Title: How to take out one of the RAID1 HDs and mount is to anoter linux computer?
Post by: curdegn on August 10, 2008, 10:16:16 AM: Hi,

My SMEServer7 is running on two SATA HDs in software RAID1 mode (automatic set up at installation). From other Linux software RAID1 I am used to take out one of the RAID1 HDs and mount it to another linux computer with the mount option ("-t ext3"). This gives me the possibility to access all the data, for example in case the RAID servers mainboard etc. is defect.
Now according my tests today, I was not able to do the same with my SMEserver. Take out one HD and mount it to another linux computer did not work: the fs-type was not recognized. I think this is because the SMEserver has a LVM on top of the software RAID, right? So what is a possible way to access the data on that disk?

Thanks
Curdegn

You do not need to mount the drive and copy data etc, you can just remove one drive and connect it to another server box in degraded RAID1 array mode, and that server will function as a replica of the server the drive was removed from.
You can then add another new drive and resync the array and voila, you have a fully configured and functional RAID1 server (with all apps installed) with a minimum of effort.
