Filesystem Recovery Course - VMFS Recovery Test

What is the size of segments on VMFS filesystem?

512 KB
512 MB
256 KB
256 MB

How are large clusters numbered?

arbitrarily
sequentially from the beginning of the volume

What is common between VMFS and EXT?

both filesystems use a dedicated repository for small files
both filesystems use two different cluster sizes
both filesystems use inodes

VMFS stands for

virtual machine file system
volume manager file system
virtual machine file storage
virtual machine file structure

Check what inode payload can store

up to 256 indirect block pointers
file content for files less than 1 KB
up to 256 pointers to small clusters
128 pointers to small clusters and 128 indirect block pointers
128 pointers to large clusters and 128 pointers to small clusters
up to 256 pointers to large clusters

Where is small file repository stored on a VMFS volume?

in the end of the volume
one copy in the beginning and other – in the end
in the beginning of the volume

What is the typical size of large cluster?

1 MB
32 KB
4 MB
512 KB

Where does VMFS store files smaller than 1 KB?

inside the corresponding inodes
in indirect blocks table
in a dedicated repository

VMFS uses only contiguous areas on a disk to store files

false, files can be fragmented
true, files cannot be fragmented

Can VMFS combine several physical disks?

no
yes, but only into JBOD
yes, but only into JBOD and mirror

We have a mailing list in which we talk about interesting cases we encounter and share some tips and tricks.
