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.

Setting up gvinum raid5 on FreeBSD 7 ( amd64 )

Asked by achaean1 in FreeBSD, Unix Operating Systems, BSD Unix

Tags: , , ,

Hello, I'm trying to get gvinum raid5 running on FreeBSD 7 and have hit a road block, here's the run down.

I have an IDE HD ( 200gb ), which has the freeBSD install on it and 4 500GB hard drives ( exact same hard drives ) connected via sata2. I have thoroughly tested all 5 hard drives on other systems and they are all good.

After installing freeBSD I did the following

1) BSDLABELS

#bsdlabel -w /dev/ad4
#bsdlabel -w /dev/ad5
#bsdlabel -w /dev/ad6
#bsdlabel -w /dev/ad7

3) created my raid config file "/etc/raid.conf"

drive disk_1 device /dev/ad4
drive disk_2 device /dev/ad5
drive disk_3 device /dev/ad6
drive disk_4 device /dev/ad7
volume raid5
plex org 261k
sd drive disk_1
sd drive disk_2
sd drive disk_3
sd drive disk_4

3) Created the array

#gvinum create /etc/raid.conf

4) Partitioned the new array

#newfs /dev/gvinum/raid5

5) Created Directory and Mounted it

#mkdir /wmfiles
#mount /dev/gvinum/raid5 /wmfiles

And voila , the volume, plex, and subdisks were running and I could write to wmfiles perfectly fine.

I then add the new mount to fstab

/dev/gvinum/raid5                /wmfiles                 ufs                  rw                 2                 2

and add it to the /boot/loader.conf

geom_vinum_load="YES"

-------------------------------------------------------
Here's where things go wrong, I reboot and the boot fails because of the new volume. It throws the following error and puts me into a crippled single user mode where I must remount /usr, /, and /var just to use my /rescue/vi

THE FOLLOWING FILE SYSTEM HAD AN UNEXPECTED INCONSISTENCY:
        ufs: /dev/gvinum/raid5 (/wmfiles)
Automatic file system check failed; help!

when I run

#fsck /dev/gvinum/raid5

I get

CANNOT READ BLK: 128

which seems to be the first block, followed by ( after continue )

THE FOLLOWING DISK SECTORS COULD NOT BE READ: 128, 129 [etc etc] 142, 143,
ioctl (GCINFO): Inappropriate ioctl for device
fsck_ufs: /dev/gvinum/raid5: can't read disk label

#gvinum list

returns that the volume and plex are down and the subdisks are stale, if I remove the fstab line and the loader.conf line, and reboot, then try to mount and start the volume manually, nothing happens.

Anyone have any ideas as to how to fix this? I am a relative UNIX newbie, so please tell me exactly how to do something if you'd like more information ( ie if you ask for a config file print out etc, tell me how to get said printout, thanks )
