[ceph-users] krbd crc

Hi, I have a few questions about krbd on kernel 4.15 1. Does it support msgr v2? (If not which kernel supports msgr v2?) 2. If krbd is using msgr v1, does it checksum (CRC) the messages that it sends to see for example if the write is correct or not? and if it does checksums, If there were a problem in write how does it react to that? For example, does it raise I/O Error or retry or...? Thanks.
