CentOS - Jan 2021 - rare but repeating system crash in C7

Hi Fred,

do you use automatic umount for the map in /etc/auto.master (--timeout) ?

If yes, then the systemd mount options probably won't help.

Best Regards,

Yeah, and the instructions for setting RAID-1 or RAID-0 have the switch
positions exactly reversed.

Strahil: I'm using autofs to automount the unit. but just turned that off
and enabled the xsystemd.automount in fstab, we'll see how that works.

Strahil:

I WAS using that, but the automatic umount never worked, leaving it mounted
all the time.

I commented out those entries in /etc/auto.master before modifying the
fstab entry:

UUID=259ec5ea-e8a4-465a-9263-1c06217b9aaf       /mnt/backup
ext4,x-systemd.automount,x-systemd.idle-timeout=15min   noauto  0       2

which is exactly as it was before except for the x-systemd entries as you
described.

and the peculiar thing is it STILL does not automount. and yes, I did do
systemctl restart local-fs.target.

do I need to reboot (or something simpler, maybe) to fully disable the
auto.master stuff?

Thanks again!

Fred
