Release 2016_010 (2016-03-17)¶
To update Qeumu, all virtual machines will be restarted. Individual maintenance windows will be scheduled and announced.
Reduce OSD journal size and make more frequent flushes. This should further reduce IO spikes on the magnetic disks.
For all machines, mark maintenance start and end in the configuration database. This helps to automatically silence monitoring during that time which in turn gives a better view over real problems. (#20238)
