I have two proxmox machines, one is just for backup storage. We are changing our network up, changing domains, dns, etc. so I was trying to update the network configurations on my proxmox machines.
I started out by making some entries in host file and changing resolv.conf to include new domain and name servers. I did a reboot and lost connectivity.
On the backup server I set everything back like it was before and was able to get back connectivity. The other server however I cannot get working.
For interfaces I have:
auto lo
iface lo inet loopback
iface eno1 inet manual
auto vmbr0
iface vmbr0 inet static
address 10.1.5.9
netmask 255.255.255.0
gateway 10.1.5.1
bridge_ports eno1
bridge_stp off
bridge_fd 0
iface eno2 inet manual
iface eno3 inet manual
iface eno4 inet manual
for hosts I have:
# Auto-generated hostname. Please do not remove this comment.
127.0.0.1 localhost.localdomain localhost
10.1.5.9 sclsrv.scfuels.corp sclsrv
10.1.5.10 sclsrv2.scfuels.corp sclsrv2
10.1.5.12 datasrv.scfuels.corp datasrv
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
and for resolv.conf I have:
domain scfuels.corp
search scfuels.corp
nameserver 10.5.150.210
nameserver 10.5.120.210
the command ip addr gives similar to (this is from the working server but they seem to compare the same):
root@sclsrv2:~# ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eno1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vmbr0 state UP group default qlen 1000
link/ether 00:23:ae:9d:da:6a brd ff:ff:ff:ff:ff:ff
3: vmbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
link/ether 00:23:ae:9d:da:6a brd ff:ff:ff:ff:ff:ff
inet 10.1.5.10/24 brd 10.1.5.255 scope global vmbr0
valid_lft forever preferred_lft forever
inet6 fe80::223:aeff:fe9d:da6a/64 scope link
valid_lft forever preferred_lft forever
So what I notice is that eno1 is up and vmbr0 is up and showing that it has taken the ip address.
I have no ssh access and I can't ping anything. When I boot the server I get errors like "CIFS VFS: cifs_mount failed w/return code = -2 ..and then something about error connecting to socket. Then if I reboot the server it goes into some sort of recovery mode. In the recovery mode I am trying to get the connectivity working.
Any ideas?
