Web Gui - stopped working - dial tcp: lookup omv on 127.0.0.1:53: no such host

    • Web Gui - stopped working - dial tcp: lookup omv on 127.0.0.1:53: no such host

      Dear Sirs/Madams,

      I recently upgraded to version 4, and have had tons of problems with my mdraid.

      My raid is now ok (at least the 4 disk raid5 i originally had)

      But i have since added another 5 disks to my system, and that raid is visible locally on the omv box, but i cannot see that export on my remote systems

      so this morning i was going to check over my shared folder etc in the omv GUI, only to find out the we gui no longer works :(

      i only get this message in my browser :

      dial tcp: lookup omv on 127.0.0.1:53: no such host

      And did this procedure :

      Which removed the error message, but the webgui still wont display

      Hi mrpg,
      are there any other interfaces available? It could be the case that the web server is offering its services ("listen to traffic") on another interface. IP 127.0.0.1 sounds like a loopback device.
      Many thanks fot your reply, sorry for my slow response, i have been to busy @ work.

      i input 192.168.0.112 into my browsert on my laptop to access the omv web gui of my nas , which has that ip address.

    • Something is terribly wrong with this new version of omv.

      i have had zero problems for 2 years, and i thought, it would be cool with a new version, perhaps there are new useful features & even performance improvements.

      1 i stil have issues with my /dev/md127 device, its hangs the omv box if i list directories on certain folders
      2 i it hangs when i run :

      Source Code

      1. e2fsck -y /dev/md127

      3 this threads subject, web gui no longer works

      is my machine dying? hw wise , i get nothing in dmesg or /var/log/messages or /var/log/syslog that is suggesting a hw problem.

      i have a new pc i could move my disks to, can anybody reckommend a step by step instruction for moving 4 disk mdraid5 & 5 disk mdraid5 to a new omv install without loosing data?

      these forums seems to be very inactive, i just want some help along the way.

      Seems underpowered or just not happy with the newer kernel. What system is it again?

      80 posts a day seems decent to me. Personally, I just don't have much time to devote to the forum and even less since I am trying to port the omv-extras plugins to OMV 5.x.

      t is underpowered and old, but i have zero load on my cpus and zero load on my disks.


      its a Hewlett Packard workstation xw8200 with 2x Intel(R) Xeon(TM) CPU 3.40GHz and 4gb ram

      Sure but what is the new system? And using mdadm seems to be the biggest issue with your system. Why are you using raid? I hope you aren't using it as backup (since it is not).

      I am using raid because
      1 it is more redundant then using a single disk
      2 it creates a big logical disk from several smaller disks.

      The new system is an i7 intel CPU with 32gb ram nvme disk for Inc

      I will also use this system to run virtual machines on.

      True but most home users don't need that kind of redundancy (I don't use raid). And it seems like your current outage isn't the end of the world :)

      mergerfs/unionfilesystem plugin does that as well. You can't have a file bigger than a single disk but that usually isn't a problem. I use this plugin on quite a few of my systems.

      That should work much better. You should be able to move your disks including the OS disk to the new system, set the OS disk to boot, and it just works. Since the network adapter will be different, you should run omv-firstaid to fix that. But other than that, the move is pretty simple.

      cockpit works pretty well for that.

      Sounds good!

      So it does not matter that the sata cables are connected in a different port or different sata controller? Mdraid will pickup the member disks anyway?

    • Sounds fantastic,

      i am on a work trip at the moment, but will build the new pc , hopefully next week.

      the /dev/md127 mdraid does not seem happy at all,

      it hangs if i try to fsck on it

      it hangs if i try blkid

      anything one can try to get that going again on this machine?

      Wipe the disks and recreate it. I've never had this issue so I haven't had to fix it much.

      I wouldn't assume that it won't work on the new machine. I think the array can be made to work on the machine but it might not want to assemble on every reboot.

    • Hello,

      looks like i need your expertise again @ryecoaaron

      i have finally had time to build my new pc.

      i am now suspecting either my sata controller card, or disks, i mean something is smelling quite fishy here,

      So i built a new pc :

      asus z390 mainboard
      intel u7 8700
      32gb ddr4 2666
      intel nvme disk for omv

      so far i have only added my 4x disk raid 5 to the system, i am waiting to connect my 5x ssd zfs raid.

      installed omv 5.05

      and i cant even open the web gui, its just telling me "loading please wait"

      i can login through ssh no problems, no load or disk activity..

      what is goiing on? , please help..
