[RESOLVED] Problem creating raid5

borry · 10. Mai 2013

Hi there,

I'm new here and have some problems with creating a raid 5 array on my system.

I've installed omv 3 on my old thecus n5200 nas.
I've got 5 2Tb sata disks (4 samsung f4 ecogreen 204HDUI, 1 seagate/samung f4 ecogreen 204HDUI).
After installing , OMV recognizes all disk under physical disks.
But when try to build a raid, the only drive i can select is the seagate drive.

Same thing happens when i choose to build a filesytem.
I can only select the seagate drive.

I already tried to upgrade the firmware of the samsung drives but these already have the latest firmware.

Help needed, because i'm clueless

You should no longer use omv .3 (only if you need some plugins that are only working at .3), update to .4 and lets see if the problem is persistent.

Greetings

Assuming you don't have data on them, try using the wipe button in the Physical Disks tab.

Version 4 didn' t install on the thecus.
After reading the forums i think the serial port could be the problem.
I will try disabling the serial port and see if version 4 installs.

you don't have to reinstall. Change the repository to fedaykin after that make an apt-get update and apt-get upgrade or apt-get dist-upgrade

I've updated from 0.3 to 0.4.28, no change.
I still can't use the samsung drives.

I've tried the wipe button (fast wipe).
Got a message about changing the mbr but still no change.

The OMV version wouldn't matter. Make note of the drives not showing up and their letters (like /dev/sdc). Try the following as root. Substitute X with the letter noted previously.

Code

mdadm --zero-superblock /dev/sdX
parted /dev/sdX mklabel msdos
dd if=/dev/zero of=/dev/sdX bs=512 count=100000

Great
I can now select the drives, raid 5 build is in progress.

Big thanx.

Hi.
Just bumped in to this thread. I'm about to replace all drives in my n5200 an have been a happy user of omv on a HP micro server. How did you install omv on the Thecus? Any links or reference?
Thanks.
