Correction. This volume is working fine with 42.2 release kernel and all
maintenance kernel until 4.4.62-18.6-default (included).

It is no longer mountable with latest maintenance kernel

with 4.4.62-18.6-default kernel:
# lsblk -b /dev/sdb
NAME   MAJ:MIN RM          SIZE RO TYPE MOUNTPOINT
sdb      8:16   0 1000204886016  0 disk 
������sdb1   8:17   0 1000203820544  0 part /mnt/cache

No, this is a disk I added to my system a long time ago (either with openSUSE
13.1 or 42.1, I'm not 100% sure), I don't remember doing any replace operations
on it.
