Uhm, the other day I change my #Ceph setup that way, that I now use #FRR & #OSPF to utilize both links in my 3-node setup. So each node has a dedicated 10 GbE link to its neighbours, forming a ring (or triangle).
Then I also changed my setup and added a SSD as my WAL/DB device for my OSDs (2 TB SSD split into 2x 1 TB for WAL/DB, one for each OSD).
Although I see a slight speed increase in recovery speed, the increase is still below the expected performance: only 100-150 MB/s in most cases with 2x Seagate Exos X18 18 TB drives. Each drive can deliver up to 270 MB/s, according to technical datasheet.
So, I would expect to see more like 200-400 MB/s.
MTU is 9000 bytes .
ceph -s reports:
recovery: 182 MiB/s, 8 keys/s, 144 objects/s
Any ideas how to increase the speed?
