Xenserver software raid 5

At this stage you will have raid1 with only disk. SDB: 1 4. What about partition table, is md looks healthy? Could you comment on this? Use GNU Parted.

To prevent this, create the devices as describbed in this tutorial, but before copieing the files, run the mdadm scan eg.

If you extract from the chrooted location, the mdraid driver will not be included and you will get some nice kernel panics when trying to boot :.

The default metadata version 1. Editing the init file inside initrd The init file does not contain any raidautorun lines by default but instead uses mdadm.

This may be resurrecting the dead, but my installation does not have the third partition, so upon creating I receive this error…. I am not sure where to go with this at the moment.

Thanks for your help, and if you could explain the steps it would be awesome, since I am just learning Linux. Comment by Jorge Zamit — September 23, pm. But then I rebooted the physical server to move it, and that was the last time it booted.
