O meu ataque ao software mdadm está em risco de perda de dados ???
Meus dois novos dois discos RAID-1 em discos usb externos se comportam de maneira estranha.
Ambos foram bons e reconstruídos e cat / proc / mdstat mostrou
Every 10,0s: cat /proc/mdstat Mon May 2 20:38:33 2011
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md1 : active raid1 sde1[1] sdc1[2](F)
1953514432 blocks [2/1] [_U]
md0 : active raid1 sdf2[0] sdd2[2](F)
452462592 blocks [2/1] [U_]
unused devices: <none>
Depois, desmontei-os e desliguei os discos.
Mais tarde, liguei cada par ao mesmo tempo e o gerenciador de disco do gnome mostra "degraded".
Não funciona como eu suponho que funcione.
Eu preciso parar o ataque antes de desconectar os discos?
E agora?
O mdstat ainda está bem, como postado acima, sem recriação iniciada.
Eu não consigo montar os ataques, o sistema de arquivos aparece como desconhecido. (deve ser reiserfs)
