No, it does not change anything. If you had RAID 0 you would have no way to recover save for backing everything up and starting over, or adding 2 more drives and becoming a RAID 0+1 set.
If you mark a drive as failed you will lose it as part of the array. If you lose the other drive, then you will lose the machine, as if you had only a single drive load set.
There will be a small overhead shift, as you will no longer incur the write penalty for RAID 1, but will also no longer get the read performance increase that RAID 1 provides.
What you are doing is this:
1) logically "failing" a drive, to stop the sync to the mirror
2) removing the formerly mirrored drive from the array to re-purpose.
You should do an mdadm --zero-superblock to the drive you have removed (AND ONLY to that drive). Then you should also fdisk it and change the partition types to the appropriate types, in case it was set as RAID. From there you can proceed to using the drive as any other drive.
I would strongly advise you make a system backup JUST in case, as any disk re-purposing can go wrong.

Hi
Can I add disks on the fly to extend the capacity of an existing RAID 5 volume?
It's created on a 4P Advanced SSA Raid Adapter.
I need to extend a volume group, so I figured it would be easiest to extend the "physical disk" which is a RAID5 volume.
Thanks. (1 Reply)

Hi everyone
I've just purchased a Sun T5120 server with 2 internal disks. I've configured hardware RAID (mirror) and as a result the device tree in Solaris only contains 1 hard drive.
My question is, how would I know when one of the drives become faulty?
