One that I remember is the "want_replacement" mechanism, which was initially only available via "echo > /sys/..." but quickly got added to mdadm as "--replace". People (and various outdated wikis) also tend to suggest using "echo check..." or "echo repair...", but those are available in mdadm as well, via "--action=". Lastly, I change the "stripe_cache_size" via /sys/, but that's fine-tuning, which feels OK to do via sysfs parameters, whereas needing to use sysfs for the most basic operations of managing the storage system does not. -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
