mdraid doesn't allow creation: device or resource busy
Dear fellow CentOS users,
I have never experienced this problem with hard disk management before
and
cannot explain it to myself on any rational basis.
The setup:
I have a workstation for testing, running latest CentOS 7.3 AMD64. I am
evaluating oVirt and a storage-ha as part of my bachelors thesis.
I have already been running a RAID1 (mdraid, lvm2) for the system and
some oVirt 4.1 testing.

multipath
Hi.
Somehow I do not see any out put using multipath -l or multipath -ll . But I
can see using dry run ie multipath -d.
Also I do not see /dev/dm-*
It was there before. How do I re claim it.
Thanks!
Paras.

IBM Storwize V3700 storage - device names
Hello,
I have IBM Storwize V3700 storage, connected to 2 IBM x3550 M4 servers
via fiber channel. The servers are with QLogic ISP2532-based 8Gb Fibre

PCI Express HBA cards and run Centos 5.10
When I export a volume to the servers, each of them sees the volume
twice, i.e /dev/sdb and /dev/sdc, with the same size.
Previously I have installed many systems with IBM DS3500 series of
