[ceph-users] ceph crushmap question
Hi. I'm newbie with ceph. I know that i can define custom types in crush map. And type id 0 used always for devices. But if i specify type 0 slot Does i need to specify devices with this name or use predefined name device? For example: type 0 device device 0 osd.0 class hdd or type o slot slot 0 slot1-1 class hdd My use case - i have udev rules on my servers that maps device with serial number to specific server slot. So when disk dies i know which slot needs to be replaced. (In my server led uid to identify disk does not work). And i want to use my disk names (slot1, slot2 and so) inside ceph crush map. -- Vasiliy Tolstov, e-mail: v.tols...@selfip.ru ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
