Hello,
I started using OMV recently and have a question regarding RAID on LVM logical volumes.
I installed Debian 6.0.9 and the followed the very good installation guide http://forums.openmediavault.org/viewtopic.php?f=12&t=2140
I think this might be more of a debian problem but I still hope somebody can help me.
I have 4 drives (2* 2,5 TB and 2*3 TB) and I want to create a RAID 5 on them.
I can't do it directly because the size differs and I would loose the additional storage on the larger drives.
After I installed the lvm plugin I can create logical volumes with identical size and create a 4 drive RAID 5 and put the additional space on the larger drives into another RAID 1.
It all works fine until I reboot.
After reboot the RAID is gone. It is not listed in RAID Management and the file systems are listed as missing.
The RAID can be restored manually by running
and the RAID is listed under RAID Management as clean again.
I then have to manually mount the filesystem and everything is fine again. The data stored is available.
I think the problem is that during boot when the system looks for RAIDs LVM might not be available, but this is just a guess.
Is there any way to automate the assemble and mounting?
