Sometimes you want to quickly identify configuration differences between two hosts.

These could be different settings in configuration files, files that are present on one host but missing on the other, or any number of other differences. The following script helps you detect differences in files and directories between two hosts. Of course, the more files it has to process, the longer it will take.

#!/bin/bash

# Parameter prüfen
if [ "$#" -ne 5 ]; then
    echo "Usage: $0 <DATEI|VERZEICHNIS> <REMOTE_HOST1> <REMOTE_USER1> <REMOTE_HOST2> <REMOTE_USER2>"
    exit 1
fi

PFAD="$1"
REMOTE_HOST1="$2"
REMOTE_USER1="$3"
REMOTE_HOST2="$4"
REMOTE_USER2="$5"

# Teste SSH-Verbindung zu beiden Hosts
for HOST_USER in "$REMOTE_USER1@$REMOTE_HOST1" "$REMOTE_USER2@$REMOTE_HOST2"; do
    echo "[INFO] Testing SSH connection to $HOST_USER..."
    if ! ssh -o BatchMode=yes -o ConnectTimeout=5 "$HOST_USER" true 2>/dev/null; then
        echo "[ERROR] SSH connection to $HOST_USER failed!"
        exit 1
    fi
    echo "[INFO] SSH connection to $HOST_USER successful."
done

# Vergleichsfunktion für einzelne Dateien
vergleiche_datei() {
    remote_datei="$1"

    TMP_REMOTE1=$(mktemp)
    TMP_REMOTE2=$(mktemp)
    TMP_DIFF=$(mktemp)

    # Hole und normiere Datei von Host1
    if ! ssh "$REMOTE_USER1@$REMOTE_HOST1" test -f "$remote_datei"; then
        echo "[MISSING] '$remote_datei' missing on $REMOTE_HOST1"
        rm -f "$TMP_REMOTE1" "$TMP_REMOTE2" "$TMP_DIFF"
        return
    fi
    ssh "$REMOTE_USER1@$REMOTE_HOST1" "grep -v '^\s*#' '$remote_datei' | grep -v '^\s*\$' | sed 's/^\s*//;s/\s*\$//' | sort" > "$TMP_REMOTE1"

    # Hole und normiere Datei von Host2
    if ! ssh "$REMOTE_USER2@$REMOTE_HOST2" test -f "$remote_datei"; then
        echo "[MISSING] '$remote_datei' missing on $REMOTE_HOST2"
        rm -f "$TMP_REMOTE1" "$TMP_REMOTE2" "$TMP_DIFF"
        return
    fi
    ssh "$REMOTE_USER2@$REMOTE_HOST2" "grep -v '^\s*#' '$remote_datei' | grep -v '^\s*\$' | sed 's/^\s*//;s/\s*\$//' | sort" > "$TMP_REMOTE2"

    if diff -u "$TMP_REMOTE1" "$TMP_REMOTE2" > "$TMP_DIFF"; then
        echo "[EQUAL] $remote_datei"
    else
        echo "[DIFFERENCE] $remote_datei"
        echo "============== Difference: $remote_datei =============="
        cat "$TMP_DIFF"
        echo "======================================================="
    fi

    rm -f "$TMP_REMOTE1" "$TMP_REMOTE2" "$TMP_DIFF"
}

# Wenn Verzeichnis → rekursiv vergleichen
if ssh "$REMOTE_USER1@$REMOTE_HOST1" test -d "$PFAD"; then
    echo "[INFO] Directory mode: Searching '$PFAD' recursively on $REMOTE_HOST1..."
    mapfile -t dateien < <(ssh "$REMOTE_USER1@$REMOTE_HOST1" "find '$PFAD' -type f")
    for datei in "${dateien[@]}"; do
        vergleiche_datei "$datei"
    done
elif ssh "$REMOTE_USER1@$REMOTE_HOST1" test -f "$PFAD"; then
    vergleiche_datei "$PFAD"
else
    echo "[ERROR] '$PFAD' does not exist as file or directory on $REMOTE_HOST1."
    exit 1
fi

this will show things like:

Sometimes it is necessary to quickly compare the list of installed packages between two hosts in order to identify any differences. Provided you have access via SSH key, you can use the following script from a third machine (or from one of the hosts itself) to compare two systems with each other.

#!/bin/bash

if [ $# -ne 2 ]; then
    echo "Usage: $0 <remote_host1> <remote_host2>"
    exit 1
fi

REMOTE1="$1"
REMOTE2="$2"

TMP1=$(mktemp)
TMP2=$(mktemp)

echo "==> Pakete von $REMOTE1 werden geholt..."
ssh "$REMOTE1" "dpkg-query -W -f='\${Package}\n'" | tr -d '\r' | grep -v '^$' | sort > "$TMP1"
COUNT1=$(wc -l < "$TMP1")
echo "Pakete insgesamt auf $REMOTE1: $COUNT1"

echo "==> Pakete von $REMOTE2 werden geholt..."
ssh "$REMOTE2" "dpkg-query -W -f='\${Package}\n'" | tr -d '\r' | grep -v '^$' | sort > "$TMP2"
COUNT2=$(wc -l < "$TMP2")
echo "Pakete insgesamt auf $REMOTE2: $COUNT2"

echo
echo "Pakete, die NUR auf $REMOTE1 installiert sind:"
comm -23 "$TMP1" "$TMP2"
echo
echo "Pakete, die NUR auf $REMOTE2 installiert sind:"
comm -13 "$TMP1" "$TMP2"

rm -f "$TMP1" "$TMP2"

an output can show:

bash compare-pkgs.sh slave1 slave2

==> Pakete von slave1 werden geholt...

