Storage on FreeBSD (file and raw device issues)

Hi All.

I'm working on optimization of our CDN, and ATS is looks like a solution
that can fit our requirements.
But I'm in stuck at the moment :(

Trying to make work trafficserver-3.0.5 (from the ports tree) on FreeBSD
9.1, but I found, that I can't create storage more that 1.5Tb (while I need
much larger storage ~50Tb if it's possible with ATS at all)

Got message:

[Nov 30 16:16:23.669] Server {34418534400} WARNING: cache disk operation
failed WRITE -1 22
[Nov 30 16:16:23.714] Server {34418512896} WARNING: unable to clear cache
directory '/cache/trafficserver/cache.db 589824:393207737'
[Nov 30 16:16:23.715] Server {34418513920} WARNING: failed to initialize
the cache for http: cache disabled
[Nov 30 16:16:23.715] Server {34418513920} NOTE: cache disabled
[TrafficManager] ==> Cleaning up and reissuing signal #15

If I set storage for example 1Tb everything work as expected without
warnings.

Tried to use raw device as storage, and got message "Currently Raw Disks
are not supported":

[Nov 30 16:57:07.928] Server {34418488320} WARNING: Currently Raw Disks are
not supported
[Nov 30 16:57:07.928] Server {34418488320} WARNING: could not initialize
storage "/dev/da0" [Currently Raw Disks are not supported]
[Nov 30 16:57:07.928] Server {34418488320} NOTE: cache clustering disabled

If I missed the same thread, where the same issue was solved, please point
me on that.
Any help will be very appreciated.
Thanks in advance.

Any ideas about incorrect calculation of cache-file?

n.b.: I have not tested this code with ZFS as provider for the
RAW disk, and I've only tested a meager 1G - which is all my
Laptop has..

I'll try to increase the (usefulness) of the debugging in the
area, and hope you can help me gain more insight.

Hi,
I've created 3Tb zfs raw device, and got below messages:

After I've changed it to cache-file with size 1024000M, file with
strange size 15T was created.

# ls -lh /cache/trafficserver/
-rw-r--r--  1 nobody  www    15T Dec  3 10:26 cache.db

And got the same issue:

BTW, if I set cache-file size to 102400M then 1.6T cached.db created,
1024M = 16G etc.

\o/

Awesome. Your feedback is very appreciated. I have proposed this
patch for the next stable release, but haven't had the opportunity
to extensively test it myself

Re: Storage on FreeBSD (file and raw device issues)

Posted by Vladyslav Bachynskyi <v....@gmail.com>.
I have already built the 3.3.1 dev version under FreeBSD and added the 
raw (zfs) disk to storage.config.
All looks good at the moment, but full testing I'll be able to make in 
Monday at job.

Thanks,

Igor added FreeBSD raw disk support recently, but I don't think that's in any released version. Can you build master from git://git.apache.org/trafficserver.git and test that?
