Hi , i was reading about how improving raid 5 performance and lots of
places says that i must tune stride and stripe-width.
I have not chose any option during ext3 filesystem creation , but
dumpe2fs shows me:
Filesystem volume name: RAID_DATA
RAID stride: 4096
RAID stripe width: 536870912
# mdadm --detail /dev/md1
Version : 0.90
Creation Time : Thu Mar 29 12:50:27 2012
Raid Level : raid5
Array Size : 2720559744 (2594.53 GiB 2785.85 GB)
Used Dev Size : 1360279872 (1297.26 GiB 1392.93 GB)
Raid Devices : 3
Total Devices : 3
Preferred Minor : 1
Persistence : Superblock is persistent
Intent Bitmap : Internal
Update Time : Tue Apr 10 13:09:55 2012
State : active
Active Devices : 3
Working Devices : 3
Failed Devices : 0
Spare Devices : 0
Layout : left-symmetric
Chunk Size : 64K
The Chunk Size is : 64K and the filesystem is built over an
encrypted partition.
So , are those stride and stripe width correct ? I think mkfs.ext3 put
those values by itself.
