Hi, I'm using XFS with bsize=4096 on RAID0 of two Intel 320 SSDs under Linux 3.18 LTS. I'm wondering if it's correct to assume that discards issued by XFS will always be multiples of 4k and 4k-aligned?
Yes. Discards are only done on filesystem blocks, so will have filesystem block granularity/alignment. Cheers, Dave. -- Dave Chinner david@fromorbit.com _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
