Three days ago I installed Devuan chimaera on a clean computer, made two partitions: / and /home with the jfs file system on a SATA hard drive
My fstab:
/dev/sda1/jfs defaults,noatime 0 1
/dev/sda3 /home jfs defaults,noatime 0 1
/dev/sda2 none swap sw 0 0

After shutdown with the shutdown -h now command, the computer takes a very long time to complete the fsck check, and usually even after an incorrect shutdown it is much faster, and shows an error
logredo failed (rc=-274). Fsck continuing
**Phase 1 - Check Blocks
**Phase 2
**Phase...
**Phase 9 -Reformat File system log
...
Filesystem is clean
After which it successfully mounts the disk.

In this case, checking the /home partition proceeds quickly as usual.

I loaded liveusb, checked jfs_fsck /dev/sda1, /dev/sda3 - everything was fast, without warnings or errors.

I noticed that if you turn it off not through shutdown, but through poweroff and reboot, the computer boots as always quickly without warnings or errors.
