This is using CentOS 7. A previously used striped RAID stalls the boot,
because it is not found in /dev/mapper location.
When I tried a forced creation of a device using dmsetup using this
command:
# 'echo "0 $NumSectors striped 2 256 /dev/sdb 0 /dev/sdc 0" | dmsetup
create ddf1_4TB'
I get the following:
"Failure to communicate with kernel device-mapper driver.
Incompatible libdevmapper 1.02.135-RHEL7 (2016-09-28) and kernel driver
(unknown version).
Command failed"
Hence, I suspect something amiss with the new kernel 514.2 and/or
device-mapper.
If I regress via grub bootloader to 3.10.0-327.36.3.el7.x86_64, the
RAID0 works fine.
Any workaround assistance would be appreciated.
Thank you,
Adam Courville
