I apologize if this is the wrong place to be seeking assistance. The OS specific support lists didn't seem to know anything about this issue. I updated my system and after reboot the logical volumes did not mount. A quick search and I found that /dev/vg0/lvol0 was missing from the /dev tree. However, they logical volume seems to be intact from the output of LVM. I found what appears to be an issue that device-mapper is running into on boot: Current Software: Linux 2.6.18-238.12.1.el5 #1 SMP Tue May 31 13:23:01 EDT 2011 i686 i686 i386 GNU/Linux device-mapper-1.02.55-2.el5 Kernel Messages: device-mapper: multipath: version 1.0.6 loaded device-mapper: table: 253:4: linear: dm-linear: Device lookup failed device-mapper: ioctl: error adding target to table I did some research and the only info I could find was regarding dmsetup: #dmsetup status pdc_eehgddjjp1: 0 976768002 linear pdc_eehgddjj: 0 976772992 linear via_cdeadaheebp1: 0 976768002 linear via_cdeadaheeb: 0 1953546240 striped 2 8:0 8:16 1 AA Looks like something is wrong with the vg0-lvol0 entry above, but I can't figure out how to fix it. There is also another HDD on each of the via and pdc controllers that are seen by the system, but not showing up in the "status" list above. There is also a disk connected to PATA port "/dev/hda" that is part of the lvol. The device-mapper device is being created for the lvol: /dev/mapper/vg0-lvol0 David -- David Cramblett -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
