So does this mean I shouldn't bother with installing otopi, because according to the development guide for RPM-based systems, it seems only the ovirt-host-deploy, ovirt-setup-lib, and ovirt-js-dependencies are the packages required. The guide for Debian is blank and marked as TODO. Another query I had was that should I make the config files myself as referenced by the README or can I expect that it will be done during make install? -- - Warm regards Leni Kadali Mutungi ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] storage redundancy in Ovirt
When you set up a storage domain, you need to specify a host to perform the initial storage operations, but once the SD is defined, it's details are in the engine database, and all the hosts get connected to it directly. If the first host you used to define the SD goes down, all other hosts will still remain connected and work. SPM is an HA service, and if the current SPM host goes down, SPM gets started on another host in the DC. In short, unless your actual NFS exporting host goes down, there is no outage.

Re: [ovirt-users] storage redundancy in Ovirt
I think he means SPM? I've seen when node with SPM goes down it isn't really seamless and takes a minute or two to catch up unless of course you out that node in maintenance mode but that isn't possible if it crashes or something On Apr 15, 2017 1:38 PM, "FERNANDO FREDIANI" wrote: > Hello Konstantin. > > That doesn`t make much sense make a whole cluster depend on a single host. > From what I know any host talk directly to NFS Storage Array or whatever > other Shared Storage you have. > Have you tested that host going down if that affects the other with the > NFS mounted directlly in a NFS Storage array ? > > Fernando > > 2017-04-15 12:42 GMT-03:00 Konstantin Raskoshnyi : > >> In ovirt you have to attach storage through specific host. >> If host goes down storage is not available. >> >> On Sat, Apr 15, 2017 at 7:31 AM FERNANDO FREDIANI < >> fernando.fredi...@upx.com> wrote: >> >>> Well, make it not go through host1 and dedicate a storage server for >>> running NFS and make both hosts connect to it. >>> In my view NFS is much easier to manage than any other type of storage, >>> specially FC and iSCSI and performance is pretty much the same, so you >>> won`t get better results other than management going to other type. >>> >>> Fernando >>> >>> 2017-04-15 5:25 GMT-03:00 Konstantin Raskoshnyi : >>> Hi guys, I have one nfs storage, it's connected through host1. host2 also has access to it, I can easily migrate vms between them.

Re: [ovirt-users] storage redundancy in Ovirt
Hello Konstantin. That doesn`t make much sense make a whole cluster depend on a single host. >From what I know any host talk directly to NFS Storage Array or whatever other Shared Storage you have. Have you tested that host going down if that affects the other with the NFS mounted directlly in a NFS Storage array ?

Re: [ovirt-users] storage redundancy in Ovirt
In ovirt you have to attach storage through specific host. If host goes down storage is not available.

Re: [ovirt-users] storage redundancy in Ovirt
Well, make it not go through host1 and dedicate a storage server for running NFS and make both hosts connect to it. In my view NFS is much easier to manage than any other type of storage, specially FC and iSCSI and performance is pretty much the same, so you won`t get better results other than management going to other type.

You can use FC storage where luns come from a redundant storage array.

[ovirt-users] Memory ballooning not working on RHEV 4.1?
Hello all, I have a RHEV 4.1 host running Windows 10 VMs. I have installed the balloon driver on the VMs (RHEV guest tools), and enabled memory ballooning on the cluster using RHEV-M. On the VMs, I have set the system memory to Memory Size: 4GB, Maximum Memory: 16GB. While I can manually hot plug memory, I am not seeing additional memory being automatically allocated to the VMs during a SQL workload. The documentation for RHEV 4.1 is not clear on whether or not this automatic ballooning is functional (earlier documentation suggests that it is functional only by use of an API). I am new to RHEV and would appreciate some help troubleshooting this. Please let me know if there's any additional information I should provide. I messaged this mailing list on suggestion from someone in the IRC. I hope this is in-bounds.
