Hi all,
After I upgrade from 14.2.9 to 14.2.14 my OSDs are using less more memory than before! I give each OSD 6GB memory target and before the free memory was 20GB and now after 24h from the upgrade I have 104GB free memory of 128GB memory! Also, my OSD latency got increases! This happens in both SSD and HDD tier.
Are there any notes from the upgrade I missed? Is it related to bluefs_buffered_io? If BlueFS do a direct IO shouldn't BlueFS/Bluestore use the targeted memory for its cache and does it mean before the upgrade the memory used was by a kernel that buffers the IO and wasn't for the ceph-osd?
Thanks.
