Do you see any dmesg kernel errors when you try to activate the LVs?

Gruss

Betreff: [linux-lvm] lvm raid5 : drives all present but vg/lvm will not assemble


This started on a Raspberry PI 4 running raspbian.  I moved the disks to my Fedora 31 system, that is running the latest updates and kernel.  When I had the same issues there I knew it wasn't raspbian.

I've reached the end of my rope on this. The disks are there, all three are accounted for, and the LVM data on them can be seen.  But it refuses to activate stating I/O errors.

[root@hypervisor01 ~]# pvs

  gluster02 vg1               Rwi---r--- 14.55t

The one in question is the vg1/gluster02 lvm group.

I try to activate the VG:
[root@hypervisor01 ~]# vgchange -ay vg1
  device-mapper: reload ioctl on  (253:19) failed: Input/output error
  0 logical volume(s) in volume group "vg1" now active

I've got the debugging output from :
vgchange -ay vg1 -vvvv -dddd
lvchange -ay --partial vg1/gluster02 -vvvv -dddd

Just not sure where I should dump the data for people to look at.  Is there a way to tell the md system to ignore the metadata since there wasn't an actual disk failure, and rebuild the metadata off what is in the lvm?  Or can I even get the LV to mount, so I can pull the data off.

Any help is appreciated.  If I can save the data great.  I'm tossing this to the community to see if anyone else has an idea of what I can do.
