Could you make dumps of #346754, #347335, #6917 segments and send only on my personal e-mail for analysis? Example: dd if=3D of=3D bs=3D4096 skip=3D710152192 count=3D2048 (710152192 =3D=3D 346754 * 2048) With the best regards, Vyacheslav Dubeyko. > I have not found new bad btree nodes in recent days.
