This should probably be against util-linux, not dasher. Reassigning. Can you show the results of "dmsetup table" ?

[root@perf6 dev]# dmsetup ls mpath2 (253, 0) mpath1 (253, 7) VolGroup01-LogVol01 (253, 12) VolGroup01-LogVol00 (253, 11) mpath1p3 (253, 10) VolGroup00-LogVol01 (253, 6) mpath5 (253, 4) mpath1p2 (253, 9) VolGroup00-LogVol00 (253, 5) mpath4 (253, 3) mpath1p1 (253, 8) mpath3 (253, 2) mpath2p1 (253, 1) Ok, I don't think anything is going wrong here -- you can't mount /dev/mpath2 directly because it has a partition on it, which is mpath2p1. Do "parted /dev/mpath2 p" to see the partition table for more info on that. |
