    Hi Gabor,

    It's a strange condition. SnapRAID found two different files that have the same inode information. Theoreticalyl something that should not happen.

    What filesystem are you using ? NTFS ? Or maybe ReFS or something other ?

    My expectation is that you'll get the same error even with older SnapRAID versions. Did you tried one ?

    Anyway, what is this .BPF file ? Is it maybe associated to an application that is running ?

    Ciao,
    Andrea

    Hi Andrea!

    Your question (What filesystem are you using?) was very good.

    Originaly:
    Z:, Y:, X: (big, parity) NTFS
    T:, S:, R:, Q: (small, content) FAT32
    W:, V:, U: (small, data) FAT32

    1. step: copy 37 file (3.3 GB) -> W:
    2. step: sync OK
    3. step: copy 354 file (3.3 GB) -> V:
    4. step: diff OK
    5. step: sync OK
    6. step: copy 36542 file (7.2 GB) -> U:
    7. step: diff failed
    8. step: sync failed

    Then I modified contents of U: drive several steps without success:

    After delete U:/data3/DEVEL/#2011-06-28/#32/P13/BCB2GCC/Project2.bpf:
    ...
    add U:/data3/DEVEL/#2011-06-28/#32/P13/save_inf.cpp
    Internal inode '8497741984' inconsistency for files 'U:/data3/DEVEL/#2011-06-28/#32/

    atching and already present but different

    with snapraid 8.0 same:
    ...
    add U:/data3/DEVEL/#2011-06-28/#32/P13/save_info.h
    Internal inode '8497742080' inconsistency for files 'U:/data3/DEVEL/#2011-06-28/#32/
    P13/shm_i.cpp' and 'U:/data3/DEVEL/#2011-06-28/#32/P13/BCB2GCC/QM_SRV.CPP' m
    atching and already present but different

    After delete full U:/data3/DEVEL/#2011-06-28 directory:
    ...
    add U:/data3/DEVEL/#_debug/2015_10_15-szikla-forras/src/gykeres.dfm
    Internal inode '1030619200' inconsistency for files 'U:/data3/DEVEL/#_debug/2015
    _10_15-szikla-forras/src/gykeres.h' and 'U:/data3/DEVEL/#_debug/2015_10_15-szikl
    a-forras/src/BIN/a2as.exe' matching and already present but different

    Finally format U: to NTFS (W: and V: remain FAT32),
    copy 36542 file (7.2 GB) -> U:

    Then

    snapraid diff
    ...
    391 equal
    0 moved
    0 copied
    0 restored
    0 updated
    0 removed
    36542 added
    There are differences!

    Hi Gábor,

    Thanks for the report.

    I've now added in the FAQ the recomendation to convert FAT to NTFS in case this error appears.

    Ciao,
    Andrea

    The problem does not occur with exFAT FS.
