Mixing ssd and hdd in production is fine. Not sure if size=2 is "fine" though. Also, having as many drives/hosts as the size parameter is also not really a good combination with "production". Any surprise, any maintenance on one ssd will make the ssd pools stop, and the cluster can not recover until that one ssd is back again, since there is no other ssd to recover onto. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- [email protected] To unsubscribe send an email to [email protected]
