RAID 1に3つのSSDドライブを備えた専用サーバーがあります。cat/ proc/mdstatの出力:
Personalities : [raid1] [linear] [multipath] [raid0] [raid6] [raid5] [raid4] [raid10]
md4 : active raid1 sdc4[2] sdb4[1] sda4[0]
106738624 blocks [3/3] [UUU]
bitmap: 0/1 pages [0KB], 65536KB chunk
md2 : active raid1 sdc2[2] sda2[0] sdb2[1]
5497792 blocks [3/3] [UUU]
md1 : active raid1 sda1[0] sdc1[2] sdb1[1]
259008 blocks [3/3] [UUU]
unused devices: <none>
aドライブをソフトRAIDから安全に削除するにはどうすればよいですか失うことなく任意のデータ?最も重要なデータをミラーリングしたまま、ドライブをアレイから取り外して再フォーマットし、独立して使用したいと思います。
前もって感謝します
man mdadm:
-r, --remove remove listed devices. They must not be active. i.e. they should be failed or spare devices. As well as the name of a device file (e.g. /dev/sda1) the words failed, detached and names like set-A can be given to --remove. The first causes all failed device to be removed. The second causes any device which is no longer connected to the system (i.e an 'open' returns ENXIO) to be removed. The third will remove a set as describe below under --fail.
