Current fstab record, including the underlying volumes: ========================================================================= LABEL=storage-1 /mnt/storage-1 btrfs defaults 0 0 LABEL=storage-2 /mnt/storage-2 btrfs defaults 0 0 LABEL=storage-3 /mnt/storage-3 btrfs defaults 0 0 LABEL=storage-4 /mnt/storage-4 btrfs defaults 0 0 none /mnt/bulk_storage aufs sum,udba=reval,create=mfsrr:4294967296,br=/mnt/storage-2=rw:/mnt/storage -3=rw:/mnt/storage-4=rw 0 0 ========================================================================= I simply use mount/umount to do and confirm this. The aufs volume is basically used to pool disks in a RAID0 fashion without the risk, which is mainly holding up, thanks :)
