[ovirt-users] Failed to activate Storage Domain --- ovirt 4.2
Hi Has anyone experiencing the following issue with Storage Domain - Failed to activate Storage Domain cLUN-R940-DC2-dstore01 -- VDSM command ActivateStorageDomainVDS failed: Storage domain does not exist: (u'1b0ef853-fd71-45ea-8165-cc6047a267bc',) Currently, the storge Domain is Inactive and strangely, the VMs are running as normal. We can't manage or extend the volume size of this storage domain.

The Storage Domain was the master domain and it ran out space. ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/4Y6LEK5RZE33HDLZQXBJ4IODUKDI67R5/

Hi Nir Yes, the metadata was corrupted but the VMs were running OK. This master storage domain has increased its allocation significantly overnight and ran out the space limit and went to offline completely. The cluster was online and VMs were running OK but the affected Storage Domain went offline. I tired increase the storage domain but the Ovirt wasn’t allowing to expend the storage. Due to time constrain, I had restore the storage domain using Compellent snapshot. However, we need to prevent this happening again when Master storage Domain fill-up with the space. Currently, we have the following parameter set in the 5TB storage Domain.

Yes, the second metadata area, at the end of the device is corrupted; the first metadata area is probably ok. That version of lvm is not able to continue by just using the one good copy. Can we copy the first metadata area into the second metadata area? Last week I pushed out major changes to LVM upstream to be able to handle and repair most of these cases. So, one option is to build lvm from the upstream master branch, and check if that can read and repair this metadata. This sound pretty risky for production. > David, we keep 2 metadata copies on the first PV. Can we use one of the > copies on the PV to restore the metadata to the least good state? pvcreate with --restorefile and --uuid, and with the right backup metadata What would be the right backup metadata? could probably correct things, but experiment with some temporary PVs first. Aminur, can you copy and compress the metadata areas, and shared them somewhere? To copy the first metadata area, use: dd if=/dev/mapper/360014058ccaab4857eb40f393aaf0351 of=md1 bs=128M count=1 skip=4096 iflag=skip_bytes To copy the second metadata area, you need to know the size of the PV. On my setup with 100G PV, I have 800 extents (128M each), and this works: dd if=/dev/mapper/360014058ccaab4857eb40f393aaf0351 of=md2 bs=128M count=1 skip=799 gzip md1 md2 Nir ___ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-le...@ovirt.org Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/ZCD5K4UTMZ3QVS7OC2KWBSXWCHWTXQLV/
[ovirt-users] Windows 2016 guest auto shutdown
I am using ovirt hosted engine 4.2 to manage 5 nodes cluster and Dell Compellent storage domain using ISCSI. The guest is running Windows 2016 OS with ovirt 4.2.4 guest tools installed. The guest presented 1.4 TB thin provision disks and very often, the VM goes offline while doing big file transfer. I didn't find any event errors on OS level. I am wondering if anyone has experienced this issue.

The VM guest has a single network port and the host has multiple ports for managements, ISCSI and it can’t be run everything on a single network as 20 more guests are running on the same host.

[ovirt-users] After attaching the Storage domain, the VMs are disappeared from the VM import
Hi, We're noticing some weird issue while re-attaching the storage domain. After re-attach the storage domain, some VMs are completely missing from the VM Import. Before detaching the storage domain, all the VMs were shutdown gracefully. I also noticed some disks are exists with no Alias under the disk import on the storage domain and I can't import those disks. Its failed to register the disk with error. We're using Ovirt 4.2 with multiple Dell hosts in the cluster and Compellent SAN with iSCSI volumes. Please kindly advise if I am missing anything before detach the storage domain.
