Erro no sistema ao fazer backup em fita DDS
Boa tarde pessoal,
Hoje me deparei com um problema, qdo fui efetuar backup aconteceram duas
coisas, primeiro ocorrreu um erro no backup e depois a comunicacao com a
rede parou, uso Debian Sarge com Kernel 2.6 em Pentium 4 3.0 com 1 gb ram e
placa Asus P4P800-E Deluxe. Pude verificar tambem um processo chamado
pdflush consumindo 99,5% de CPU. Para fazer o backup uso o seguinte
comando.
#!/bin/bash
2
3 tar -cv -T /disk2/backup/backup_dirs -f /dev/st0
4
5 eject -q /dev/st0
Os erros são estes abaixo, se alguem puder me ajudar agradeço.
