Using Debian RAID1 with mdadm and NTFS offers improved performance!
Attempting to configure a new RAID1 setup and evaluating different failure situations has been quite challenging. What makes ext4 more complex than NTFS with mdadm RAID1? When using NTFS, both drives were formatted to NTFS and then the RAID array was created successfully. After that, running ntfsfix on the array resolved issues, allowing normal operation even if metadata was damaged or if the drive needed to be accessed elsewhere. With Ext4, formatting to ext4 didn’t fix the problem; I couldn’t mount the RAID array directly due to size mismatches, so a new partition had to be created. If corruption occurs, repairing RAID or recovering data becomes time-consuming. Why is ext4 much simpler in Linux compared to other systems? Or am I making mistakes during the process?
Yes. Setting up the RAID and then creating partitions or filesystems is the proper method. The approach you took means part of the filesystem will have been altered or erased, relying on NTFS to recover from backup copies of its metadata. It remains somewhat unstable and could fail at any moment.
