So, doing nothing and wait for the ceph to recover? In theory there should be enough disk space (more disks arriving tomorrow), but I fear that there might be an issue, when the backups get exported over night to this s3. Currently the max_avail lingers around 13TB and I hope, that the data will go to other PGs than the ones that are currently on filled OSDs. Am Di., 23.
