I have two laptop with Devuan installed. When shutting down it hangs for about one minute when cryptsetup try to close the encrypted partitions.
Messages:
Stopping remaining crypto disks...sda5_crypt (busy)... failed.
Stopping early crypto disks...sda5_crypt (busy)... failed.
Partitions:
sda5
└─sda5_crypt
├─vg-root
├─vg-var
├─vg-swap_1
├─vg-tmp
├─vg-home
After tinkering with the scripts (/lib/cryptsetup/cryptodisks.functions), I know that LVM volumes are still active and I think it prevent cryptsetup from closing the partitions. If I add dmsetup remove_all before cryptsetup close partitions, most LVM volume are removed but vg-root remains, so it fail again.
