Hi, i have some IO issues, and after Christian's great article/hint about caches i plan to add caches too. So now comes the troublesome question: How much dangerous is it to add cache tiers in an existing cluster with around 30 OSD's and 40 TB of Data on 3-6 ( currently reducing ) nodes. I mean will just everything explode and i just die, or how is the road map to introduce this, after you have an already running cluster ? Anything that needs to be considered ? Dangerous no-no's ? Also it will happen, that i have to add the cache tiers server by server, and not all at the same time. I am happy for any kind of advice. Thank you ! -- Mit freundlichen Gruessen / Best regards Oliver Dzombic IP-Interactive mailto:info@xxxxxxxxxxxxxxxxx Anschrift: IP Interactive UG ( haftungsbeschraenkt ) Zum Sonnenberg 1-3 63571 Gelnhausen HRB 93402 beim Amtsgericht Hanau Geschäftsführung: Oliver Dzombic Steuer Nr.: 35 236 3622 1 UST ID: DE274086107 _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
