Ok. It sounds like the fix will have to involve finding a way to get
back to your installed-configuration. The one that defines your VG as
containing *only* hda5 and hdb. It sounds like you succeeded extending
the LV to include sda, but forgot to expand the filesystem after that.
Which, ultimately, may save you. I don't have enough experience with
LVM (or just LVM2) to be able to tell you either how to edit your
current mangled config to force your LV to forget about sda (which it
sounds like you were successful accomplishing anyways) *or* to recover
the before-sda configuration. I've looked at the config on my own
workstation and even though I'm using LVM2 I don't see any evidence of
backed-up or historical LVM2 configuration data. So I *really* don't
know what to tell you there. But I think it should be do-able. There
may be someone out there capable of helping with this, but I'm afraid
it likely isn't me. Although I might try and reproduce this on one of
my Fedora machines to see if I get stuck in the same box which you are
I had a bad drive in my volume group, so I tried "vgreduce --removemissing VolGroup00" which seemed to work. Then, I tried "vgchange -ay --partial VolGroup00" which also appeared to complete successfully. It seems like I was partly successful but I cannot get the logical volume to be recognized. I don't know what else to do? Where can I learn more about LVM? How does one utilize the LVM archive or backup files? Can't seem to find an answer to this problem. Is all of my data lost?
