Hi, I have couple of queries related to btrfs-image, btrfs send and with combination of two. 1) I would like to know if a btrfs source file system is spread across more than 1 disks, does btrfs-image require same number of disks to create empty file system without files content??
2) would btrfs-image can be modified to keep only given subvolume foot print and related meta data to bring back file system live on destination disk? To elaborate more on this, Lets say I have 5 subvolumes on source btrfs and i run btrfs-image written to destination disk say /dev/sdd. In this process, can btrfs-image modified to just have only 1 subvolume and skipp other 4 subvolumes and write to destination i.. /dev/sdd so that when I mount /dev/sdd , I will have btrfs with only 1 subvolume with no data. 3) If 3 can successful, can btrfs-image further changed to include data of selected subvolume which gives files data also written to /dev/sdd which would be kind of a backup of a subvolume taken out of a btrfs file system which is having more than 1 subvolumes. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
