Hi, the main ceph-disk interface added is part of the prepare. We add fcache, fcache_size, fcache-uuid optional arguments. These are the only external interface. When you want to use flashcache, you must specify flashcache disk and flashcache size such as ceph-disk prepare --fcache /dev/sdc --fcache_size 10 /dev/sda. I think we could add bcache and dm-cache in the same way if needed. What do you think? 发件人: Sage Weil [mailto:notifications@xxxxxxxxxx] 发送时间: 2016年5月7日 3:58 收件人: ceph/ceph 抄送: houlinfei 11802 (RD); Author 主题: Re: [ceph/ceph] Wip add flashcache (#8773) I think we want to make this more generic so that we can layer in any caching option (flashcache, bcache, dm-cache). Can you send an email to ceph-devel with the proposed ceph-disk interface change so we can get feedback and settle one the approach? Thanks! — You are receiving this because you authored the thread.
