[dm-devel] Upgrade issues with v4.8

[Paul Cote]

I just recently upgraded to RHEL V4.5 and to Multipath tools V4.8 but
the paths are not being generated. I thought it may be a new
restrictions that would be managed via the multipath.conf file; but all
tweaks that I've made thus far have not made a difference. Falling back
to V4.7 works just fine but I would prefer to stay current with V4.8.

Any thoughts?

Dmesg does show some errors:

SELinux: initialized (dev 0:10, type nfs), uses genfs_contexts
device-mapper: dm-multipath: error getting device
device-mapper: error adding target to table
device-mapper: dm-multipath: error getting device
device-mapper: error adding target to table
device-mapper: dm-multipath: error getting device
device-mapper: error adding target to table
device-mapper: dm-multipath: error getting device
device-mapper: error adding target to table


With v4.7 ... The path list USE TO look like this;
