Luckily I have some backups of all but one LV (which is just too big to 
backup) on vol2. But it would be nice to recover that volume.

As far as syslog messages, I did not see anything out of the ordinary before 
the pvmove. Now of course I get the error message produced by vgscan which I 
pasted in the first message.

Not quite sure what you mean about "using vol2's content". I cannot get LVM 
to recognize vol2, so of course it will not activate it. So I cannot mount 
any of the volumes in vol2.

It is only complaining about /dev/vol2/software volume. If there was someway 
I could delete this volume without having to have vol2 activated, that might 
solve the problem--unless other volumes' metadata is corrupted as well. I 
seem to remember reading about LVM2's ability to do a partial activation 
(missing 1 or more PVs from a VG). Would it be worthwhile to try and mount 
vol2 under LVM2 with hdh3 removed?

Thanks,
Skip

Hello,

I'm trying to pvmove from a dying disk to a new disk.  I'm using version 1.0.7 
of the LVM tools.  I know that the source disk has bad sectors on it.  I 
figured one of two things would happen with the pvmove:
1)  pvmove would work fine up to the bad sectors, where it would error with 
I/O read errors.  I would then restart the pvmove with PEs that are past the 
bad sectors on the source disk and things would finish.
2)  pvmove would work fine up to the bad sectors, where it would encounter I/O 
read errors.  pvmove would report the errors and say the data is 
lost/corrupt, but continue reading valid/skipping bad sectors until it 
finished.
I fear that I'm being naive about how pvmove will handle bad sectors...  At 
any rate, the error I'm getting is:

Its linux 2.4.19 (with the sgi xfs patch) and lvm 1.0.6. I have two volumes, 
the other volume (vol1) is unaffected. All lvm operations seem to be working 
on vol1. For vol2 (the one that I executed a pvmove on), I cannot get lvm to 
recognize it so I cannot perform any lvm operations.

Which LVM and Linux  version is this ?
Does everything else irt LVM with the exception of pvmove ru fine
(i.e. creating/removing LVs etc.) ?

I am trying to remove an old harddrive from one of my volumes using:
  pvmove -v /dev/hdh3
It was chugging along just find until about half way through when it froze. 
Linux was not "frozen", but I do not think it would allow any io to the 
block devices (logins, ls's, etc would stall). I waited about an hour, at 
which point it was still stuck on the same extent, and had no other option 
but to hard reboot. When the system was booted, the volume to which hdh3 
belonged, would no longer mount:

$ vgscan
vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found active volume group "vol1"
vgscan -- only found 2523 of 768 LEs for LV /dev/vol2/software (1)
vgscan -- ERROR "vg_read_with_pv_and_lv(): allocated LE of LV" can't get 
data of volume group "vol2" from physical volume(s)
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume 
groups


Looks like some lvm metadata has been corrupted. So I ran vgcfgrestore on 
/dev/hdh3: same result. Then I ran it on all the PVs in vol2: same result. 
Does anybody have a solution to get this volume mounted? There is a bunch of 
data on vol2, but not all that much in /dev/hdh3, so a partial restore would 
be ok.

Thanks,
Skip
