Converting Raid 0 to Raid 5 1

[AussieCandii]

Hi

For some unknown reason, after a recent disk failure, our raid array reconfigured itself to Raid 0 from Raid 5. I now have a Raid 0 array with 5 disks instead of a Raid 5 array with 6!!

Can I convert the array without having to rebuild the entire server and restore all the data? If not, how do I go about rebuilding the PDC and still keeping my network up??

HELP

Thanks

Assuming you are not talking about the system or boot partitions and are talking software RAID for your data, you can "simply" delete the partitions of the RAID 0 set and create a new RAID 5 set. Having destroyed everything, you will need to restore from tape though - no way round that.

Until you do that, you are risking your data - one disk down, everything gone.

Unfortunately for me, whoever built this server installed the OS on the RAID set - together with the data - so once I recreate the array, it's all gone, OS and data and the server has to be rebuilt from scratch ..... ho hum, just another day at the office!

Is it a hardware or software RAID? You can't build NT on softRAID so I guess it is hardware. If hardware has converted to RAID 0 go to the BIOS - if it didn't destroy it going one way, you might be lucky... (doubt it).
