HiThank you for the feedback, it was our IP subnet range (rented), which we have been paying for. They just gave it away and now, the new owners are refusing to give back our subnet, so now WE must make changes to our VMs networks. Its a very shitty story and they will soon regret this mistake they caused.

Hi Granwille, You need to ensure that IP range associated to CloudStack is not used by any other setup. If you have already done that and can't undo it but want to keep the remaining dedicated to CloudStack, you can mark the IPs allocated outside CloudStack as Allocated in the DB. Tangential point .... I believe you can't ping your VR's link local IP(169.254.X.Y) from your user VMs. That IP can only be reached by the underlying host and system VMs and VRs on the same host.

Can I please get the correct steps I can take to ensure the new range is correctly assigned to my VMs? is it as simple as unassigning an IP and re-assigning one again? And then obviously update the IP network in the VM? On 5/25/23 19:10, Simon Weller wrote: ok great. Glad you're making progress toward a resolution.

After we have been using it for MONTHS now. And I tested other VMs on the same HOST but they use a different subnet and they have full internet access. And the VMs not working are the ones with the missing subnet from my DC. I am busy fighting this now with them and will provide feedback if this was indeed the issue, but this far all fingers seems to point towards it.

However, VMs still have zero network. May I also add that I manually shutdown VMs in KVM using the virsh command. And then boot them up again via Cloudstack UI. Perhaps this has some affect.

Check the MySQL log and and also for any temp files that could be blowing out your disk usage . Are you running any MySQL replication? If so, make sure you have log rotation and deletion setup so they you only keep a few days of the replication logs. If you do see lots of binlogs, you can trim them using the FLUSH LOGS MySQL cli command. -Si On Thu, May 25, 2023, 10:45 AM Granwille Strauss<granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> <granwi...@namhost.com.invalid> wrote: Hi Guys I need any help I can get, please. I have a cloudstack management server and I configured NFS on it and have a few VMs that use this NFS as its primary storage. Today my VMs randomly just went down, no one did anything whatsoever. Upon review we found that the cloudstack management server drive shows its at 100% usage. But it makes ZERO sense. There is space, the drive is 872 GB big and only 840 GB is being used. So now, I managed to to move files and delete logs and so to try and free space. I deleted over 13 GB and still server shows 100% usage. But now I can finally log into Cloudstack UI, previously I couldn't. I am now moving those VMs volumes from the NFS to the local KVM disk. After successfully migrating the volume, I now boot the VM and it runs 100% fine, but there is ZERO internet access to the VM I cannot even ping google.com from the VM. SSVM and the virtual router are working 100% fine, zero failures on health check and also the SSVM check. The KVM host itself has full internet access. Any ideas? There are zero errors being thrown at all. -- Regards / Groete<https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> <https://www.namhost.com> Granwille Strauss // Senior Systems Admin *e:*granwi...@namhost.com *m:* +264 81 323 1260 <+264813231260> *w:*www.namhost.com<https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://www.facebook.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost> <https://twitter.com/namhost><https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/> <https://www.instagram.com/namhostinternetservices/><https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos> <https://www.linkedin.com/company/namhos><https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA> <https://www.youtube.com/channel/UCTd5v-kVPaic_dguGur15AA><https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> <https://www.adsigner.com/v1/l/631091998d4670001fe43ec2/621c9b76c140bb001ed0f818/banner> Namhost Internet Services (Pty) Ltd, 24 Black Eagle Rd, Hermanus, 7210, RSA The content of this message is confidential.
