Dear All, When backing up the MDT of the lustre filesystem, I saw that one can use "tar" with option --sparse to avoid mistakenly archiving data with full of zeros. My question is that, Is there any requirement of the "tar" version for this function ? For example, I saw GNU tar version 1.20 also supports --sparse option. Could I use it to backup MDT in the ldiskfs method ?
I don't care about the support of copying extended file attributes in tar (e.g., -xattrs), since I can use getfattr and setfattr to do this task. Thank you for your kindly help.
