Hello Cephers, I am benchmarking CephFS. In one of my experiments, I change the object size. I start from 64kb. Everytime I do different block size reads and writes. By increasing the object size to 64MB and increasing the block size to 64MB, CephFS crashes (shown in the chart below). What I mean by crash is when I do "ceph -s" or "ceph -w" it gets into constantly reporting me reads, but it never finishes the operation (even after a few days!). I have repeated this experiment for different underlying file systems (xfs and btrfs), and the same thing happens in both cases. What could be the reason for crashing CephFS? Is there a limit for object size in CephFS?
Thank you, Hadi
