Track 1: Hoʻopakele iā VMware ESXi & Workstation .vmdk nā kaulahao paʻi kiʻi¶

I loko o VMware ESXi, aia i loko o kahi disk virtual he ʻelua faila kaʻawale no ka disk base a me ʻelua faila kaʻawale no kēlā me kēia kiʻi paʻi: 1. He faila wehewehe kikokikona liʻiliʻi (-500-byte) (Server.vmdk a Server-000001.vmdk) e paa ana i ka CID, parentCID, geometry disk, a me ka inoa file pololei o ka nui binary. (E hoʻomaopopo: Hūnā ka waihona ESXi Datastore Browser pūnaewele GUI i ka paʻa -flat.vmdk a -sesparse.vmdk nā waihona binary a hōʻike wale i hoʻokahi ikona i hui ʻia, pono ʻoe e hoʻohana i kahi SSH terminal session ma ka ESXi host e ʻike i nā faila ʻoiaʻiʻo). 2. He File Extent Data Nui-gigabyte binary (Server-flat.vmdk no ka diski kumu, a Server-000001-sesparse.vmdk a i ʻole Server-000001-delta.vmdk no kēlā me kēia paʻi kiʻi).

Nānā 1A: Hoʻoponopono "The parent virtual disk has been modified since the child was created (Parent CID mismatch)"¶

1. SSH i loko o ka ESXi host a hoʻokele i ka papa kuhikuhi hale kūʻai ʻikepili o VM:

   cd /vmfs/volumes/<Datastore_Name>/<VM_Folder_Name>/
   ls -la *.vmdk
   

2. Pa'i i ka CID, parentCID, a parentFileNameHint ma nā mea wehewehe kikokikona a pau .vmdk faila i ka manawa hoʻokahi: (mea nui: holo wale cat a i ʻole grep ma ka mea wehewehe kikokikona 500-byte .vmdk faila, ʻAʻole ma ka multi-gigabyte -flat.vmdk a i ʻole -sesparse.vmdk waihona).

   grep -E "CID|parentFileNameHint|Extent description" -A 2 Server.vmdk Server-00000*.vmdk
   

3. ** Hoʻohālikelike i ka CID o kela me keia makua kue i ka parentCID o kana keiki ponoi:** E nānā i ka hopena:

   Server.vmdk:           CID=1a2b3c4d
                          parentCID=ffffffff   (ffffffff means this is the root Base Disk)
   
   Server-000001.vmdk:    CID=99887766
                          parentCID=55443322   <-- ERROR: Should equal Server.vmdk's CID (1a2b3c4d)
                          parentFileNameHint="Server.vmdk"
   
   Server-000002.vmdk:    CID=aabbccdd
                          parentCID=99887766   <-- OK: Matches Server-000001.vmdk's CID (99887766)

4. ** Hoʻoponopono i ka haki parentCID i ka wehewehe keiki a hōʻoia me vmkfstools -e:**
5. ʻO ka mea mua, e hoʻihoʻi i nā faila wehewehe kikokikona (cp Server-000001.vmdk Server-000001.vmdk.bak).
6. Wehe Server-000001.vmdk i loko vi a hoololi parentCID=55443322 i parentCID=1a2b3c4d (kulike Server.vmdk'o kēia manawa CID).
7. E hoʻāʻo i ka pololei o ke kaulahao mai ka paʻi kiʻi hou loa (helu helu kiʻekiʻe) me ka hoʻohana ʻana vmkfstools -e:

   vmkfstools -e Server-000002.vmdk
   

8. Inā paʻa ke kaulahao, hoʻopuka ʻo ESXi: Disk chain is consistent.
9. Hoʻohui ʻAʻole Hoʻopōʻino (vmkfstools -i Klone ma waho o kahi):
10. Ina Server.vmdk ua hoʻololi iki ʻia ma mua o kou hoʻoponopono ʻana i ka parentCID, mai hoʻohui i kahi ma luna o kāu kope hoʻokahi. Akā, kuhikuhi vmkfstools -i ma ka ** kiʻi lau hou loa (Server-000002.vmdk)** a hoʻopaʻa i ke kaulahao holoʻokoʻa i loko o kahi VMDK palahalaha hoʻokahi hou ma kahi hale kūʻai ʻikepili me kahi kaʻawale:

    vmkfstools -i Server-000002.vmdk /vmfs/volumes/<Target_Datastore>/Server_Rescue/Server_Merged.vmdk -d thin
    

