    X server not running after migrating from ESXi to Proxmox on CentOS 7 VMs

    Thank you bbgeek. I will go through the link and give it a try. I created a brand new VM in PVE and installed CentOS 7.9 on it. The X11 forwarding works. So it has to do with the new virtual hardware like you mentioned new NIC designation , change in drivers, or something similar. I did try...

    X server not running after migrating from ESXi to Proxmox on CentOS 7 VMs

    Hello, We were a VMWare shop for over 15 years. Recently I migrated most of our VMs from ESXi into Proxmox 7.2 (new to proxmox). Initially we had server random crash issue. It was fixed by identifying a couple of failed ram modules. The two clustered Proxmox servers have been up and stable for...

    Missing VM disk images after PVE reinstall

    Find out the filesystem type: file -s /dev/group1/vm-101-disk-0 or if it's symlinked, then file -L -s /dev/group1/vm-101-disk-0 Then mount it with 'mount -t the-filesystem-type /dev/group1/vm-101-disk-0 /mnt/fedora' --where the-filesystem-type is from the file type the 'file' command output...

    Missing VM disk images after PVE reinstall

    Run 'lvdisplay', it'll give you details including LV Path. You can then mount it to your local filesystem (e.g. /mnt/) with the correct filesystem type.

    Server crash

    I had a 7.2 server that crashed randomly, sometimes several times a day. I enabled kernel dump and finally caught the error: one of the memory modules was bad. Replaced the module with a new one and the server has been up for 41 days now without a crash. Not sure if it's your case but it might...

    Disk smart status no longer working

    The code below works for my Dell Perc H730_mini RAID for /dev/sda (same as yours): We only have /dev/sda-sdc so I changed char_index to a-c and changed device to megaraid. The S.M.A.R.T. value now shows 'OK'. Hope it works on your server. #!/bin/bash SMARTCTL=/usr/sbin/smartctl.orig...

    [SOLVED] Proxmox 7.1-4- migration aborted: no such logical volume pve/data

    I ran into the same problem. In my case, it's a lvmthin I created called hd8thin. Commented it out of the /etc/pve/storage.cfg and was able to migrate VMs back to the node. #lvmthin: hd8thin # thinpool hd8thin # vgname hd8t # content images,rootdir # lvs LV VG Attr...
