As far as I can tell ES distributes segments over all data paths and if you have reliable disks i.e. raid 0 etc. then this is a good policy but if you are using single disks then failure of a single disk can affect all shards on a node. I am pretty sure that ES can recover from such a failure but in my case it means that I am going to go from a few TB that needs to be copied to tens of TB.
Does anyone have any practical experience of disk failure and recovery? Are there any settings to force all segments in a shard to be created in the same data path? I guess that I will need to restrict the number of disks per node and have more nodes instead. /Michael -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