11. vmkfstools -i heluhelu i kēlā me kēia poloka mai Server-000002.vmdk iho i lalo Server-000001.vmdk a Server-flat.vmdk ma ka **Read-Whenly Mode ** a kākau i kahi maʻemaʻe, kiʻi ʻole Server_Merged.vmdk me ka hoʻopā ʻole i kāu mau faila kumu.

Hōʻike 1B: Hana hou i kahi 500-byte i nalo a holoi ʻia .vmdk mea wehewehe kikokikona i ka wa Server-flat.vmdk paʻa mau¶

I kekahi manawa hoʻopau ka luna hoʻomalu a i ʻole ka palapala haki Server.vmdk (a i ʻole e pōʻino i 0 bytes), e ho'ōki i ka hōʻike ʻana i ka Pūnaewele Pūnaewele, ʻoiai ʻo ka 500-gigabyte nui Server-flat.vmdk waihona i loaʻa ka 100 pakeneka o kāu ʻikepili maoli e noho mau ana ma laila ma SSH (ls -la *-flat.vmdk).

Hiki iā ʻoe ke hana hou i ka kikokikona maʻamau i nalowale Server.vmdk descriptor file ma 60 kekona me ka nalowale ʻole o hoʻokahi byte o ka ʻikepili i loko Server-flat.vmdk:

# 1. Check the exact byte size of your existing Server-flat.vmdk:
ls -l Server-flat.vmdk
# Example output: -rw------- 1 root root 107374182400 Oct 31 12:00 Server-flat.vmdk  (Exactly 107,374,182,400 bytes)

# 2. Create a temporary dummy VMDK of that EXACT byte size in /tmp or the datastore:
vmkfstools -c 107374182400 -d thin temp_dummy.vmdk

# 3. Delete the dummy binary file (temp_dummy-flat.vmdk) and rename the 500-byte descriptor to Server.vmdk:
rm -f temp_dummy-flat.vmdk
mv temp_dummy.vmdk Server.vmdk

# 4. Edit Server.vmdk in 'vi' and change the filename inside quotes from "temp_dummy-flat.vmdk" to "Server-flat.vmdk":
sed -i 's/temp_dummy-flat.vmdk/Server-flat.vmdk/g' Server.vmdk
# (Also delete the line 'ddb.thinProvisioned = "1"' if the original disk was thick-provisioned)

Nānā 1C: Wehe a .vmdk laka ʻia e kahi mea hoʻokipa ESXi i hoʻopaʻa ʻia a i ʻole ka mea hoʻopio kākoʻo i hāʻule (Cannot open the disk: Failed to lock the file)¶

Inā hōʻole ka VM i ka mana me Failed to lock the file a i ʻole Cannot open disk: Resource busy, kekahi mea hoʻokipa ESXi i loko o ka pūʻulu (a i ʻole kahi mea Veeam/backup HotAdd i hāʻule i ka wā hoʻihoʻi) e paʻa mau ana i kahi laka faila SCSI / VMFS ma. -flat.vmdk a i ʻole -sesparse.vmdk: 1. E nānā inā loaʻa i kahi VM mea hoʻohana i hoʻokuʻu ʻia i kāu hana VM .vmdk i hoʻopili ʻia i kāna mea hoʻoponopono SCSI virtual: Hoʻoponopono i nā hoʻonohonoho o kāu Veeam/CommVault proxy VMs a wehe i nā disks hana i hoʻopili ʻia (koho "Wehe mai ka Mīkini Virtual," ʻAʻole "Holo i nā faila mai ka hale kūʻai data"). 2. E ʻimi i ka helu MAC host ESXi a me ke kaʻina hana honua e paʻa i ka laka VMFS:

