The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Linux - sdb : very big device. try to use READ CAPACITY(16)

Asked by CrazyDon in Linux Setup

Tags: read, big, very, use, try

Hi,

We have a fileserver that has a raid 5 on a 3ware raid card. One of the partitions filled up and we decided to increase the size of the filesystem by replacing all of the 320gig drives with 750gig drives. The array is rebuilt with the new drives for 4.2 tb of storage.

When I reboot linux, the following is put into the system log.

SCSI device sdb: 8788930560 512-byte hdwr sectors (4499932 MB)
sdb: Write Protect is off
sdb: Mode Sense: 23 00 00 00
SCSI device sdb: write cache: enabled, read cache: disabled, doesn't support DPO or FUA
sdb : very big device. try to use READ CAPACITY(16).
SCSI device sdb: 8788930560 512-byte hdwr sectors (4499932 MB)


Shouldn't linux be able to see an ext3 filesystem  bigger then 4tb. This is the 32-bit version of centos, so would this problem go away if I went to the 64-bit centos version?. This is an Intel P4/Xeon, so if I need to move to the 64-bit version, would I use the ia64 or the x86_64 version of centos?
