[Lustre-discuss] mds backup question

[Jason Brooks]

Hello,

Now that the getfattr operation is done, here are the specs:

the mds filesystem (mounted as type ldiskfs) has 7.7 gigabytes in use.

however, the getfattr operation produced an ascii file that is 20 gigabytes in size.

is this reasonable?

Hello,

I am running a file-level backup of an 1.8 mds system.  At the moment, I am running the getfattr command as mentioned on page 15-3 in the lustre fs manual.  The biggest thing i a noticing, is that the attributes are as large or larger than the actual filesystem.  I expect that when converting bits to ascii data, the amount of space used will increase.  The question though is "how much"?  It doesn't seem reasonable for the bits to inflate THAT much.
