Hi, Since yesterday on ceph octopus it started to crash multiple osds in the cluster and I can see this error in most of the logs: 2024-09-12T06:13:35.805+0700 7f98b8b27700 1 bluefs _allocate failed to allocate 0xf0732 on bdev 1, free 0x40000; fallback to bdev 2 2024-09-12T06:13:35.805+0700 7f98b8b27700 1 bluefs _allocate unable to allocate 0xf0732 on bdev 2, free 0xffffffffffffffff; fallback to slow device expander The osds are 57% full so I think space issue shouldn't happen. I'm using ssds so I don't have separated wal/rocksdb. Running some compaction now but I don't think it will happen on a long run. What could be this issue and how to fix?
