous version. cache.db file already
> existed and this is working fine.
