Background: Norton utilities screwed up the partition table on one of my lvm drives. I tried a pvcreate -ff to recover but ended up losing the lvm partitions. I lost all of my partitions with the exception of /, /lib and /usr, so the system is still bootable and most of the system apps are still available. (I did lose /var, though the system has automagically recreated some of the directories). This is on a Debian/sid box running kernel 2.4.19 and devfs. The hardware allocated to pvs are /dev/hda3 (27GB), /dev/hdc (30GB) and /dev/hde (30GB). I tried to create the pvs and got the following: # pvcreate /dev/hda3 modprobe: Can't locate module /dev/lvm modprobe: Can't locate module /dev/lvm modprobe: Can't locate module /dev/lvm modprobe: Can't locate module /dev/lvm modprobe: Can't locate module /dev/group pvcreate -- physical volume "/dev/hda3" successfully created for subsequent creates (pvcreate /dev/hdc; pvcreate /dev/hde), I get a response of "modprobe: Can't locate module /dev/group"; both claim to be successfully created. I then try to create the volume group: # vgcreate vg00 /dev/ide/host0/bus0/target0/lun0/part3 /dev/ide/host0/bus1/target0/lun0/disc /dev/ide/host2/bus0/target0/lun0/disc modprobe: Can't locate module /dev/vg00 invalidate: Busy buffer vgcreate -- no valid physical volumes in command line The other night, I attempted to rebuild and restore the system. It came up in single user, and after three hours of recreating volumes, partitions and restoring from backups, I tried to go to multiuser. It rebooted and the LVs disappeared. LVM is compiled monilithically into the kernel rather than as modules. Since I have been running it for about a year, it is 1.0.1-rc4. I have the following questions: 1. Why is modprobe getting these devices (/dev/vg00, /dev/lvm, etc) which it then cannot find? 2. Why is, after I rebuild the volume, it not persisting between reboots? 3. What should I do to get these back permanently? 4. Would upgrading to 1.0.6 or even lvm2 help my situation? Can someone please help me get my system back to being operational?
