ReclaiMe Data Recovery Training
Filesystem Recovery Course - VMFS Recovery Test
What is the recommended data recovery approach for a multi-disk VMFS volume?
do RAID0 recovery first and then do filesystem recovery
first reassemble the volume from extents and then do filesystem recovery
do filesystem recovery on each disk separately
What happens when a file is deleted?
metadata in the corresponding inode is overwritten with zeros
payload in the corresponding inode is overwritten with zeros
an entire inode is overwritten with zeros
Carving doesn’t work well on a VMFS volume
VMFS uses only contiguous areas on a disk to store files
false, files can be fragmented
true, files cannot be fragmented
What parts are there in an inode?
metadata, parent pointers, and payload
metadata, segment numbers, and payload
metadata and payload
Where are the numbers of the first and the last segments stored?
in the extent header
in the volume header
When was the first release of VMFS filesystem?
What is the typical size of small cluster?
What is the size of VMFS inode?
Check what inode payload can store
file content for files less than 1 KB
128 pointers to small clusters and 128 indirect block pointers
128 pointers to large clusters and 128 pointers to small clusters
up to 256 indirect block pointers
up to 256 pointers to large clusters
up to 256 pointers to small clusters
