Comment 1 David Teigland 2021-02-08 18:07:26 UTC 
Hi, could you please attach the output of the following?

pvs -vvvv
ls /sys/dev/block/259:0/
ls /sys/dev/block/259:1/
ls /sys/dev/block/259:2/
ls /sys/dev/block/259:3/
ls -l /sys/dev/block/259:1
ls -l /sys/dev/block/259:2
ls -l /sys/dev/block/259:3
cat /sys/dev/block/259:1/partition
cat /sys/dev/block/259:2/partition
cat /sys/dev/block/259:3/partition


An example of what I'm looking for, taking from a test machine in our lab:

$ ls -l /dev/nvme0n1p1
brw-rw----. 1 root disk 259, 3 Jan 19 14:30 /dev/nvme0n1p1

$ ls /sys/dev/block/259:3/

$ cat /sys/dev/block/259:3/partition
1

$ ls -l /sys/dev/block/259:3
lrwxrwxrwx. 1 root root 0 Nov 18 14:26 /sys/dev/block/259:3 -> ../../devices/pci0000:00/0000:00:1c.4/0000:03:00.0/nvme/nvme0/nvme0n1/nvme0n1p1
Comment 2 David Teigland 2021-02-08 18:15:53 UTC 
Note that this bug likely appeared as a result of the fix in bug 1859659 to recognize multipath nvme.

Comment 4 David Teigland 2021-02-09 16:11:13 UTC 
Thanks for the info, it was a bug in the fix for bug 1859659.
fix in main branch
https://sourceware.org/git/?p=lvm2.git;a=commit;h=f74f94c2ddb1d33d75d325c959344a566a621fd5
Comment 5 David Teigland 2021-02-09 17:36:56 UTC 
I managed to reproduce these errors (without the fix) by running pvcreate on an md partition.
- fdisk /dev/md0
- create partitions
- pvcreate /dev/md0p1
- readlink errors printed

Existing lvm tests do this but the readlink errors are non-critical so they don't cause the command to fail or do anything wrong.
Comment 10 Corey Marthaler 2021-02-16 22:59:39 UTC 
Fix verified in the latest rpms.
