ceph-volumeattacher: failed rbd single_major check, assuming it's unsupported: failed to check for rbd module single_major param: Failed to complete 'check kmod param': exit status 1. modinfo: ERROR:
could not get modinfo from 'rbd': Exec format error
modinfo rbd
filename: /lib/modules/3.10.0-693.21.1.el7.x86_64/kernel/drivers/block/rbd.ko.xz
solve:
Install the xz decompression command in the container, because the library file in the new version of the kernel is the xz compressed package
Or decompress the rbd.ko.xz of the host, and softly connect the decompressed rbd.ko to rbd.ko.xz, so that the container does not need to be decompressed
