synoacl? I cannot find that mount option: are you on a Synology NAS?

AFAIK stripe=32 should not have any impact on mtime, nor data=writeback

I'm using Guix on Debian and my store is in a LV too:

--8<---------------cut here---------------start------------->8---
/dev/mapper/vg01-gnu on /gnu type ext4 (rw,relatime)
--8<---------------cut here---------------end--------------->8---

I vaguely recall once I had one problem with source scm files newer than
compiled when using ./pre-inst-env (for sure I did something wrong
hacking, not directly touching /gnu/store anyway) but "guix gc
--verify=repair" fixed that for me

Ricardo also asked you about the daemon: how is it started on your
machine?

mine is starded by the systemd service (installed via binary
installation), and is running as root:

--8<---------------cut here---------------start------------->8---
host:~$ ps aux | grep guix-daemon
root      2444  0.0  0.0  12216  1808 ?        Ss   Mar22   0:00 /var/guix/profiles/per-user/root/current-guix/bin/guix-daemon --build-users-group=guixbuild
--8<---------------cut here---------------end--------------->8---

[...]

HTH! Gio'
