Hi @g6094199, can you please try this server:

ntp1.inrim.it

next step, from shell run cat /etc/nsswitch.conf | grep hosts and please post here your output

Can you ping ntp servers? no -> dns missing?
yes -> we have to check from shell
ntpdate 1.de.pool.ntp.org
ntpdate -d 1.de.pool.ntp.org
ntpdate -u 1.de.pool.ntp.org

After that i tried to add the NTP sever to the web-if again and it worked! maybe there is a problenm with the ntpd, not beeing stoped correctly. i couldnt stop it with systemctl thats why i killed it.

now its status is:

hi!

Since im having some other problems to i played around with the system.
disabled ntp rebooted, tried to restart ntp -> same error.
now it tried to ping the ntp servers and an “memory access error” occurs (“speicherzugriffsfehler” in german)

[root@rockstor ~]# route
Kernel IP Routentabelle
Ziel Router Genmask Flags Metric Ref Use Iface
Speicherzugriffsfehler
[root@rockstor ~]# ping 1.pool.ntp.org
Speicherzugriffsfehler

so i guess there is another problem beeing involved.
this is a freshly installed VM with a 3.8-15 cd from sf and online updated to 3.8.16-6

did also an fresh install with the same error.
now it try to reinstall with the lastest 3.8-16-1 to see if anything changes.

Hi @g6094199,
Speicherzugriffsfehler is Segmentation fault, what I suspected on my previuous message asking if you can ping

This is a CentOS related issue currently with tracking over CentOS and Samba too

Solution:
on that forum link there’s a message with a trick to have ping and ntp running

Please note till Samba update from CentOS won’t be available, on every reboot you’ll have to manually start ntp service

Waiting your updates/checks :slight_smile:
M.

THX Mirko!

i did the easy fix and reinstalled with 3.8-15 and will do no updated till its fixed :wink:

9

Well @g6094199, you’d better stay on 3.8-16 (except on reboots you won’t suffer that CentOS bug on others)

M.

10

To all please update with yum update, major updates fixing samba segmentation fault over name resolution

Hi @g6094199,
Rockstor yum running with fastestmirror plugin so maybe your current mirror till without new packages (guessing)

M.

Edit: try with yum clean all && yum update

yep that fixed it.
i’m more of a debian guy so i wonder why yum doesnt pull the repo info without cleaning the cached data…

anyway

thx!

Hi @g6094199,
I’m a Debian guy too and I’m pretty sure yum has a kind of caching over repositories metadata (probably expiring every day?!?)