Pakete insgesamt auf slave1: 595

==> Pakete von slave2 werden geholt...

Pakete insgesamt auf slave2: 584

Pakete, die NUR auf slave1 installiert sind:

inetutils-telnet

libblas3

liblinear4

liblua5.3-0

libpcap0.8

libpcre3

libprotobuf-c1

libunwind8

linux-image-6.1.0-28-amd64

lua-lpeg

net-tools

Pakete, die NUR auf slave2 installiert sind:

this help to decide which packets to install on slave2 or remove on slave1 to be equal.

I would like to (hopefully with the team's permission) open a thread where friendly people can share helpful scripts that are not directly related to OMV, but that make life easier—for example, scripts that can be used with the script plugin.

Personally, I find it rather complicated to determine when exactly something was installed in Debian. While there is plenty of information available, evaluating it is complex. Here, therefore, is a Bash script that accomplishes this task.

#!/bin/bash

i'm not 100% shure but...
By normal you actiavte homedirs only in the SMB/CIFS Tab. There is no need to create an extra share for homedirs but
if you do it on your own at /home, you may destroy the system managed default homedirs in /home/%username%.
You may need additionaly activate Homedirs in User/Setup to use Win Homedirs.
this is mostly SAMBA dependend, So take a look @ the Samba Manual and your /etc/samba/smb.conf.

ok boot from a pendrive linux and post:
#cat /proc/mdstat
#blkid
#mdadm --examine /dev/sd[bc] | grep -E "^/dev|Update|State|Event|Role|Array State"

you set up raid on hole disks, not on patitions? weired.

Your problem is a lack of know-how. reformat your drives and use lvm & ext4. zfs is not recommended as votdev told.

What does "omv under Proxmox" mean? OMV as LXD in a Proxmox environment or OMV baremetal with a Proxmox kernel? "Under" is not a technical term. And why RAID? The RAID array starts even without mdadm.conf if at least the corresponding disks / bootsectors are found. Where did the disk or the RAID array with the uuid go? Why didn't the installation create mdadm.conf if it was supposedly initialized correctly? Did you set up the RAID in omv, or is it part of your Proxmox server? Did you install the md plugin? Did you reboot after installation and check if it was still running? Are there any differences in the configuration since then? Questions, questions, and more

you can boot via pxe to see lan lights, there is no need to reinstall os'es for hardwarediagnostics. Or use a pendrive Linux and take a look at dmesg.

It's not uncommon for multiple disks to fail one after the other in a RAID. They were usually purchased at the same time from the same batch and are subjected to the same load in the RAID. So why shouldn't they fail sooner? With six drives, you usually use a spare drive. And you usually have at least one spare disk in stock. RAID 5 doesn't mean it will last forever. It mean, it is easy to maintain without downtime - if you care right.
And by the way, 54° are much too warm for a Harddisk and constantly maybe a reason for dying drives.

omv depends on os's and os's depend on drivers and drivers depend on bios and bios depends on hardware.
if you get no lights at the active lan port then omv it is the wrong (most distant) place to look for Problems.
look at your bios or in os (driver) logs... i 'm shure, your hardware lan port is gone. maybe a thunderstrike nearby.

thank you

Oh, I didn’t mean to suggest using RAID with USB drives — I was just comparing a fast single USB drive on a USB 3.2 port to a RAID setup in a NAS.

Of course, you shouldn’t build a RAID using USB drives...

And yes, not all RAID levels detect or correct bit rot —

but honestly, if a RAID setup can’t even detect bit rot, it’s not really worth using anyway.

RAID and NAS were great solutions back when cloud storage didn’t exist and SATA/NVMe weren’t around.

Today, many users don’t need that complexity. A fast USB 3.2 NVMe drive (e.g. 2–4 TB) can deliver 4–10 GB/s — faster than any LAN — and is more than enough for typical use cases.

USB ≠ slow anymore. USB 3.2 outperforms SATA, and modern drives have better error correction.

So no, “never use USB drives” is outdated advice.

Why still use RAID then? Not for speed — but for reliability. Bit errors still happen, and RAID helps reduce that risk.

Do you care if one bit flips in a movie? Probably not.

Do you care if it flips in a production system or codebase? Definitely.

Bottom line: RAID doesn’t replace backups. But if your data must be reliable, use it.

If not — keep it simple.

installing or upgrading?
why you don't use actual versions?
Installing : Maybe someone was faster then you changing the default passwords
upgrading : Maybe something other went wrong ...

but without more info... we can't help.
try to get your Server back if you sit in front of... init=/bin/bash is the trick.

That's okay — I just wanted to show that everyone should always be careful about what to click on.

This issue affects many people: fake shops, fake websites, fake identities, and so on.

I think it's great that you're also checking the links.

In my opinion, this isn’t a small Spanish computer company, but rather someone trying to distribute trojans worldwide.

His IP address points to an HAProxy server located in Lansing, USA — which also hosts domains like gemoney.com.

That domain, in turn, appears in blocklists such as EasyList due to trojan-related activity involving the URL pattern "page_bouncy_php?$doc_ument".*

If there’s a virtual name host setup behind it, he might just be unlucky that the same server hosts other questionable services.

But if he owns the entire server, then this is clearly a fake front.*some chars modifyed

on his domain AND gemoney.com this happen actualy.
