DUO, Flex-RAID 0, Replace disk 1
Hi I got 2 disks and running Flex-RAID 0. The first disk (C) is giving up on me and alot of SMART errors are in the log. If I wanna replace the disk can I do this? * Copy all data to a windows ...
I know that. I was talking about the OS (Operating System) partition being RAID-1 not the data volume.
Here's some info I get from my Duo v2 running Flex-RAID
As you can see the OS partition (/dev/md0) and the swap (/dev/md1) are raid-1 (mirrored across the two disks). The data volumes C (/dev/md2) and D (/dev/md3) are RAID-0 (i.e. no redundancy).
The Duo v1 though a very different product to the v2 would also have a redundant OS partition (in the Duo's case 2GB). So if you replace a disk the OS partition will be synced onto the replacement.
