Very basic, no md or LVM involved. /dev/sda2 is the backing device and /dev/sdb is the cache device. On top of bcache0 I'm running xfs: # parted -s /dev/sda p Model: ATA Hitachi HDP72505 (scsi) Disk /dev/sda: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 10.5GB 10.5GB primary xfs boot 2 10.5GB 499GB 489GB primary 3 499GB 500GB 1049MB primary linux-swap(v1) # parted -s /dev/sdb p Error: /dev/sdb: unrecognised disk label # grep bcache /proc/mounts /dev/bcache0 /srv xfs rw,relatime,attr2,inode64,noquota 0 0 # bcache-super-show /dev/sda2 sb.magic ok sb.first_sector 8 [match] sb.csum 7B66B1004B52FD9A [match] sb.version 1 [backing device] dev.uuid 3a131733-7d54-4feb-bf8c-62d6fbdbf935 dev.sectors_per_block 1 dev.sectors_per_bucket 1024 dev.data.first_sector 16 dev.data.cache_mode 1 [writeback] dev.data.cache_state 1 [clean] cset.uuid 2a108307-bab9-42dd-b072-10eeb0c13dd8 # bcache-super-show /dev/sdb sb.magic ok sb.first_sector 8 [match] sb.csum 88965AD15D35A500 [match] sb.version 3 [cache device] dev.uuid ffb6fc80-1dca-42d4-a951-cddee6af689e dev.sectors_per_block 1 dev.sectors_per_bucket 1024 dev.cache.first_sector 1024 dev.cache.cache_sectors 62498816 dev.cache.total_sectors 62499840 dev.cache.discard no dev.cache.pos 0 cset.uuid 2a108307-bab9-42dd-b072-10eeb0c13dd8 Does this help? cheers Carsten
