kernel 3.10.0-862.6.3 hanging when loading raid
Re: kernel 3.10.0-862.6.3 hanging when loading raid
no fake raid. boot/os drive is normal sata mdraid. storage volumes are lvm raid10 on multipath'd sas drives.
Re: kernel 3.10.0-862.6.3 hanging when loading raid
i set up a test box and created a volume group (vg) with 12 devices in it, then did this:
lvcreate -m 1 -i 6 --size=1G --name v0 vg
to create a raid10 that should use all 12 drives (6 stripes with 1 mirror)
and that crashed the system (blinking caps/num lock)
i'll try a few other variations to see what happens.

reduced vg to 2 drives, and then:
vgreate -m 1 -i 1 --size=100M --name=v0 vg
also causes crash.
vgreate -m 1 -i 1 --size=100M --name=v0 vg
also causes crash.
Re: kernel 3.10.0-862.6.3 hanging when loading raid
lvcreate -m 1 --size=10M --name=v0 vg
also crashes. these last tests were all just using loop devices.
seems like this should be enough info to work on.
should i submit an upstream bug, or does the centos group handle that nowadays? i'm not a paid upstream customer.

Please file a bug at bugzilla.redhat.com: Red Hat > Red Hat Enterprise Linux 7 > component kernel. You can mention that you are using CentOS.

i'm going to try and capture some kernel panic screenshots to upload to the bug. if anyone else has data to add, feel free (assuming the bug is public).

Kernel bugs are automatically marked private. As the reporter, you can add email addresses of other bugzilla account holders to the list and they can then see it.
The future appears to be RHEL or Debian. I think I'm going Debian.
