Dumping a live fs still will mean you end up restoring a not 100% consistent state of one file versus another and of file data for a given file. You have to weigh that against downtime. In most cases the downtime isnt worth it for having a few files that are logged in a transient state. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
