Hi, I have a question about using Swift when a node is full.

Currently I installed a swift server using SAIO. I split 4 nodes on the local stoage, let's call it Hard_drive_1. Now Hard_drive_1 is almost full so I add Hard_drive_2 to it and create one node on that. I add it to the ring and rebalance it, it works fine. I have tested by uploading some files and see the used space of Hard disk 2 is increasing, which means there are really files being written to it.

But my question is, it looks like the uploading also keep writing to Hard Disk 1, which is almost full.

So I want to know, what will happen if it Hard disk 1 is really full? will swift automatically notice that and then only write data to Hard Disk2?

Because if it still keeps writing to a full disk, it will cause the writing failure for sure.

thanks
