Re: Storage Activation error Dumped during RHEL 6.6 Installation

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.
