HI, I've made a RAID1 over two sata drives using MD and one partition on each device. I use etx3 on the resulting md device (/dev/md0). I used a tool to size the partitions to avoid having to guess the maximum sizes, but I wanted to make sure I could write to the entire filesystem and so I used dd to make a big file : sudo dd if=/dev/zero of=bigfile bs=1024K count=500M This resulted in a somewhat predictable : dd: writing `bigfile': No space left on device 472433+0 records in 472432+0 records out 495381721088 bytes (495 GB) copied, 8204.09 s, 60.4 MB/s However, it also resulted in : Jul 25 17:37:42 jeeves mdadm: Rebuild60 event detected on md device /dev/md0 and md is dutifully rebuilding it. Clearly, this concerns me. Could someone enlighten me as to what went wrong (if anything)? Is there a better way to test the file system and partition/drive are writable in their entirety? Thanks, Max.
