John Plevyak commented on TS-773:
---------------------------------
Well, I did predict failure :) In this case the problem was that the directory
can now be more than
2GB in size, which exceeds an 'int'. The resulting patch touched lots of the
system because it also means
we can now read and write > 2GB in a single go. I have submitted a patch and
tested in a faked disk over 2TB
(I had Store.cc lie about the size of the disk). Give it a go.
> Traffic server has a hard limit of 512 gigabytes per RAW disk partition

> Key: TS-773
> URL: https://issues.apache.org/jira/browse/TS-773
> Project: Traffic Server
> Issue Type: Bug
> Components: Cache
> Affects Versions: 2.1.8
> Environment: Debian Lenny 5.0.8 2.6.34.7 x86_64
> 12 1.5TB harddrives for cache disks.
> Reporter: David Robinson
> Assignee: John Plevyak
> Fix For: 2.1.9
>
>
> Using 1.5TB harddrives as cache disks results in ATS only using 512GBs of the
> disk. The disks are configured in RAW mode with no partition information.
> storage.config is setup like this,
> /dev/sda
> /dev/sdb
> /dev/sde
> /dev/sdf
> /dev/sdh
> /dev/sdi
> /dev/sdj
> /dev/sdk
> /dev/sdl
> /dev/sdm
> /dev/sdn
> /dev/sdo
> fdisk -l /dev/sdo
> Disk /dev/sdo: 1500.3 GB, 1500301910016 bytes
> 255 heads, 63 sectors/track, 182401 cylinders
> Units = cylinders of 16065 * 512 = 8225280 bytes
> Disk identifier: 0x00000000
> Partitioning a disk into 3 512G partition and adding then to storage.config
> will make ATS use the entire 1.5TBs of space.
