Description Qian Cai 2011-03-08 02:45:25 UTC 
Description of problem:
There is currently a limitation,
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html-single/5.6_Technical_Notes/index.html#id2194456

"4 kilobyte physical sectors, 4 kilobyte logical sector harddisks
    4 kilobyte physical sectors, 4 kilobyte logical sector harddisks require firmware and software modifications to function. This type of 4 kilobytes sector disks is currently not supported in Red Hat Enterprise Linux 5"

However, there is an USB 3.0 storage device (3T in size) but found it is not working in RHEL5 due to its 4k logical sector size (not even been able to make partitions). Since there were a couple of BZs to support new systems with USB 3.0 controllers (running in 2.0 mode) have been approved in 5.7 already. Suspect that it is going to cause support issues afterwards when customers are starting to use USB 3.0 devices for 5.7.

Version-Release number of selected component (if applicable):
parted-1.8.1-27.el5

How reproducible:
always

Steps to Reproduce:
# parted /dev/sdb
Warning: Device /dev/sdb has a logical sector size of 4096.  Not all parts of GNU Parted support this at the moment, and the working code is HIGHLY
EXPERIMENTAL.

GNU Parted 1.8.1
Using /dev/sdb

Comment 2 Dave Cantrell 2011-08-18 21:27:38 UTC 
This needs to be a known limitation of RHEL-5.  The code to support 4K logical sector size disks in parted is upstream and should, if it hasn't already, make its way in to RHEL-6.  We are unable to backport this to RHEL-5, the only option is to rebase parted.  And that's something we cannot do this late in the RHEL-5 stream.
