slow shutdown: remaining crypto disks busy failed

I've added new luks partition put it in fstab and crypttab. The system boots with no problem. The partition behaves as expected, but when I reboot/shutdown I get this message:
stopping remaining crypto disks...sdb5_crypt (busy)...
stopping early crypto disks ...sdb5_crypt (busy) ...failed.
done.

What is this? How can i get rid of it? It takes time and not sure it's good for file system. The luks partition is not yet in use, just clean and ext4 formatted.

Beowulf? Then you need to patch a file. Gone with Chimaera.

For the patch read this please: https://dev1galaxy.org/viewtopic.php?id=1753

no, chimaera
lsof gives nothing. Suppose the system itself keeps cryptsetup.
The problem appears only when I create lvm on luks and attach it. Just encrypted partition (no lvm on it) is ok. Have checked.

Re: slow shutdown: remaining crypto disks busy failed

Well, the symptoms are similar to the ones I had with ASCII and Beowulf. Encrypted LVMs were not shut down correctly.

When you see this problem with Chimaera I guess something along the cryptsetup packages is missing on your machine. I have installed:

cryptsetup
cryptsetup-bin
cryptsetup-initramfs
cryptsetup-run
libcryptsetup12
udisks2

HTH, rolfie

Effectively, this one was not installed. Will try to recreate lvm on luks to check. Thanks.

Re: slow shutdown: remaining crypto disks busy failed

After all if overlay fs is mounted on top of luks partition chimaera becomes locked on shutdown for ~half a minute.
Probably the bug is not solved completely in debian/devuan. ?

Re: slow shutdown: remaining crypto disks busy failed

Well, I have several luks2 encrypted LVMs with ext4/swap running under Chimaera, no delays. As well upgrades from Beowulf as native installs.

What do you mean by overlay fs?

Mean "/" is mounted like    /dev/mapper/mycrypt  /overlay/ro

Works fine but cannot shutdown correctly.
