Startup errors

xy16644 · Feb 1, 2014

When I run dmesg -a I have some errors I am unsure about:

Code:

/etc/rc: WARNING: $geli_swap_flags is obsolete.  Ignored.
kldload: can't load uhid: No such file or directory
Configuring keyboard: keymap.
kldload: can't load ums: No such file or directory

I setup my server to use encrypted swap as per the handbook as follows:

Code:

echo geli_swap_flags=”-e AES -l 128 -s 4096 -d”' >> /etc/rc.conf

Add the following to /etc/fstab:

Code:

# Device Mountpoint FStype Options Dump Pass#
/dev/da0p2.eli none swap sw 0 0
/dev/da1p2.eli none swap sw 0 0

Why am I getting the errors about the encrypted swap flags being ignored? Is it because I am running FreeBSD 10.0-STABLE and something has changed?

Not sure about the others for kldload either?

Specifying geli_swap_flags seems not to be necessary anymore. Just having *.eli entries for swap in fstab is enough (at least on 11-CURRENT, checked with geli list).

The kldload errors show up because the mentioned modules are missing from /boot/kernel/ (or whatever the output of sh -c '. /boot/loader.conf 2>/dev/null; echo /boot/${kernel:-kernel}' is on this box).

I have the following in the /etc/rc.conf:

Code:

keymap="uk.iso"
ahci_load="YES"

Would this be causing the kldload errors?

PS: Removing the geli entry from /etc/rc.conf has resolved the error for the encrypted swap...thanks!

I was just wondering, I use a bootable USB key to boot my FreeBSD server. When I try to reboot or shutdown the server it hangs when the USB key is plugged in. Could these errors be the cause of that?

Code:

kldload: can't load uhid: No such file or directory
kldload: can't load ums: No such file or directory

ahci_load is called ataahci_load nowadays and does not belong in /etc/rc.conf. It's used in /boot/loader.conf to load the corresponding kernel module. Since your system seems to run fine without it you probably don't need it.

So you boot from a USB stick? The old boot-from-stick-but-use-system-on-encrypted-drive-thing? What does ls -l /boot/kernel/{ums,uhid}.ko return?

xy16644 · Feb 1, 2014

Yes, I run /boot on a bootable USB key. The rest of the server is encrypted.

ls -l /boot/kernel/{ums,uhid}.ko gives:

Code:

-r-xr-xr-x  1 root  wheel    22K Jan 21 17:31 /boot/kernel/uhid.ko*
-r-xr-xr-x  1 root  wheel    26K Jan 21 17:31 /boot/kernel/ums.ko*

Make sure your stick's /boot and your system's /boot stay in sync! Just guess which /boot the kernel will access when it needs to load a module and the stick is not mounted...

I've only got one /boot.

ls /boot gives:

lrwxr-xr-x 1 root wheel 12B Jan 1 09:34 /boot@ -> bootdir/boot

I followed this guide when building the server:

I'm not sure I follow:

Apparently you have a different setup than I have. I have two /boot directories: one on a USB stick that's used to boot the system and another one on the system's encrypted drive. With such a setup if the two directories get out of sync you're in trouble.

Is there a way to stop the machine hanging if there is a USB key plugged in? Whenever I do a shutdown/reboot I have to hit the power switch as the console hangs.
