Hello , I am new to dm-verity and I am finding it hard to use it. This is my setup. On one VM running Ubuntu-12.04,I have a nfs-share partition. I have virtual disk image files of other vm's in this share. I want to perform the integrity check on these files/nfs-share at block level. My nfs-share partition size is 10GB. >From the documentation,I see the numbers. 4096,4096,52224,1,root_hash and salt. I know the doc says 4096 = datablock 4096 = hashblock 52224 = number of blocks 1 = hash offset SIZE=$(blockdev --getsz /dev/sdb) dmsetup create name -r --table "0 $SIZE verity 1 /dev/sdb /dev/sdc 4096 4096 52224 1 sha256 <root_hash> <salt>" But my question how do I get these values for my setup? How do I know the size of data block /hashblock in my case?How I calculate the number of blocks and root hash and salt to feed into the command. Can you please let me know the process to get these values? Also it mentions to use verity setup command for this purpose. Can you let me k now the arguments or an example here? -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
