Hi, thanks for your valuable input. Question: Can I get more information of the 6 clients (those with features 0x40106b84a842a42), e.g. IP, that allows me to identify it easily? Regards Thomas Am 16.09.2019 um 15:56 schrieb Paul Emmerich:

Hello,
the current kernel with SLES 12SP3 is: ld3195:~ # uname -r 4.4.176-94.88-default
Assuming that this kernel is not supporting upmap, do you recommend to use balance mode crush-compat then? Hi Thomas,
Among the clients listed in your output, only 6 don't support upmap (those with features 0x40106b84a842a42). The rest do.
Regards Thomas
