I shutdown all VMs, then run "iotops", here is output: also here is average hourly output with disabled VMs (IO Delay reduced..):

Thanks, I saw this post. I do some modifications in sysctl.conf and reboot, but nothing changed:

Good day, Peter/ Here is iotop output:

Good day. 3 month ago average IO Delay increased dramatically, about 10 or 15 times. Nothing radically changed in VMs. Hypervisor hardware also the same. I have 17 VM running: (10 with Windows 7,10, Server 2012) and (7 with Linux Ubuntu 18.04). There are 3 disks also: all VMs on nvme0n1 (m.2...

Good day, I have VM with 120 Gb virtual disk: Guest operating system (ubuntu linux 12.04 Lts) use only 3,4Gb of disk storage. But backup file of VM is 26Gb! (with LZO compression) If I use gzip type compression size of backup file is 17,5Gb How to reduce size of backup file? Why backup file...

Thanks, it helps! () INFO: starting new backup job: vzdump 233 --compress lzo --remove 0 --storage Seagate_2TB --node pve3 --mode snapshot INFO: Starting Backup of VM 233 (qemu) INFO: status = stopped INFO: update VM 233: -lock backup INFO: backup mode: stop INFO: ionice priority: 7 INFO: VM...

Good day. How to change backup speed? (Virtual Environment 5.2-1) Here is backup log: INFO: starting new backup job: vzdump 233 --mode stop --node pve3 --compress gzip --remove 0 --storage Seagate_2TB INFO: Starting Backup of VM 233 (qemu) INFO: status = stopped INFO: update VM 233: -lock...

Good day, Please help, is any defaults bandwidth limits for ethernet network card in PVE 5.2? In old versions of PVE there was option bwlimits in /etc/vzdump.conf. Was it replaced by datacenter.cfg ? https://pve.proxmox.com/pve-docs/datacenter.cfg.5.html

Thanks to all, I fix the problem. My intel ssd is the reason :(. Intel ssd toolbox didn't find any errors, but when I replace SSD with other device PVE stoped hanging-up.

Just update, but the same result. Proxmox hangup. And addition info: during restore operation proxmox hang up. WEB Interface didn't answer (connection error). Also unable to connect to proxmox via ssh. BUT ping to PVE is OK and the guest machine (VM) is still working, and available. I'm in...

Good day. My Proxmox 4.2-2 hangup during work and write in console input/output error. It seems to me that problem with memory or hdd. I've checked several times memory with memtest and my intel ssd under windows with intel ssd toolbox. No errors, no fails. Free space on SSD and reserved SATA...

I think so. Nothing changed.

Good Evening! There is VM 100 : guest os - Windows Server 2008 standard, with 2 HDD (sata and virtio). Boot partition SATA, Data partithion - virtio. Host pve-manager - 3.4.1, kernel 2.6.32-37-pve. There is a yesterday's backup of VM 100. When I restore VM100 from backup first it starts...

Before using this command to shrink a disk image, you must use file system and partitioning tools inside the VM itself to reduce allocated file systems and partition sizes accordingly. Failure to do so will result in data loss. After using this command to grow a disk image, you must use file...

Convert again from raw to qcow2 (with -O option): qemu-img convert -O qcow2 vm-100-disk-1.raw vm-100-disk-1.qcow2 and VM start :) ! But, guest machine under Linux Ubuntu 14.04 didn't start normally: something wrong with file system after converting?

I did following: stop virtual machine: qm stop 100 convert the image from qcow2 to raw: qemu-img convert vm-100-disk-1.qcow2 vm-100-disk-1.raw then shrink the image the 20G are the new total size: qemu-img resize -f raw vm-100-disk-1.raw 20G then convert it back: qemu-img convert...

Good day. Try: # apt-get update # apt-get install libpve-common-perl

Thanks for answer, but I mean different. After this : https://pve.proxmox.com/wiki/Shrink_Qcow2_Disk_Files size of VM backup and time for operations backup/restore decreased. But I want to reduce size of quest VM disk on Storage from 100Gb to 20 Gb.

Good day, everyone. I have VM under PVE 4.1 with 100Gb virtual disk qcow2. Real data usage of guest machine - 10 Gb. I'd like to shrink/decrease size of virtual drive from 100Gb to 20Gb. With Resize Disk command I can only increase virtual drive size. Is any simple way to shrink/decrease virtual...