vmfsfilelockinfo -p /vmfs/volumes/<Datastore>/<VM_Folder>/Server-flat.vmdk

Track 2: Hoʻopakele iā Microsoft Hyper-V .vhdx a .avhdx nā kaulahao paʻi kiʻi¶

Ma Microsoft Hyper-V, hana kēlā me kēia wahi mākaʻikaʻi (paʻi kiʻi) i kahi diski paʻakikī virtual like ʻole me ka hoʻonui .avhdx (a i ʻole .avhd ma ka palapala VHD kahiko) i hāʻawi ʻia i kahi inoa faila GUID lōʻihi e like me ProdSQL_A1B2C3D4-E5F6-7890-ABCD-1234567890AB.avhdx.

KaʻAnuʻu Hana 1: Palapala ʻāina i ka chronological pololei .avhdx lāʻau makua-keiki ma PowerShell¶

Ma mua o ka hoʻohui ʻana a i ʻole ka hoʻopili hou ʻana i kekahi mea ma Hyper-V Manager, wehe i kahi Elevated Administrator PowerShell pukaaniani ma ka Hyper-V host, hoʻokele i ka waihona i loaʻa kāu .vhdx a .avhdx faila, a holo i kēia laina hoʻokahi e hōʻike i ke kaulahao makua-keiki mai ka mea hou a i ka mea kahiko:

# Inspect every .vhdx and .avhdx in the directory, sorted by LastWriteTime:
Get-ChildItem -Filter "*.*vhd*" | ForEach-Object {
    Get-VHD -Path $_.FullName -ErrorAction SilentlyContinue |
    Select-Object Path, ParentPath, VhdType, FileSize, Size
} | Format-List

E nana i ka Path a ParentPath nā māla. E hōʻike lākou i ke kauoha kaulahao pololei: - ProdSQL.vhdx -> ParentPath: (blank) (Root Base Disk, Kahiko loa) - ProdSQL_1111.avhdx -> ParentPath: D:\VMs\ProdSQL.vhdx (Keiki 1) - ProdSQL_2222.avhdx -> ParentPath: D:\VMs\ProdSQL_1111.avhdx (Keiki 2) - ProdSQL_3333.avhdx -> ParentPath: D:\VMs\ProdSQL_2222.avhdx (Kōpae Leaf Active Hou loa)

KaʻAnuʻu 2: Hoʻoponopono "The chain of virtual hard disks is broken" a i ʻole "Differencing disk parent ID mismatch" (Set-VHD -IgnoreIdMismatch)¶

Pehea inā hoʻoneʻe kekahi i ka waihona VM mai C:\VMs\ i E:\VMs\, a i ʻole i hoʻopaʻa ʻia ProdSQL.vhdx no 5 kekona, hana ProdSQL_1111.avhdx e hāʻule me: The chain of virtual hard disks is broken. The system cannot locate the parent virtual hard disk for the differencing disk a i ʻole There is a mismatch in the virtual disk identifiers?

E hoʻohana i ka mana Hyper-V PowerShell cmdlet Set-VHD me ka -IgnoreIdMismatch hae (ma hope o ke kākoʻo mua ʻana i nā faila):

# Relink a child .avhdx to its parent .vhdx/.avhdx (adding -IgnoreIdMismatch if the parent timestamp/GUID shifted):
Set-VHD -Path "E:\VMs\ProdSQL_1111.avhdx" -ParentPath "E:\VMs\ProdSQL.vhdx" -IgnoreIdMismatch

KaʻAnuʻu Hana 3: Hoʻohui lima i kahi keiki makua ʻole .avhdx kaulahao mai NEWEST a OLDEST (Merge-VHD)¶

Ke waiho ʻia e kahi mea hoʻihoʻi 15 makua ʻole .avhdx waihona i loko o kāu waihona i ʻike ʻole ʻia i loko o ka lāʻau "Checkpoints" Hyper-V Manager GUI, pono ʻoe e hoʻohui lima iā lākou ma PowerShell oiai ua pio ka VM.

