Hi all, We got some decommissioned servers from other projects for setting up OSDs. They've 10 2TB SAS disks with 4 2TB SSD. We try to test with bluestores and hope to play wal and db devices on SSD. Need advice on some newbie questions:
1. As there are more SAS than SSD, is it possible/recommended to put wal and db of multiple OSDs in partitions on same SSD (instead of using whole SSD device) ? 2. if ok to do 1., how to size the SSD partition for wal/db ? 3. do we need to tune parameters like bluestore_cache_size_ssd when SSD is used in OSD? Thanks a lot. Best Regards, /ST Wong
