[solved] 0.5.31 -> 0.5.32 ": "net.inet.tcp.delayed ..."

I wanted to upgrade to the latest version (0.5.32) and got this error:

openmediavault (0.5.32) wird eingerichtet ...
Updating configuration ...
error: "net.inet.tcp.delayed_ack" is an unknown key
error: "net.inet.tcp.recvspace" is an unknown key

Kernel: 3.2.0-0.bpo.4-amd64
I'll try the 2.6-kernel and report back. Anyone having this error, too?

Update:
I can't find the source of the problem. With Kernel 2.6 the installation gives the same error
Where is the file, where these net.inet.tcp-things are configured?
I looked into:
/etc/sysctl.d
usr/share/openmediavault/mkconf
/var/lib/dpkg/info
and others ...

Update #2:
It was /etc/sysctl.conf
I commented out this entries:

#net.inet.tcp.delayed_ack=0
#net.inet.tcp.recvspace=40960
#net.inet.tcp.rfc1323=0

and it worked. I don't remember, if I made theese changes by myself, but it worked before 0.5.31 since a looooong time.

It worked before Wasn't sysctl not executed before at boot or upgrade? I always thought sysctl is executed after/while booting? :shock:

If a user modifies the sysctl-values and it gives errors, wouldn't "-e" help? Then users could upgrade without an error in the future ...
from "man sysctl"

Zitat

-e
Use this option to ignore errors about unknown keys.

I know, OMV is for "normal" users, who don't modify the sysctl.conf, but shouldn't it be also "rock solid" and stable (for the other ones)? :roll:
