Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

During last week we have made more tests. Firstly, we repeated the
test and again there where mismatches. What is more interesting
corrupted files were on source volume.
Then we repeated test again but files were copied localy(not via
iscsi) and drbd was disconnected. Files were ok.

Any ideas?
