I have a dedicated server with 3 SSD drives in RAID 1. Output of
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10] md4 : active raid1 sdc4 sdb4 sda4 106738624 blocks [3/3] [UUU] bitmap: 0/1 pages [0KB], 65536KB chunk md2 : active raid1 sdc2 sda2 sdb2 5497792 blocks [3/3] [UUU] md1 : active raid1 sda1 sdc1 sdb1 259008 blocks [3/3] [UUU] unused devices: <none>
¿How can a drive be safely removed from the soft raid without loosing any data? I would like to remove a drive from the array in order to reformat it and use it independently, while keeping the most important data mirrored.
