Hi Giuseppe, Would you like to tell some details about: 1. the XYZ snapshot was taken from which subvolume 2. where the base (initial) snapshot is stored 3. The 3 partitions receives the same snapshot, are they in the same btrfs configuration and subvol structure?
Also, would you send the link reports "two files unreadable error" post mentioned in step 2? Hope can see the message and figure out if the issue first comes from sender or receiver side.

The point at which the problem it appeared, is similar in all three cases. Subvolume structure and operations sequence: btrfsreceive/ btrfsreceive/root/ btrfsreceive/root/.part/ 1) Sending XYZ differential snapshot in to ' btrfsreceive/root/.part/ '. 2) Create snapshot from ' btrfsreceive/root/.part/XYZ ' to ' btrfsreceive/root /XYZ '. 3) Delete snapshot ' btrfsreceive/root/.part/XYZ '. Always in step 2) I had two files unreadable error (view previous posts), and one already existing object error (see below). All three times I had to re-create from scratch the various partitions (on disks and systems different). I can help you, in some way, to find the problem? Or is useless to continue report it? dic 18 18:29:58 exnetold.gdb.it kernel: ------------[ cut here ]------------ dic 18 18:29:58 exnetold.gdb.it kernel: WARNING: CPU: 1 PID: 4325 at fs/btrfs/extent-tree.c:2960 btrfs_run_delayed_refs+0x283/0x2b0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS: Transaction aborted (error -17) dic 18 18:29:58 exnetold.gdb.it kernel: Modules linked in: fuse xt_CHECKSUM ipt_MASQUERADE nf_nat_masquerade_ipv4 tun nf_conntrack_netbios_ns nf_conntrack_br dic 18 18:29:58 exnetold.gdb.it kernel: soundcore acpi_cpufreq tpm_tis tpm_tis_core tpm nfsd auth_rpcgss nfs_acl lockd grace sunrpc ata_generic nouveau vide dic 18 18:29:58 exnetold.gdb.it kernel: CPU: 1 PID: 4325 Comm: umount Tainted: G W 4.8.8-100.fc23.x86_64 #1 dic 18 18:29:58 exnetold.gdb.it kernel: Hardware name: System manufacturer System Product Name/M2N, BIOS 0902 02/16/2009 dic 18 18:29:58 exnetold.gdb.it kernel: 0000000000000286 00000000dd260fac ffff8ffa0d25bb60 ffffffffbc3e493e dic 18 18:29:58 exnetold.gdb.it kernel: ffff8ffa0d25bbb0 0000000000000000 ffff8ffa0d25bba0 ffffffffbc0a0ecb dic 18 18:29:58 exnetold.gdb.it kernel: 00000b9000000049 ffff8ff9e61b40a0 ffff8ffa2da77800 ffffffffffffffff dic 18 18:29:58 exnetold.gdb.it kernel: Call Trace: dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc3e493e>] dump_stack+0x63/0x85 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc0a0ecb>] __warn+0xcb/0xf0 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc0a0f4f>] warn_slowpath_fmt+0x5f/0x80 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07eb4e3>] btrfs_run_delayed_refs+0x283/0x2b0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07d62ec>] ? btrfs_cow_block+0x10c/0x1e0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07ff62e>] commit_cowonly_roots+0xae/0x2e0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07eb466>] ? btrfs_run_delayed_refs+0x206/0x2b0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc08706b4>] ? btrfs_qgroup_account_extents+0x84/0x180 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc0802187>] btrfs_commit_transaction+0x547/0xa40 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07faa9f>] btrfs_commit_super+0x8f/0xa0 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07fcbcb>] close_ctree+0x2db/0x380 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc26d3da>] ? evict_inodes+0x15a/0x180 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07ccf29>] btrfs_put_super+0x19/0x20 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc2520bf>] generic_shutdown_super+0x6f/0xf0 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc2523b2>] kill_anon_super+0x12/0x20 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffc07cdd98>] btrfs_kill_super+0x18/0x110 [btrfs] dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc252763>] deactivate_locked_super+0x43/0x70 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc2527ec>] deactivate_super+0x5c/0x60 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc2711bf>] cleanup_mnt+0x3f/0x90 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc271252>] __cleanup_mnt+0x12/0x20 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc0bf0ce>] task_work_run+0x7e/0xa0 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc0032d2>] exit_to_usermode_loop+0xc2/0xd0 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc003bf1>] syscall_return_slowpath+0xa1/0xb0 dic 18 18:29:58 exnetold.gdb.it kernel: [<ffffffffbc7ffb3a>] entry_SYSCALL_64_fastpath+0xa2/0xa4 dic 18 18:29:58 exnetold.gdb.it kernel: ---[ end trace f7eb2e818f727168 ]--- dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS: error (device sda3) in btrfs_run_delayed_refs:2960: errno=-17 Object already exists dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS info (device sda3): forced readonly dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS warning (device sda3): Skipping commit of aborted transaction. dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS: error (device sda3) in cleanup_transaction:1854: errno=-17 Object already exists dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS error (device sda3): commit super ret -17 dic 18 18:29:58 exnetold.gdb.it kernel: BTRFS error (device sda3): cleaner transaction attach returned -30 -- 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 -- 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
