parece que meu sistema de arquivos cresce para 100% enquanto faz o rsync e é provavelmente por isso que ele falha!
Eu verei para estendê-lo e reexecutar o processo novamente (eu também tive um erro de chave ssh)
Eu tenho algum tipo de script de sincronização transferindo arquivos de um servidor de produção para um DR todos os dias via rsync.
no entanto, desde alguns dias, o script parece estar falhando.
eram várias instâncias dele em execução, então eu as matei todas e reiniciei o processo, no entanto, parece que não faz nada.
ao traçar o PID com strace, eu posso ver relendo os mesmos dados de novo e de novo.
os comandos executados pelo wrapper são:

apenas inundando esse mesmo bloco várias vezes (o FS é de cerca de 150Gbytes)
como posso investigar por que está fazendo isso? (estava funcionando perfeitamente antes) Eu não posso reiniciar a máquina como está em prod.
poderia estar relacionado a um link ruim ou a qualquer coisa na pasta? ou um arquivo em uso? (aparentemente nenhum está em uso, olhando para os processos em execução), há opções RSYNC adicionais que eu poderia adicionar para corrigir isso?
obrigado por suas dicas respeita,
Eu tentaria primeiro verificar se o rsync está funcionando corretamente. Crie um pequeno diretório de teste com alguns arquivos na origem e sincronize apenas com o destino para ver se funciona. Adicione também a opção --stats --verbose .
Acredito que isso possa estar relacionado à rede. Você pode verificar e ver se há algum problema de rede?
