hello All,
I know the issue is related to libvirt,but i dont know
where to ask.
i have centos 6.6 running KVM as compute node in openstack icehouse
when i try to attach volume to instance it shows
2596: error : virStorageFileGetMetadataRecurse:952 : Failed to open
file '/dev/mapper/Mar': No such file or directory
in libvirt log
This does not always happen when it happens no one will be able to
attach volume to instance
using EMC VNX as storage backend.
multipath.conf
# Skip the files uner /dev that are definitely not FC/iSCSI devices
# Different system may need different customization
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
devnode "^hd[a-z][0-9]*"
devnode "^cciss!c[0-9]d[0-9]*[p[0-9]*]"
# Skip LUNZ device from VNX
