Hi, maybe someone can enlighten me. I am doing btrfs send & receive with full snapshots and incremental updates.
It basically looks like this: vol-0 and vol-1 are full subvolume image sends. inc-1 and inc-2 are incremental images with: # btrfs send -f inc-1 -p vol vol' # btrfs send -f inc-2 -p vol' vol'' Case A: vol---send----> vol-0 --receive--> avol --send&rec--> bvol |-----send----> inc-1 --receive--> | | <--receive-- inc-1 vol' -send----> vol-1 avol' bvol' |-----send----> inc-2 --receive--> | | <--receive-- inc-2 vol'' avol'' bvol'' which, works for bvol and which even works, if bvol is removed before inc-2 is applied to bvol'. Case B: vol---send----> vol-0 --receive--> avol |-----send----> inc-1 --receive--> | vol' -send----> vol-1 avol' --send&rec--> bvol' |-----send----> inc-2 --receive--> | | <--receive-- inc-2 vol'' avol'' ERROR trying to apply inc-2 to bvol' fails with: ERROR: could not find parent subvolume What's the problem here? -- 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
