Hi all, I have one drive fails on a software 2TB RAID1. I have removed the failed partition from mdraid and now ready to replace the failed drive. I want to ask for opinion if there is better way to do that other than: 1. Put the new HDD. 2. Use parted to recreate the same partition scheme. 3. Use mdadm to rebuild the RAID. Especially #2 is rather tricky. I have to create an exact partition scheme. Can I just clone the partition table without the data in it using parted? How? Thank you, Fajar.

Use mdadm to rebuild the RAID.Thanks Markus, But I see this: DESCRIPTION sfdisk has four (main) uses: list the size of a partition, list the partitions on a device, check the partitions on a device, and - very dangerous - repartition a device. sfdisk doesn't understand GUID Partition Table (GPT) and it is not designed for large partitions. In particular case use more advanced GNU parted(8). Is it ok?
