Eu tenho problemas ao tentar recarregar alguns dispositivos multipathed após atualizar um servidor linux. de alguma forma, os metadevices mudaram de / dev / md1 para / dev / md127.
então eu tenho esses problemas:
# multipath -v 2 -r

alguma ideia do que poderia ser o problema ... a invasão está atualmente degradada porque os dispositivos desaparecem ou mudaram

originalmente nós não criamos este ataque, criamos o seguinte:
mdadm --create --verbose /dev/md1 --level=1 --raid-devices=2 /dev/mapper/mpathaxp1 /dev/mapper/mpathayp1
então estou perplexo como isso se tornou / dev / 127 com apenas um disco ..
obrigado
