After updating a graylog we get an errors like:

Unable to retrieve version from Elasticsearch node: Hostname datanode not verified 
Host name 'datanode' does not match the certificate subject provided

This can be fixed disabling ssl/tls betwen containers

put into .env this string:

then restart containers

docker compose stop
docker compose up -d

Apply Cloud-init to VM

qm set 9000  --cicustom "user=local:snippets/9000.yaml"

Now we have imported cloud image and can prepare it. At this stage you can customize somehow your image

qm start 9000 && qm terminal 9000
sudo -i
cat /dev/null > /etc/machine-id
cloud-init clean
history -c
shutdown -h now

Convert our VM to template

qm template 9000

And now we can create a VM from template:

qm clone 9000 107 --full --name mgmt

ProxMox migration fails: Host key verification failed.

Запись создана 22 марта, 2024

If you get an error, on migrating VM from one ProxMox to another, like this:

# /usr/bin/ssh -e none -o 'BatchMode=yes' -o 'HostKeyAlias=pve-n23' root@10.10.10.10 /bin/true
Host key verification failed.
ERROR: migration aborted (duration 00:00:01): Can't connect to destination address using public key
TASK ERROR: migration aborted

And you have FreeIPA installed on proxmoxes, you can fix it (temporary) by

 ssh -o 'HostKeyAlias=pve-n23' root@10.10.10.10 /bin/true

or permanently, by commenting string

 #GlobalKnownHostsFile /var/lib/sss/pubconf/known_hosts

in /etc/ssh/ssh_config.d/04-ipa.conf

LVM resize HOWTO

Запись создана 15 марта, 2024

We have an virtual machine with 165Gb disk, and added extra 10Gb. Now we need to extend filesystem inside a VM

lets check trat extra 10Gb is available in VM

# fdisk -l /dev/sdb
Disk /dev/sdb: 175.2 GiB, 187924742144 bytes, 367040512 sectors

Checkout the physical volume size, it’s 165Gbyte

# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sdb
  VG Name               data
  PV Size               <165.02 GiB / not usable 2.00 MiB

let’s resize it

# pvresize /dev/sdb
  Physical volume "/dev/sdb" changed
  1 physical volume(s) resized or updated / 0 physical volume(s) not resized

and check again. ok we see that it extended

# pvdisplay
  --- Physical volume ---
  PV Name               /dev/sdb
  VG Name               data
  PV Size               <175.02 GiB / not usable 2.00 MiB

logical volume is extended to, and have Free Size 10GiB

# vgdisplay
  --- Volume group ---
  VG Name               data
  VG Size               <175.02 GiB
  Alloc PE / Size       42244 / <165.02 GiB
  Free  PE / Size       2560 / 10.00 GiB

now we need to extend logical volume

# lvextend -l +100%FREE /dev/mapper/data-storage
  Size of logical volume data/storage changed from <165.02 GiB (42244 extents) to <175.02 GiB (44804 extents).
  Logical volume data/storage successfully resized.

and resize a file system (in my case it’s xfs)

# xfs_growfs /dev/mapper/data-storage

And now we see that filesystem is growed

# df -h /opt/docker/
Filesystem                Size  Used Avail Use% Mounted on
/dev/mapper/data-storage  175G  147G   29G  84% /opt/docker

Sangoma Linux after migration from VMWare ESXi to ProxmoxVE fails to boot

Запись создана 13 марта, 2024

After migration Sangoma Linux (FreePBX on CentOS7) from vmware to proxmox

qm importovf 7804 PBX002.ovf local-zfs

OS fails to boot with error:

Could not boot
/dev/SangomaVG/root does not exist
/dev/SangomaVG/swaplv1 does not exist
/dev/mapper/SangomaVG-root does not exist

What do we need?
1. add network adapter, chose model «VMware vmxnet3» and set previously used MAC-address
2. detach hard disk and attach it as sata
3. boot the VM from CentOS-7-minimal.iso and

mount --bind /run /mnt/sysimage/run
 
systemctl start multipathd.service
 
chroot /mnt/sysimage
 
dracut --regenerate-all --force

HP Proliant Gen9 G9 DMAR error

Запись создана 23 ноября, 2023

If you getting an error like this in dmesg on your linux and the physical server is a kind of HP Proliant G9 (Gen9)

 
DMAR: [DMA Write NO_PASID] Request device [04:00.0] fault addr 0x791f4000 [fault reason 0x05] PTE Write access is not set
DMAR: DRHD: handling fault status reg 402

You can just ignore it :)

OR if can reboot yourt server, there are several ways to «fix» it

pass a «intel_iommu=on» option to kernel or enter RBSU (BIOS) pressing F9 on startup screen
System configuration >> chose embeded LOM >> Device configuration menu >> SRV-IOV >> set Disabled

Same thing on HPE Proliant Gen10 is called «HP Shared Memory Features»

Mikrotik FAN speed on CCR2004-1G-12S+2XS

Запись создана 13 ноября, 2023

By default settings system health on mikrotik CCR2004 shows 0 RPM fan speed.

In my case the temperature of CPU was about to 60C but there is no direct settings to set FAN speed, so i set the temp to run fullspeed this way

/system health settings set fan-full-speed-temp=45C fan-target-temp=45C
