  Your root filesystem on `/dev/sdb1` shows as 100% in use which is where your `/opt/bitnami/php/var/run/session` is probably located and makes sense of the error message you are getting.
  
  You either need to expand that `/dev/sdb1` filesystem or move some files from that to another filesystem. You have 15G free on `/mnt` so you could look at relocating `/opt` or `/opt/bitnami` to `/mnt` - but it depends how big those subtrees are and what level of access you have.
  
  It's just a disk space issue and nothing to do with CiviCRM.
