----- Mensagem encaminhada de gust...@z ----- Data: Fri, 20 Mar 2009 12:46:43 -0300 De: gust...@z Assunto: Re: [FUG-BR] Kernel panic STABLE 7.0 Para: Ari Confirme se as panic strings são iguais mesmo. No meu caso aparentemente foi um problema no sistema de arquivos devido aos caras do datacenter terem desligado a máquina na marra. Eu sugiro que vc cheque se for o mesmo panic string, quais as partições afetadas, passe fsck na mão e acima de tudo DESABILITE fsck em background pois ele só dá dor de cabeça, não parece funcionar... (vc pode fazer isso pelo rc.conf, background_fsck="NO" ) estou na correria agora se me ocorrer alguma idéia entro em contato. abraços --gustavo Citando Ari : > > > 2009/3/12 <gust...@z> > >> Estou com um FreeBSD aqui num Dell Poweredge R200 que me deu uns >> kernel panics, eis as panic strings: >> >> Code: >> >> 1) >> Dumptime: Thu Feb 26 09:02:42 2009 >> Hostname: secrethostname >> Magic: FreeBSD Kernel Dump >> Version String: FreeBSD 7.0-RELEASE #0: Tue Nov 4 12:27:42 BRST 2008 >> root@:/usr/src/sys/i386/compile/SECRETHOSTNAME >> Panic String: ffs_blkfree: freeing free block >> 2) >> Dumptime: Fri Feb 27 11:30:59 2009 >> Hostname: secrethostname >> Magic: FreeBSD Kernel Dump >> Panic String: ffs_clusteralloc: map mismatch >> 3) >> Dumptime: Fri Feb 27 11:48:42 2009 >> Hostname: secrethostname >> Magic: FreeBSD Kernel Dump >> Panic String: ffs_blkfree: freeing free block >> 4) >> Dumptime: Tue Mar 3 10:30:28 2009 >> Hostname: secrethostname >> Magic: FreeBSD Kernel Dump >> Panic String: ffs_blkfree: freeing free block >> 5) >> Dumptime: Fri Mar 6 14:22:04 2009 >> Hostname: secrethostname >> Magic: FreeBSD Kernel Dump >> Panic String: ufs_dirbad: /disk1: bad dir ino 1131015 at offset >> 1536: mangled entry >> >> Tentei reproduzir o erro recriando a condição de arquivos grandes >> sendo movidos e/ou removidos dos sistemas de arquivos e não é sempre >> que acontece.
