Hi, I recently e-mailed ceph-users about a problem with virtual machine RBD disks remounting read-only because of OSD slow requests[1]. I just wanted to report that although I'm still seeing OSDs from one particular machine going down sometimes (probably some hardware problem on that node), the virtual machines haven't been remounting their disks read-only.
I can't be sure of the cause, because I didn't do any controlled tests (or any tests at all), but one thing I changed was the osd_recovery_op_priority, from the default 10 to 5. I had seen some suggestions on this list regarding that parameter and they may well have been useful in my case.
