[SOLVED] Are XFS disks formatted with the new checksum option?

[alphazo]

Title says it all. I'm considering moving to 6.0 so I can use my preferred backup system "bup" in a more efficient way. Today I cannot run it with a large data set on a 32-bit system today. New filesystem options got my interest too.

 

I'm wondering if formatting a disk under unRAID selecting XFS uses the new self-describing metadata option (aka CRC32)? It should be the "-m crc=1" option for the mkfs.xfs command (be default it is 0).

 

Thanks

Well it looks like that current beta12 only ships with xfsprogs 3.1.1 so no metadata checksum support.

I just posted a feature request to address that:  http://lime-technology.com/forum/index.php?topic=36619.0
