Subject: Re: How to fix missmatch between VG-size and LV-size?
SNIP>
I can run LVM commands fine now after the reboot and the output from
pvdisplay and lvdisplay is like i posted earlier.
How can i revert this in a safe way? I was thinking of just removing the
PV and do a vgcfgrestore to "before" the lvextend.
But since lvdisplay says the volume is 4.16TiB and pvdisplay says 5.59TiB
something is wrong? Or am I missing something?

Is it better to do a e2fsck now?
That is probably the only way to salvage what is left of your filesystem,
but don't do it until we find out whether the LV is the old or the new
size.
I suspect the LV will be the new size, but the filesystem may still show
the old size. Since the resize2fs should be just adding free space, there
may not be any data loss. e2fsck would fix the (now corrupt)
free space, and you can extend again.
I just added all the segments of the LV from an old backed up config file.
It adds up to 3,856TB, so I guess you were right and i assumed wrong. The
old LV was about 3,8TB and the new is about 4,16TB or about 400GB bigger
than before as expected by lvextend -L+400G.
Also it tells me I have 1,43TiB free wich is 5,59TiB - 4,16TiB. It also
looks right.
maybe I should try an e2fsck now?
again, thanks for your time