E holo i kēia mau kauoha PowerShell ma kahi ** kope hana ** o ka waihona:

# Step 1: Merge Child 3 (Newest) into Child 2:
Merge-VHD -Path "E:\VMs\ProdSQL_3333.avhdx" -DestinationPath "E:\VMs\ProdSQL_2222.avhdx"

# Step 2: Merge Child 2 into Child 1:
Merge-VHD -Path "E:\VMs\ProdSQL_2222.avhdx" -DestinationPath "E:\VMs\ProdSQL_1111.avhdx"

# Step 3: Merge Child 1 into the Base .vhdx:
Merge-VHD -Path "E:\VMs\ProdSQL_1111.avhdx" -DestinationPath "E:\VMs\ProdSQL.vhdx"

Track 3: Hoʻopakele iā Proxmox VE / QEMU / KVM .qcow2 a me VirtualBox .vdi kaulahao¶

1. Ke nānā ʻana a hoʻoponopono ʻana i nā papa QCOW2 L1/L2 Cluster & Refcount Tables (qemu-img check)¶

# Non-destructively flatten an entire QCOW2, VMDK, or VHDX chain into a single clean image:
qemu-img convert -p -O qcow2 top_snapshot_leaf.qcow2 /mnt/rescue_storage/flattened_clean.qcow2

Track 4: Hoʻopakele i nā faila ma waho o ka hui (E unuhi ana i nā faila inā ʻaʻole hoʻomaka ka VM)¶

He aha inā inā ʻaʻole hiki ke hoʻopaʻa ʻia ka ʻōnaehana lawelawe malihini i loko o ka disk virtual, a i ʻole kahi kiʻi waena o ke kaulahao i hōʻino ʻia a pono ʻoe e huki i nā ʻikepili SQL (.mdf/.ldf), nā faila QuickBooks, /var/lib/mysql, a i ʻole nā palapala ʻoihana i loko o nā minuke 30 e hiki mai ana?

** ʻAʻole pono ʻoe e hoʻopaʻa i ka Mīkini Kūikawā no ka unuhi ʻana i nā faila i loko o kāna kīkī koʻikoʻi.

Hanana 1: E kau i kekahi .vmdk, .vhdx, .qcow2, a i ʻole .vdi ma ke ʻano Heluhelu wale nō ma Linux me ka hoʻohana ʻana libguestfs (guestmount / qemu-nbd)¶

Hoʻokomo libguestfs-tools (sudo apt install libguestfs-tools qemu-utils ma Ubuntu / Debian / Proxmox) a kau i ka ** paʻi kiʻi lau hou loa ** i ka ** Read-Only Mode (--ro)**:

# Option A: Using guestmount (Automatically detects internal guest LVM/partitions and mounts read-only):
sudo mkdir -p /mnt/vm_rescue
sudo guestmount -a /path/to/Newest_Leaf_Snapshot.vmdk -i --ro /mnt/vm_rescue
# (If guest OS partitions fail auto-inspection due to dirty NTFS journal, list partitions with 'virt-filesystems -a disk.vmdk -l'
# and mount the specific partition directly with '-m /dev/sda2 --ro -o norecover')

# Option B: Attaching the virtual disk chain as a Read-Only Network Block Device (/dev/nbd0):
sudo modprobe nbd max_part=16
sudo qemu-nbd --read-only --connect=/dev/nbd0 /path/to/Newest_Leaf_Snapshot.qcow2
sudo partprobe /dev/nbd0
lsblk /dev/nbd0
# Now mount /dev/nbd0p2 read-only (with -o ro,norecover for NTFS or -o ro,noload for ext4):
sudo mount -o ro,norecover /dev/nbd0p2 /mnt/vm_rescue

