Choosing Pete at random to look into this...
Comment 3 Pete Zaitcev 2001-03-06 15:18:57 EST
How did this happen? I am curious if the requestor run 
vgrename(8) or anything else has happened.
Pity that dmesg output was not saved.

Is the problem reproducible?

A silly omission. LOL

We are about to ship and LVM turned to be somewhat flakey.
The typo that I fixed for this bug is not the only one.
So, resolving into DEFERRED, even though this particular
fix is easy.

I'll see that mainstream kernel picks the fix. Won't help
LVM though until Heinz gets his act together.
Comment 6 Pete Zaitcev 2001-04-17 18:18:09 EDT
We went to 2.4.3-ac8 today and it has the fix in it.
I'll reopen and re-close with "Errata".
