Hmm, that's probably a bug in the journal replay code. :( Can you send me the output of "e2image -r /dev/sdXX - | bzip2 > hd.e2i.bz2" if it's not too huge? The exact error messages (if you can capture/photograph them) would also be useful. I'm guessing you have metadata_csum enabled... PS: lkml.org is dead; I'm assuming the URL referenced the discussion "Ext4 Recovery: Invalid checksum recovering block # in log" but it's hard to tell since there was no subject line provided with that URL. --D > > > Thanks, > Markus > > > PS: Original lkml-mail: > https://lkml.org/lkml/2014/4/1/467 > -- > To unsubscribe from this list: send the line "unsubscribe linux-ext4" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
