Fixup Operation Fails in HCX-OSAM Due to Unsupported FAT32 File System Type

Products

• VMware HCX

Issue/Introduction

• HCX OS Assisted Migration (OSAM) fails during the fixup phase for a Linux Virtual Machine.
• You can see error stating "Failed to perform fix-up operation on migrated VM. Failed to finish fixup cleanup" under Services > Migration.

• Logs similar to the below may be seen in Target HCX Manager fixup logs /common/logs/admin/<migration-id>_fixup.log


  <timestamps> INFO log.py::info():65 SyncFilesystem(####-C54D @ /dev/sda1): restoring attributes
  <timestamps> WARNING log.py::warning():79 SyncFilesystem(####-C54D @ /dev/sda1): skipping because it is of type fat32

  


• Operation failed entries seen in Source HCX Manager /common/logs/admin/app.log :

  <timestamps> UTC [FailureDetectionService_EventListener, , , TxId: ] INFO  c.v.v.h.f.FailedJobEventsListener- Skipping the jobType OsAssistedMigrationJobs and workflow Type Linux Fixup from notifying.

  {"fsName":"/boot/efi","fsSize":2093040,"fsType":"FAT32",

 

• Checking the source linux Guest OS details confirm the partition to be FAT32 which is unsupported : lsblk -f
  
  

 

Environment

VMware HCX

Cause

The migration fails because the source Guest OS utilizes an unsupported FAT32 file system partition (such as /boot/efi). VMware HCX OS Assisted Migration (OSAM) does not support the FAT32 file system format for Linux fixup workflows.

Resolution

Attempt the OSAM migration with the Guest OS having only supported file systems: ext2, ext3, ext4, XFS .
