Users / Re: Raid help
« on: December 22, 2009, 06:14:35 pm »

Regarding your first question I believe that it could depend on a number of this but if I should guess most likely not all disks has been included in the raid. Check with mdadm command wich disks have been included and verify that the raid is ok. I would recomend to set up the new raid array trough linuxmce webadmin, then you can monitor the progress and see if something goes wrong during the setup.

Regarding your second question: I managed to bring up an already created raid array when reinstalling lmce 810 from scratch. I first installed kubuntu 8.10 and then activated the raid with the command "sudo mdadm --assemble --scan", the raid device was then visible in the /dev directory.  I then installed linuxmce and the raid array was automatically detected.

I do not know if this could be of any help, but I hope you manage to get your raid up and working again.

Good luck.

Best regards

How about you guys bring your thoughts together and figure out how to fully implement zfs with LinuxMCE...

It would be nice to have zfs working in linuxmce. I would foresee that the the functionality could be very similar to creating a raid device today (including functionality so the zfs pool would be mouned automaticaly to the file system).

Some thoughts besides the issue of expanding the zfs pool as prevoisly mensioned:
  • Fuse (that implements zfs in linux) runs in user space which I do not know if this might be a issue.
    To take the full benefits of ZFS it should be run on a 64-bit operating system I do not know if linuxmce 810 will be released on Kubuntu 64-bit ?

Otherwise my experience of manageing the zfs pools is quite straight forward (on a basic level) and fuse was easy to install with debian packages in kubuntu 8.10.

Goku thanks for the explanation seems that you found a way to handle the mounting. I was struggeling with the export files on the core and the fstab files on the md but your way seems to be much better.

Hi Viking,

Thanks for the clarification and workaround to see the raid in the mnt directory again. I just wonder if it might effect the raid negatively to be mounted/unmounted so frequently ?

Best regards

Very interesting concept. Are you using ZFS with LMCE810? Should this be implemented before loading LinuxMCE or can it be after?

no i was using zfs in 710 and the older vers. you will have install zfs after installing linuxmce.


I was using ZFS in 810 i.e. created the ZFS pool in kubuntu and mounted it manually to the file system used by my LinuxMCE core. However I never managed to get my LinuxMCE core to recognize it in the same way as it does with raid and mounting the ZFS pool manually was not a solution that allowed me ta take the benefit of the LinuxMCE solution and work in the long run.
So I am now using raid instead of zfs, most likely this was due to my limited knowledge of LinuxMCE.
I really liked ZFS and it would be very nice to use it again so if you have any sugestions on how the ZFS pool can be configured to work with LinuxMCE it would be very much appreciated.

Thanks for the response. I only put 1 HD in to see if it would reconize it and let me use it. I have check the reconfigure device and tried restarting. I have not been creating my raid then letting LCME find it. LCME created my raid for me. The raid I had in my machine came from my 710 box and worked great every time I put back in the 710 box. I broke the raid apart in hope that 810 would build it correctly.

Has anyone got 810 to use a HD correctly. I would like to use Raid0 just for the large space. Any help would be great and if anyone else is having problems post here and let see what is going on.


I have some (limited) experiences with RAID in lmce 810.
I managed to create a raid 5 system consisting 4 1TB disks by using the LMCU GUI. Initially I faced som problems since one of the disk had a bad sata cable which prevented me to buils the raid.
After replacing the faulty sata cable I could build the raid sucesfully and LINUXMCE created the filesystem and mount points (i.e. /home/public/data/video, audio etc) to the raid.
It seems to be working ok to some point but I have some issues for instance the raid is not always visible in the /mnt/device/ directory and when I ran the e2fsck command on the raid it stated that the raid had been mounted more then 4000 times during the past month, which leeds me to believe that it is constantly beeing mounted/unmounted by my lmce setup.

By looking at your screen shots I believe that you should "tick" the box "Use Automatically" that will most likely do that your raid is mounted and you could start to use it, since it seems that your raid has been created sucessfully.

It would be intresting to know if this would help, aswell if you experience the same issue as I have with the raid constantly beeing mounted/unmounted.
