The BEST command to achieve the task of moving the fileshare from serverA to /newshare located on serverB with all permissions and attributes preserved is option A, which is rsync -aHAX /share/* serverB:/newshare.
Here's a detailed explanation of the command and why it is the best option:
rsync: Rsync is a popular utility for syncing files between systems. It is commonly used for making backups, distributing files, and mirroring websites, as well as other tasks.
-a: The -a option stands for "archive," and it is used to preserve the original file permissions, ownership, timestamps, and other attributes.
-H: The -H option tells rsync to preserve hard links, which are links between files that share the same inode. This is important for maintaining file integrity, as hard links can be used to prevent data loss in case one file is deleted or corrupted.
-A: The -A option is used to preserve ACLs (Access Control Lists) and extended attributes, which are used to assign permissions and other metadata to files and directories.
-X: The -X option is used to preserve extended attributes, which are used to assign additional metadata to files and directories.
/share/*: This specifies the source directory that needs to be copied. In this case, it is /share and the * wildcard tells rsync to copy all the files and subdirectories within the /share directory.
serverB:/newshare: This specifies the destination directory where the files and directories will be copied. In this case, it is /newshare directory located on serverB.
Therefore, the command rsync -aHAX /share/* serverB:/newshare will copy all the files and directories from /share on serverA to /newshare on serverB, while preserving their original permissions, ownership, timestamps, and other attributes, including hard links, ACLs, and extended attributes.
Option B, dd if=/share/* of=serverB:/newshare is not a suitable command as dd is used to copy and convert data. It cannot be used to copy directories or preserve attributes and permissions of files.
Option C, tar -cvf /share/* serverB:/newshare is not a good choice as well, because tar command will only archive the files and directories. It will not preserve the attributes and permissions of files. To preserve the attributes, you will need to include additional options like -p or --preserve-permissions, -a or --preserve=all, -o or --no-same-owner, -g or --no-same-group, -S or --sparse, and so on. But even then, tar may not be the best tool to use for copying files across servers.
Option D, mirrorlv /share/* serverB:/newshare is not a valid Linux command.
