Raid 1 to Raid 5

Recommended Posts

Hello everyone.

 

I have setup a XPenology box using a M/B asrock q2900-itx, 2x WD Red HDD 2 TB in raid 1 configuration, XPEnoboot 5.1-5022.3 and latest DSM 5.1 update 4.

 

I bought another 2x WD Red HDD 2 TB and i want to change the raid type to raid 5.

 

When i choose Manage --> Change raid type and select the raid 5 option at the storage manager, nothing happens.

 

This is the logs from var/log/messages:

If I were you I would transfer your data to one of the new drives... build a SHR-1 with 3 of the drives... transfer your data on the new drive to your SHR-1 and expand the SHR-1 with the 4th disk...

Since Raid 1 is a mirror you might be able to skip the transfer to a new drive and just use one of the mirror disk...

 

there might be better ways to do this... But personal I would do it this way...
