Your weights should more closely represent the size of the OSDs. OSD3 and OSD6 are weighted properly, but your other 3 OSDs have the same weight even though OSD0 is twice the size of OSD2 and OSD4.
Your OSD weights is what I thought you were referring to when you said you set the crush map to 1. At some point it does look like you set all of your OSD weights to 1, which would apply to OSD1. If the OSD was too small for that much data, it would have filled up and be too full to start. Can you mount that disk and see how much free space is on it? Just so you understand what that weight is, it is how much data the cluster is going to put on it. The default is for the weight to be the size of the OSD in TiB (1024 based instead of TB which is 1000). If you set the weight of a 1TB disk and a 4TB disk both to 1, then the cluster will try and give them the same amount of data. If you set the 4TB disk to a weight of 4, then the cluster will try to give it 4x more data than the 1TB drive (usually what you want). In your case, your 926G OSD0 has a weight of 1 and your 460G OSD2 has a weight of 1 so the cluster thinks they should each receive the same amount of data (which it did, they each have ~275GB of data). OSD3 has a weight of 1.36380 (its size in TiB) and OSD6 has a weight of 0.90919 and they have basically the same %used space (17%) as opposed to the same amount of data because the weight is based on their size. As long as you had enough replicas of your data in the cluster for it to recover from you removing OSD1 such that your cluster is health_ok without any missing objects, then there is nothing that you need off of OSD1 and ceph recovered from the lost disk successfully.
