John Plevyak commented on TS-773:
---------------------------------
I checked in what I hope is the fix. The cplist code needs to be cleaned up
as it is not clear which counts are counting bytes/store blocks/disk volume
blocks.
WARNING: this fix required changing the disk structure which will result in a
cache WIPE!
> 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.
