Package: mdadm
Version: 3.3.4-1.1+b1
Severity: normal
hello,
mdadm eats all CPU time of all cores.
This ShouldNotHappen(tm)
I had a lvm volume on a disk which failed while I was trying to upgrade
the volume to raid1 so my raid configureation is very broken.
killing mdadm only helps temporarily. it restarts itself.
Is there any debug information I can provide before I trash the disks?
Thanks
Michal
