All those names seem suspicious. We will check whether there is a
rationale for this format or the names got messed up somehow. The _00
volume number is certainly suspicious too. Drbdmanage used to expand
single-digit volume numbers to 2 digits, whereas LINSTOR was supposed to
always use 5 digit volume numbers (this was done so that other software
could easily sort backend volume storage names created by LINSTOR).
