Hello, As far as I can tell there is no way to shrink a db/wal after creation. I recently added a new server to my cluster with SSD's for the wal/db and just used the ceph dashboard for deployment. I did not specify a db size, which is my mistake, it seems by default it uses "block.db has no size configuration, will fallback to using as much as possible". So now my issue is I added 2 more drives, but with no space left on the SSD's get "2 fast devices were passed, but none are available". I had 7 4TB HDD and 2 2Tb SSD's and added 2 more 4TB. Distribution is 4 and 3 between the 2 SSD's. I just want to confirm, the best option is to set the bluestore_block_db_size/wal_size, zap and let them be recreated with a size of 300 and 2. I chose those just because I have space. I'm not going to do them all at the same time.
