Re: Lost space in /var/log
by Michael Thomas 22 Jun '22

This can also happen with a misconfigured logrotate config. If a process is writing to a large log file, and logrotate comes along and removes it, then the process still has an open filehandle to the large file even though you can't see it. The space won't get removed until the process closes the filehandle (eg rebooting). The following command should give you a list of these ghost files that are still open but have been removed from the directory tree: lsof | grep '(deleted)' Stackexchange has some additional useful tips: https://unix.stackexchange.com/questions/68523/find-and-remove-large-files-… --Mike On 6/22/22 15:49, Matthew.Stier(a)fujitsu.com wrote: > Deleted some files to "clean up" /var/log, but the space was not recovered? > > Space for deleted files are only recovered when all references to that space are removed.

Create a file, open file-handle to it, and then remove the file. The open file-handle can then be written to, and read from, as long as you like, but when the file-handle is closed, explicitly or implicitly, the space is automatically recovered. > > > -----Original Message----- > From: Andrei Verovski <andreil1(a)starlett.lv> > Sent: Wednesday, June 22, 2022 3:27 PM > To: users(a)ovirt.org > Subject: [ovirt-users] Lost space in /var/log > > Hi ! > > I have strange situation with low disk space on /var/log/, yet I can't figure out what have consumed so much space. > Look at the du output. > > Thanks in advance for any suggestion(s). > > > # df -h > > Filesystem Size Used Avail Use% Mounted on > /dev/mapper/centos-var 15G 1.3G 13G 9% /var > /dev/mapper/centos-var_log 7.8G 7.1G 293M 97% /var/log > /dev/mapper/centos-var_log_audit 2.0G 41M 1.8G 3% /var/log/audit > > # > # du -ah /var/log | sort -n -r | head -n 20 > > 664K /var/log/vdsm > 660K /var/log/vdsm/vdsm.log > 624K /var/log/gdm > 580K /var/log/anaconda/storage.log > 480K /var/log/anaconda/packaging.log > 380K /var/log/gdm/:0.log.4 > 316K /var/log/anaconda/syslog > 276K /var/log/tuned > 252K /var/log/libvirt/qemu/NextCloud-Collabora-LVM.log-20210806 > 220K /var/log/Xorg.0.log > 168K /var/log/gdm/:0.log > 156K /var/log/yum.log-20191117 > 156K /var/log/secure-20180726 > 132K /var/log/libvirt/qemu/NextCloud-Collabora-Active.log > 128K /var/log/anaconda/anaconda.log > 120K /var/log/hp-snmp-agents > 116K /var/log/hp-snmp-agents/cma.log > 112K /var/log/vinchin > 104K /var/log/vinchin/kvm_backup_service > 104K /var/log/tuned/tuned.log.2 > > # > # find . -printf '%s %p\n'| sort -nr | head -10 > > 16311686 ./rhsm/rhsm.log > 4070423 ./cron-20180726 > 3667146 ./anaconda/journal.log > 3409071 ./secure > 3066660 ./rhsm/rhsm.log-20180726 > 2912670 ./audit/audit.log > 1418007 ./sanlock.log > 1189580 ./vdsm/vdsm.log > 592718 ./anaconda/storage.log > 487567 ./anaconda/packaging.log > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/N566CST3DAXIL… > _______________________________________________ > Users mailing list -- users(a)ovirt.org > To unsubscribe send an email to users-leave(a)ovirt.org > Privacy Statement: https://www.ovirt.org/privacy-policy.html > oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ > List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/JCAQU32UZSEWK…

Q: Error ID 119 - ioctl(KVM_CREATE_VM) failed: Cannot allocate memory
by Andrei Verovski 22 Jun '22

22 Jun '22

Hi ! Does this error message means node runs out of RAM? Quite strange since there are about 20 GB of free RAN, and VM requires only 8. I noticed this happen till Vinchin was in a process of removing snapshot from another VM. Thanks. VM Jumis_VM-Active is down with error. Exit message: internal error: process exited while connecting to monitor: ioctl(KVM_CREATE_VM) failed: 12 Cannot allocate memory 2022-06-22T19:50:46.501704Z qemu-kvm: failed to initialize KVM: Cannot allocate memory.

Move Master Storage Domain
by john＠penrod.net 22 Jun '22

22 Jun '22

Running oVirt 4.3.10. Three storage domains. #1 is the current master. No disks/data remain on it. All virtual machines have been moved. I plan to put it in maintenance mode and let it force an election. I don't care which of the remaining two become master. Will this impact virtual machines that are currently running? If possible, I need to keep them running. Thoughts?

