I am now seeing these errors on every shutdown. This is with a KVM virtual machine, where I previously never could produced the problem. And I do have "plymouth.enable=0".
IIUC use see these messages for a while, then they stop and the reboot succeeds (how long? how many messages)? If actually some library from the root FS was used by some process running outside of it, then the error should persist and the remove ioctl should consistently fail, causing the shutdown process to time out.
My personal opinion: this is all a mistake. The system should not try to disassemble device mapper setup.
I'm not sure where this happens. I guess it's the stop job of "blk-availability.service". Could you try to mask that service and see if the problem disappears? Wrt this being a "mistake", the blkdeactivate script was introduced to LVM by Red Hat in 2012. I didn't find an explicit rationale, but as they're unlikely to have written that code without a purpose, I guess they were seeing data corruption of some sort if it's not done. -- You are receiving this mail because: You are on the CC list for the bug.
