I too experienced the issue of crashes when attempting to access md raid devices XCP 1.0-beta as discussed here:


Which seems also to be the same issue affecting XenServer 5.6.1 fp1:


So while the behavior seems to be slightly different, I'm still getting hard locks when attempting to access md raid devices. 

In XenServer 5.6.0, I have vm's running on md raid1 local storage:

# cat /etc/mdadm.conf
ARRAY /dev/md2 level=raid1 num-devices=2 metadata=0.90 UUID=763e7d0c:c7bcbdcd:65b5b8a6:3e6f4aba

# pvs
  PV         VG                                                 Fmt  Attr PSize   PFree 
  /dev/md2   VG_XenStorage-6ff20299-6078-d8b0-cd1b-3c725686652a lvm2 a-   923.50G 800.51G

# cat /proc/mdstat
Personalities : [raid1]
md2 : active raid1 sda3[0] sdb3[1]
      968371328 blocks [2/2] [UU]
Is this supposed to work in XCP 1.0?
