Meu sistema de arquivos btrfs está de alguma forma danificado (transid pai, erros internos, ...). Eu tentei com opções de reparo, mas acho que alguns dos sistemas de arquivos estão confusos agora. O volume btrfs é usado para backups. Portanto, perder alguns backups não é grande coisa. Mas eu só quero que o sistema de arquivos retorne a um estado saudável.
Como?
