I have a Seagate 750GB drive.
Parted shows the drive as 750GB
parted /dev/sdc print Model: ST375064 0AS (scsi) Disk /dev/sdc: 750GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 17.4kB 750GB 750GB ext3 primary
However, the size entry in
/proc/partitions is supposedly in blocks:
cat /proc/partitions major minor #blocks name 8 32 732574584 sdc
Parted says the block size is 512B,
blockdev --getbsz /dev/sdc says the block size is 4096.
But… it is clear that
/proc/partition is wrongly reporting the device size in KiB rather than blocks.
Can this behavior be depended on across Linux and/or kernel versions? (I need a scriptable and consistent way of finding the size of a block device)
Centos 6.6 with 3.10 kernel.
