DRBD nao funciona

Bom dia para todos,

Estou tendo o seguinte problema: configurei dois resource, drbd0 e drbd1. O primeiro monta e sincroniza perfeitamente, so que o segundo, /dev/nb1, referenciando /dev/hda5, que sera montado em /u01, esta me retornando a seguinte saida:

drbd: Operator forced primary status on drbd0 (/dev/nb0)
[1]+ User defined signal 1 ( $DRBD_SETUP $device wait_connect -t $timeout )
drbd: Operator forced primary status on drbd1 (/dev/nb1)
[1]+ User defined signal 1 ( $DRBD_SETUP $device wait_connect -t $timeout )
drbd: ERROR: drbdsetup /dev/nb1 primary --human [21]:
drbd: ERROR: ioctl() failed: Input/output error
Local replica is inconsistent (--do-what-I-say ?)
drbd: 'drbd0' still not in Connected state, but WFConnection
drbd: 'drbd1' still not in Connected state, but WFConnection
NEEDS_SYNC INCONSISTENT
Ja verifiquei as configuracoes, reinstalei o DRBD, mas nao consigo achar o problema. Alguem poderia me ajudar? Desde ja, agradeco.
