Hi!
-----Original Message----- From: linux-bcache-owner@vger.kernel.org [mailto:linux-bcache- owner@vger.kernel.org] On Behalf Of Vasiliy Tolstov Sent: jeudi 23 janvier 2014 20:26 To: linux-bcache@vger.kernel.org Subject: bcache using in case of 5 hdd disks Hi all. I'm very happy with bcache on current production system (raid1 with 1 sata hdd + 1 ssd). But now i get new platform with 5 sata hdd and 1 ssd disk. Each of sata hdd i need to format with some fs (ext4 or btrfs?) to store data. How can i use bcache in this case? I'm unerstand that i can create5 partitions on ssd drive and use each partition to each drive. But does it possible to use whole ssd disk to cache in this case?
My understanding is that a single "cacheset" (in your case, your SSD) can be shared between multiple backing devices. You should be able to attach a single cacheset's UUID to multiple devices. Can anyone else confirm ?
