Hi! Those seem to be Postgres database files. You'll either destroy the database or cause serious damage to it if you remove them. If you wan't those cleared you should identify tables that can be trimmed and then vacuum the database. At first I would try to do a full vacuum of the databases. This might free some disk space. There should be an engine-vacuum and a dwh-vacuum commands which do this. -Juhani On Fri, May 7, 2021 at 2:53 PM Pascal D <pascal(a)butterflyit.com&gt; wrote: > > I have an issue with my 4.3 hosted-engine.

Finding out what table is behind those files is harder. But if you want to know this should work: https://www.2ndquadrant.com/en/blog/postgresql-filename-to-table/. -Juhani On Fri, May 7, 2021 at 3:35 PM Pascal D <pascal(a)butterflyit.com&gt; wrote: > > Thank you.

is it safe to systemctl stop ovirt-engine-dwhd on a running hosted-engine will running subsequently dwh-vacuum reclaim any space without adding any while doing it?

Appliance hosted-engine on block storage (fc,iscsi). Have you checked that you are not wasting space on the disk itself? When I setup my hosted-engine, I created a 100GB lun, and told the setup routine to make a 85GB disk, which it did, however the appliance only used 30GB of that, leaving 55GB unused. Using basic disk tools, you can add that space to the root file-system. Use 'fdisk' to create another partition from the unused space, and tag it for Linux LVM. Use 'pvcreate' to mark it for LVM. Use 'vgextend' to add it to the volume group that hold the root file-system. Use 'lvextend' to extend the root file-system to the gained volume-group space. -----Original Message----- From: Pascal D <pascal(a)butterflyit.com&gt; Sent: Friday, May 7, 2021 6:52 AM To: users(a)ovirt.org Subject: [ovirt-users] hosted-engine /var full I have an issue with my 4.3 hosted-engine.
