Does anyone here use software RAID on Linux?
soult: I am using RAID1 on my PC and RAID0 on some servers, all software raid with mdadm. I never had any problems temporarily removing one HDD from the array (when I needed some free space for a short time) and resyncing it again, but I always marked the drive as faulty (mdadm --manage /dev/md0 --fail /dev/sdb2) and then removed them (mdadm --manage /dev/md0 --remove /dev/sdb2) before re-using it.Resyncing the array is just as simple: Partition the disk, create a partition that is the same size as the other RAID1 partition and re-add it to the array (mdadm --manage /dev/md0 --add /dev/sdb2)
