[ovirt-users] Adding direct lun from API doesn't populate attributes like size, vendor, etc
Using this python I am able to create a direct FC lun properly (and it works if
the lun_id is valid). But in the GUI after the disk is added none of the
fields are populated except LUN ID (Size is <1GB, Serial, Vendor, Product ID
are all blank).
I see this Bugzilla [1] is very similar (for iSCSI) which says the issue was
fixed in 3.5.0, but it seems to still be present in 3.5.1 for Fibre Channel
Direct Luns at least.
Here's the python I used to test:
lun_id = '3600a098038303053453f463045727654'
lu = params.LogicalUnit()
lu.set_id(lun_id)
lus = list()
lus.append(lu)
storage_params = params.Storage()
storage_params.set_id(lun_id)
storage_params.set_logical_unit(lus)
storage_params.set_type('fcp')
disk_params = params.Disk()
disk_params.set_format('raw')
disk_params.set_interface('virtio')
disk_params.set_alias(disk_name)
disk_params.set_active(True)
disk_params.set_lun_storage(storage_params)
disk = api.disks.add(disk_params)

[ovirt-users] Moving HostedEngine from one Cluster to another
My HostedEngine exists in the Default cluster, but since I'm upgrading my hosts to RHEL7 I created a new Cluster and migrated all the VMs to it (including HostedEngine). However in the GUI VM Tab HostedEngine still appears as in the Default Cluster. Because of this I can't remove this cluster (it thinks there's a VM in it) even though there are no more hosts or VMs in it. I also can't change the cluster of HostedEngine, it says Cannot edit VM Cluster. This VM is not managed by the engine.

Re: [ovirt-users] Benefits of Cluster separation
We only have about 200 VMs, but we’ve run into this bug [1] because we use a high number of direct attach luns on our VMs. It takes about 5 minutes to scan all the fibre channel luns (same issues exists with iSCSI) and used times out before completing (until we changed the value of vdsTimeout higher). Also because of the way our FC storage is presented, we have about 1,400 multipath devices presented to each host. This contributes to really long scan times and I think causes some general slowness in administration side and “Bad Request” 500 Errors when running some storage commands from the API. VMs themselves still run just fine with no noticeable performance issues though.

I made this change yesterday and so far so good. Hi, no serious issue can be caused by that. Keep in mind though that any other operation will have that amount of time to complete before failing on timeout - which will cause delays before failing (as the timeout was increased for all executions) when not everything is operational and up as expected (as in most of the time). I'd guess that a RFE could be opened to allow increasing the timeout of specific operations if a user want to do that. thanks, Liron. if you have HA vms and use power management (fencing), this might cause longer downtime for HA vms if host has network timeouts: the engine will wait for 3 network failures before trying to fence the host, so in case of timeouts, and increasing it to 5mins, you should expect 15mins before engine will decide host is non-responsive and fence, so if you have HA vm on this host, this will be the vm downtime as well, as the engine will restart HA vms only after fencing. you can read more on http://www.ovirt.org/Automatic_Fencing Even I am in a need where, I try to delete all the 256 gluster volume snapshots using a single gluster CLI command, and engine gets timed out. So, as Liron suggested it would be better if at VDSM verb level we are able to set timeout. That would be better option and caller needs to use the feature judicially :) Please open a RFE for being able to set operation timeout for single command call with description of use cases for which you would like to set the timeout.

Re: [ovirt-users] hosted engine , how to make changes to the VM post deploy
I went through this a couple months ago. Migrated my hosted-engine from one NFS host to another. Here are the steps that I documented from the experience. There is probably a better way, but this worked for me on two separate hosted-engine environments. 1. Make a backup of RHEV-M 2. Migrate VMs off all hosts that run hosted-engine (except hosted-engine itself) 3. Put hosted-engine hosts in maintenance mode (except host that's running hosted-engine) 4. Put hosted-engine in global maintenance mode 5. Shutdown hosted-engine 6. Stop ovirt-ha-agent and ovirt-ha-broker services on all hosted-engine hosts 7. On each hosted-engine host: a. service ovirt-ha-agent stop b. service ovirt-ha-broker stop c. sanlock client shutdown -f 1 d. service sanlock stop e. umount /rhev/data-center/mnt/hosted-engine-share f. service sanlock start 8. mount new NFS share on /hosted_tgt 9. mount old NFS share on /hosted_src 10. Copy data (make sure sparse files are kept sparse): a. rsync --sparse -crvlp /hosted_src/* /hosted_tgt/ 11. Edit /etc/ovirt-hosted-engine/hosted-engine.conf and change path: storage=10.1.208.122:/HostedEngine_Test 12. Make sure permissions are vdsm:kvm in /hosted_tgt/ 13. umount /hosted_tgt 14. umount /hosted_src 15.

Re: [ovirt-users] vmware type functionality
Yep, note that it's a little different from VMWare in that it takes a snapshot for each disk in the VM to do a live storage migration, and the snapshots can't be deleted while the VM is powered up (in 3.4 at least).

[ovirt-users] Moving hosted-engine NFS storage
I'm planning on moving my hosted-engine storage from one NFS server to another shortly. I was thinking it would be relatively simple: 1. Stop hosted-engine 2. Copy existing share to new nfs share 3. Edit /etc/ovirt-hosted-engine/hosted-engine.conf and change storage to the new address 4. Restart hosted-engine services on hosts 5. Restart hosted-engine However online reading says that this won't work because the storage domain info is stored in different places. Is there a procedure or anything for how to do this?

Re: [ovirt-users] How to backup/restore the rhevm-VM in hosted-engine ?
In my case I actually have a spare server (physical) that I keep patched and up-to-date, the engine backups are automatically transferred there. If my hosted-engine goes down I restore the engine database on the physical spare and run like that until I can get the hosted-engine back up. I’ve never tried restoring onto a newly deployed hosted-engine VM using hosted-engine --deploy, but I can’t see why that wouldn’t work (maybe someone else knows if this is possible?).

Thanks for the reply! So when keeping a snapshot for a long time I have to keep an eye on how large it will get over time. The snapshot's size itself is determined when it's taken according to the disks size at the time. It then stays the same. When taking a snapshot, the active image of the disk is frozen at this point in time, and a new, empty active image is created to hold the new data on the disk. The new data is saved in the form of diffs, so if there are mainly additions to the snapshot time, the space difference of the snapshot is negligible. But if the diffs include many reductions from the snapshot's state - this might consume a lot of space, again, depending on your usage. Note that you're also limited by the disk's size. But there's no (or very little) performance impact or potential issues from keeping snapshots (other than the storage pool filling up maybe)? All the vm operations take into consideration snapshots. Storage is an issue, but so is every operation you'll make on the vm. When you have one image, the vm is handled only through this image. But when you have several, for each operation the right layer will search for the existence/ability to do the operation in all the snapshots (worst case). So there is in fact an impact, but it's due to the mere existence of the snapshots and their number, not their age. We support 26 snapshots per VM, but you should only use it if you actually need the backup. If you need RT performance, try to avoid it as possible.

Ryan, Disk snapshots consume fixed storage space (fixed since time of creation). The more differences there are from on your disk since the snapshot was taken, the more space is consumed, but that happens with no relation to the snapshot. If your frequent changes are in the form of adding data to you disks (on top of data snapshot time), then the space consumption of the snapshot is negligible. If you are undoing stuff from the snapshot time, there is actually more space consumed (to save the differences), otherwise the space would have just been released.
