Hi,

I have a data block like 0000008EA20A1102030000000120000100120C07003000004E05000F02000F13022300311200D00A00041000390E00E01000403A001001110080FF0001000F070A810C000F02000113301500133E0800F010A9DD71709100000079E205AEDD3E000086F7AEDFEA8A10006383FC5F6AA05DBC000F0200FFEB0155020F0200FFFFFFFFFFFFFFFFFFFFFFFFFF30500000000000000000000000000000000000000000000000000000000000000000000000 which is compressed with lz4 algorithm.Is there any source code or library or API by which i can decompressed this block.

I am working on deleted zpool and want to recover deleted zpool data. For this i need metadata information but all metadata is compressed by default. I am not able to read blockpointer information MOS information etc.how can i decompress metadata to read information on windows.

thanks
