Re: Storage Activation error Dumped during RHEL 6.6 Installation

[anant garg <garginfo158@xxxxxxxxx>]

Hi All,

Does anybody knew about the above behavior of RHEL6.6  Installer.

Please help if you have information about the above behavior.

Also i investigated more from anaconda program.log  and found that command( mdadm asemble) has failed from anaconda mdraid's mdactivate function :-

Below is snippet from anaconda progrm.log :-

02:01:53,585 INFO : Running... ['mdadm', '--assemble', '/dev/md8', '--uuid=1a09565d:1e048978:ab559ea5:c7753fbf', '--run', '--auto=md', '/dev/sdb1', '/dev/

sdl1']
02:01:53,589 ERROR   : mdadm: no recogniseable superblock on /dev/sdb1 

02:01:53,589 ERROR : mdadm: no recogniseable superblock on /dev/sdl1

I doubt how a reboot(2-3 times) and then try installation makes the above problem solve.

Please feel free to contact me in case you need more information.

Please help me if you have information.

Hi All,

Greetings for the day.

I have some servers which I used occasionally for Installation.

I was performing RHEL6.6 Installation on  a server.

While installation, I saw error of below title:-

An error was encountered while activating your storage configuration

mdactivate failed for /dev/md8: 02:01:53,589 ERROR   : 

mdadm: no recogniseable superblock on /dev/sdl1

I checked the exception report, It says below:-

MDRaidError: mdactivate failed for /dev/md8: 02:01:53,589 ERROR   : mdadm: no recogniseable superblock on /dev/sdl1

I checked the system but  found that /dev/sdl1 was accessible normally.

Also when I reboot system two-three times and then start Installation this problem does not occurs.

So This problem does not always occur, but occurs very frequently.

Does anybody have an Idea to fix it. Please help in such case 

Please let me know if you need more information .

Thanks and Regards,

Anant Garg
