The given answer: Resolution
Please upgrade to RHV 4.4 SP1. Newer improvements greatly reduced the delays during extensions and the default values were changed to accomodate modern hardware. The tuning suggested below should be reverted after upgrading to RHV 4.4 SP1, in case it was applied. Recent testing shows the latest RHV 4.4 SP1 can handle up to 1300MiB/s of writes without pausing. If the VM is expected to constantly write values around or higher than this, please use RAW preallocated volumes. > Le 4 nov. 2024 à 12:19, José Ferradeira via Users <users@ovirt.org> a écrit : > > Hi, > > I found this: https://access.redhat.com/solutions/130843 > But have no access. > > Any help? > > Thanks > José > > From: "José Ferradeira via Users" <users@ovirt.org> > To: "Jean-Louis Dupond" <jean-lo...@dupond.be> > Cc: "users" <users@ovirt.org> > Sent: Wednesday, August 21, 2024 11:27:47 AM > Subject: [ovirt-users] Re: VM has been paused due to no Storage space error. > > Hi, > Ok, discard is not enabled on the disk. > Reading https://gitlab.com/qemu-project/qemu/-/issues/1621 > > I'm sure the image did not grow over 110% of its virtual size > > Any idea? > > Thanks > José > > From: "Jean-Louis Dupond" <jean-lo...@dupond.be> > To: supo...@logicworks.pt > Cc: "users" <users@ovirt.org> > Sent: Wednesday, August 21, 2024 10:17:22 AM > Subject: Re: [ovirt-users] VM has been paused due to no Storage space error. > > Hi, > > Not talking about discard on the storage domain, but on disk/vm level. > Is it enabled there? > > Cause if that is the cause, it could be > https://gitlab.com/qemu-project/qemu/-/issues/1621 > > On 21/08/2024 11:14, supo...@logicworks.pt <mailto:supo...@logicworks.pt> > wrote: > Hi Jean-Louis, > > The VM disk is 300GB with 216GB available, preallocated on a iSCSI storage > with 3532GB total and 1932GB free. > Have enable incremental backup.
