Redimensionei uma partição (ext4) de um Live CD com GParted e, após a reinicialização, diz que o sistema de arquivos é somente leitura.
Reiniciei novamente a partir do CD e verifiquei com o GParted sem erros.
Como eu pude descobrir por que ele remonta o sistema de arquivos no modo somente leitura?
edit: Inicia normalmente, mas depois de algum tempo, o ponto de montagem "/" é remontado com configurações somente leitura, então acho que eventualmente haverá erros.
Existe alguma outra maneira de repará-lo?

Devo tentar remover o arquivo com o ID do inode. 5636499?
Este é o caminho do arquivo:
~/.cache/google-chrome/Default/Cache/data_3
(É possível verificar se existem outros arquivos como este?)
editar: depois de excluir o cache do Chrome, esse erro não ocorreu.

Respostas:
Há algo errado com os metadados para o arquivo de cache do cromo. Pode não ser prejudicial excluir os arquivos de cache, mas o fsck com o sinalizador -f (force) deve corrigir esse problema de qualquer maneira. (esclarecimento por IR: execute fsck no livecd, pois ele precisa ser executado em uma partição desmontada)
Se você precisar remontar o disco no modo de leitura / gravação, tente o seguinte:
Editar: isso parece fazer parte de um problema maior e não resolvido do Ext4. Outras pessoas tiveram o mesmo problema após redimensionar ou copiar partições (e algumas vezes sem fazer isso).
