Vmdk Corrupted //free\\ [DIRECT]

I pull the manifest. The VMDK is 2TB thin-provisioned. The VM won't boot. The backup ran six hours ago, but the differential is useless because the block map is scrambled.

if [ ! -z "$FLAT_SIZE" ]; then CALC_MB=$(($FLAT_SIZE / 1024 / 1024)) echo "Health: $vmdk is $CALC_MB MB nominal." >> $LOG_FILE fi done VMDK corruption is rarely a hardware failure. It is a timing failure —where the hypervisor assumes a write completed before the storage array confirms it. The fix involves bypassing the broken descriptor and forcing a rebuild from the raw extent. Always keep a backup of the .vmdk descriptor file separately from the flat file. vmdk corrupted

I open the server01.vmdk (descriptor file) in a terminal. The backup ran six hours ago, but the

[SUCCESS] Grain table rebuilt. 1,892,471 sectors recovered. [WARNING] 204 sectors unrecoverable (log files, temporary data). The SQL database performs a recovery on mount. I lose 15 minutes of transaction log data. The business accepts the loss. To prevent this, implement a VMDK health check cron job on the ESXi host:

The CID (Content ID) was reset to fffffffe — a flag meaning "unknown or corrupted parent." The flat extent is intact, but the mapping is blind.
