I recently had the misfortune of finding out that version lvm-user-1.0.5 included a version of lvmcreate_initrd that miscalculated the initrd-lvm-$KERNELVERSION.gz. This would come up with errors at boot, but not during the creation of the initrd image. There is a thread on this: http://forums.gentoo.org/viewtopic.php?t=14014 I fixed the issue I had with it and posted it. I uncommented the "INITRDSIZE=" line, and added a value of 4096. (a little over my initrd-lvm-2.4.19.gz loopback size) It appears that the auto-calculation does not leave enough room in the initrd to actually write the /etc/lvmtab & /etc/lvmtab.d files when it is acting as a temporary root. I am not sure how to fix this permanently, but I wanted to bring it to the attention of the maintainers of Gentoo.
seemant, i think some kernel dude would better understand this
I just re-upgraded to 1.0.5 and re-made my initrd-lvm-2.4.19.gz with lvmcreate_initrd (this time without any changes to the INITRDSIZE= variable) and it made it alright. I lessened the number of modules I am using, so I think it has something to do with sizing of the modules, perhaps? Might not be something Gentoo specific, the more I'm looking at it. Probably LVM Project specific.
sorry to dump this one back to the field again, but I know less than nothing about LVM...
Perhaps we should just close this bug.. I haven't ran into the issue again. Perhaps it was an anomoly? However, another person had the same anomoly. I'm not sure what we can do since it is a LVM issue, the more I think about it.
