sparse files on EC volume
Hello
I'm running some tests to compare performance between Gluster FUSE mount
and formated sparse files (located on the same Gluster FUSE mount).
The Gluster volume is EC (same for both tests).
I'm seeing HUGE difference and trying to figure out why.
Here is an example:
GlusterFUSE mount:
# cd /mnt/glusterfs
# rm -f testfile1 ; dd if=/dev/zero of=testfile1 bs=1G count=1
1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 9.74757 s, *110 MB/s*
Sparse file (located on GlusterFUSE mount):
# truncate -l 100GB /mnt/glusterfs/xfs-100G.img
# mkfs.xfs /mnt/glusterfs/...

Could you explain what hardware configuration are you using ?
Do you have a plain disk for each brick formatted in XFS, or do you have
some RAID configuration ?