Cannot export VM to another data domain. "o.original_template is undefined"
by Gilboa Davara 22 Jun '22

22 Jun '22

Hello, 4.4.10 Gluster based cluster w/ 3 nodes. I'm backing up all VMs before upgrading the setup to 4.5. (Hopefully done right before 4.5.1 w/ Gluster fix is released). When trying to export a VM to another data domain, several VMs show the following error: "Export VM Failed. o.original_template is undefined". Engine log looks clean (I see nothing about the failed upgrade). Any idea what's broken? - Gilboa

21 Jun '22

Hi, i convertet my ovirt 4.5 tu ovirt 4.5 hyperconverged. (activate on cluster the gluster service and reinstalled all hosts) I can create bricks on hosts and i'm able to create a Volume. All with the Ovirt GUI. But if i want to activate the Volume, i get the error mesage that no host with running gluster is found in my cluster. All hosts show message that ovirt think glusterd ist not running, but its running on all hosts. What can i du to use gluster with the lokal storage on each host? Greatings Michael

Ovirt 4.4 - starting just-installed host from ovirt console fails
by David Johnson 21 Jun '22

21 Jun '22

Good afternoon all, I recently had to rebuild my cluster due to a self inflicted error. I have finally managed to get the ovirt host software installed and communicating on all hosts. The first host installed and started cleanly. However, after installation the second host is failing to start. Prior to my cluster crash, this host was running well in the cluster. During the downtime, we applied microcode and BIOS updates as part of the recovery process. I have reviewed this chain: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/N3PPT34GBRLPLT… and reached a dead end. Based on what I see (in the long stream of logs and info following), it looks like I should change the cluster CPU type from Cascadelake to Haswell to restore normal operation. The long involved stuff: The Engine reports: [image: image.png] Host CPU type is not compatible with Cluster Properties. [image: image.png] The host CPU does not match the Cluster CPU Type and is running in a degraded mode. It is missing the following CPU flags: model_Cascadelake-Server-noTSX. Please update the host CPU microcode or change the Cluster CPU Type.

Preferred RHEL Based Distro For oVirt
by Clint Boggio 21 Jun '22

21 Jun '22

Good Day All; i am inquiring about which RHEL based distros are currently preferred and which ones are currently supported. I know the oVirt project is a RH entity and so RHEL and CentOS-Stream are the base offering. Would it, or is it, feasible for Rocky 8.X, or Alma 8.X to be the base OS for an oVirt deployment seeing as though they both RHEL clones ? How confident is the user community in the stability of CentOS-Stream in terms of production use as compared to Alma or Rocky ?

failed to mount hosted engine gluster storage - how to debug?
by diego.ercolani＠ssis.sm 21 Jun '22

21 Jun '22

Hello, I have an issue probably related to my particular implementation but I think some controls are missing Here is the story. I have a cluster of two nodes 4.4.10.3 with an upgraded kernel as the cpu (Ryzen 5) suffer from an incompatibility issue with the kernel provided by 4.4.10.x series. On each node there are three glusterfs "partitions" in replica mode, one for the hosted_engine, the other two are for user usage. The third node was an old i3 workstation only used to provide the arbiter partition to the glusterfs cluster. I installed a new server (ryzen processor) with 4.5.0 and successfully installed glusterfs 10.1 and inserted the arbiter bricks implemented on glusterfs 10.1 while the replica bricks are 8.6 after removing the old i3 provided bricks. I successfully imported the new node in the ovirt engine (after updating the engine to 4.5) The problem is that the ovirt-ha-broker doesn't start complaining that is not possible to connect the storage. (I suppose the hosted_engine storage) so I did some digs that I'm going to show here: #### 1. The node seem to be correctly configured: [root@ovirt-node3 devices]# vdsm-tool validate-config SUCCESS: ssl configured to true. No conflicts [root@ovirt-node3 devices]# vdsm-tool configure Checking configuration status... libvirt is already configured for vdsm SUCCESS: ssl configured to true.

Done configuring modules to VDSM. [root@ovirt-node3 devices]# vdsm-tool validate-config SUCCESS: ssl configured to true.

Virtual disk shareable checkbox is greyed out when using GlusterFS storage domains
by Ken Holmes 21 Jun '22

21 Jun '22

Is there a work around that will allow multiple VM's to share a disk with out using the network? I read Dave White's Thread but saw no resolution except maybe using NetApp. Thanks