Ke Kaʻina 2: Hoʻoiho koke i ka heluhelu-wale ma ka hoʻohana ʻana iā Windows 7-Zip a i ʻole Disk Management -> Attach VHD (Read-Only)¶

• ** Ke hoʻohana nei i ka 7-Zip (Ke hana nei ma .vmdk, .vhdx, .vhd, .qcow2, a .vdi):** E kaomi ʻākau i kahi kūʻokoʻa a i hoʻopalahalaha ʻia .vmdk, .vhdx, a i ʻole .qcow2 faila ma Windows a koho iā 7-Zip -> Open Archive. Hoʻopau maoli ʻo 7-Zip i nā papa ʻāpana GPT/MBR a me nā ʻōnaehana faila NTFS/ext4 i loko o nā disks virtual ma 100% mode heluhelu-wale nō, e ʻae iā ʻoe e kauo a hoʻokuʻu pololei i nā waihona malihini ma kāu pākaukau i kekona.
• ** Ke hoʻohana nei i ka Windows Disk Management (No .vhdx / .avhdx):** Wehe diskmgmt.msc -> Action -> Hoʻopili iā VHD -> E nānā i ka lau hou loa .avhdx (a i ʻole .vhdx), E NANA I KA PAHU NO [X] Read-only (CRITICAL: Mai poina e nānā i ka heluhelu wale nō, a i ʻole e hoʻololi ʻo Windows i ke poʻo disk), a kaomi iā OK. Hōʻike koke ʻia kāu mau drive C: a me D: ma Windows File Explorer.

Hanana 3: Hana hou i na kaulahao i poino loa me UFS Explorer Professional Recovery¶

Inā ua hoʻopaʻa ʻia a hoʻololi ʻia kahi disk makua i loko o kahi kaulahao VMDK a i ʻole VHDX, a i ʻole inā ʻoki ʻia kahi ʻāpana o ka hale kūʻai ʻikepili VMFS/NTFS. -sesparse.vmdk a i ʻole .avhdx No laila, hōʻole nā mea hana hypervisor iā ia, ʻo UFS Explorer Professional Recovery (a i ʻole R-Studio Technician) hiki iā ʻoe ke hōʻuluʻulu lima i ka disk base maka a me kēlā me kēia kiʻi delta keiki i loko o kahi ** Virtual Delta Stack ** i loko o ka polokalamu RAM, e kāpae ana i ka hypervisor. CID/GUID nānā ke poʻo e kālai a wehe i nā faila malihini.

Track 5: Hoʻihoʻi i kahi faila hoʻonohonoho VM makua ʻole (.vmx, .xml, a i ʻole <vmid>.conf)¶

I kekahi manawa, ʻo ke kaulahao hard disk virtual ponoʻī (*.vmdk, *.vhdx, a i ʻole *.qcow2) he 100 pakeneka paʻa ma ka waihona waihona, akā ʻo ka faila hoʻonohonoho liʻiliʻi e wehewehe ana i ka hoʻonohonoho lako lako o ka Virtual Machine (.vmx ma VMware ESXi, <GUID>.vmcx / .xml ma Hyper-V, a i ʻole /etc/pve/qemu-server/<vmid>.conf i Proxmox VE) i hewa, holoi ʻia, a i ʻole i hoʻokuʻu ʻia i ka wā o kahi ulia pōpilikia.

Inā ʻoe e hana hou i kahi pūpū VM pani me ka mea hoʻokele mālama mālama virtual hewa a i ʻole ke ʻano firmware, e hāʻule koke ka ʻōnaehana lawelawe malihini ma ka pahu me INACCESSIBLE_BOOT_DEVICE (Windows) a hāʻule paha i kahi dracut / initramfs pūpū pilikia (Linux). E hoʻohālikelike i kēia mau hoʻonohonoho hāmeʻa ʻehā i kāu hoʻonohonoho malihini mua ma mua o ka hoʻopili ʻana i kāu disk virtual i hoʻopakele ʻia:
