Hello guys, I have a problem with mdadm. I created three partition ( swap, / , /home) and I have configured swap in raid0 and /home in raid1. When I configure in raid1 / with mdadm, the system return this message: mdadm: super1.x cannot open /dev/sda2: Device or resource busy mdmon: ddf: Cannot use /dev/sda2: Device or resource busy mdmon: Cannot use /dev/sda2: It is busy mdadm: cannot open /dev/sda2: Device or resource busy cat /proc/mdstat Personalities : [raid0] [raid1] md1 : active (auto-read-only) raid1 sdb2[1] 15351808 blocks super 1.2 [2/1] [_U] md2 : active raid1 sda3[2] sdb3[1] 226609152 blocks super 1.2 [2/1] [_U] [=====>...............] recovery = 29.4% (66639232/226609152) finish=924.9min speed=2882K/sec bitmap: 2/2 pages [8KB], 65536KB chunk md0 : active raid0 sda1[0] sdb1[1] 4190208 blocks super 1.2 512k chunks How I can fix?
