[FUG-BR] FreeBsd 8.2 e geom_stripe

Sábado Agosto 13 22:46:58 BRT 2011

Olá pessoal !!
 Estou usando "GPT" no FreeBSD para criar partições grandes e em conjunto
com o gstripe criei vários slices em dois hds distintos para juntar todas
ganhando um maior armazenamento!

Para meu HD ad5

E para o meu HD ad6 onde está o SO BSD ainda usando o scheme MBR portando
particionar até 4 ...

Agrupei todas com o mesmo tamanho ...
gstripe label -v st0 /dev/ad5s1 /dev/ad5s2 /dev/ad5s3 /dev/ad5s4 /dev/ad5s5
/dev/ad5s6 /dev/ad5s7 /dev/ad5s8 /dev/ad5s9 /dev/ad6s2 /dev/ad6s3 /dev/ad6s4

estou subindo com o meu sysctl :
kern.geom.debugflags=16
kern.geom.label.gptid.enable=0

O módulo geom_stripe está subindo no loader.cf

Apos formatar montei minha partição sem problemas:
mount /dev/stripe/st0 /backup

até ae tudo funcionando df -lah

/dev/stripe/st0    3.3T    4.0K    3.0T     0%    /backup

 Tenho 3.3 Teras montados e funcional...

O problema são os logs após o boot:

Tudo continua funcionando tranquilamente, mas fiquei pouco confiante de
colocar algo em produção com estes erros todos, alguem sabe me informar o q
