I've typically gotten past situations like this by increasing the pg's to spread the load better where it's complaining. If you're at 16, jump to 64 or 128. Aug 16, 2025 02:40:48 Florent Carli <fcarli@gmail.com>:
Hello,
I’m running Ceph 19.2.3 with cephadm on a 3-node cluster, and I recently started seeing the following warning related to free fragmentation:
HEALTH_WARN 3 OSD(s) [WRN] BLUESTORE_FREE_FRAGMENTATION: 3 OSD(s) osd.0 0.802713 osd.1 0.803276 osd.2 0.803870
I haven’t been able to find clear guidance on how to address this issue. Are there any recommended approaches or best practices for reducing BlueStore free space fragmentation?
Thanks in advance for your help!
