Hi All,
Has anyone faced a similar issue? I do not have a problem with random read, sequential read, and sequential writes though. Everytime I try running fio for random writes, one osd in the cluster crashes. Here is the what I see at the tail of the log:
ceph version 0.94.6 (e832001feaf8c176593e0325c8298e3f16dfb403)
