I want to create a raid10,n2 using 3 1TB SATA drives. I want to create an xfs filesystem on top of it. The filesystem will be used as NFS/Samba storage. mdadm --zero /dev/sdb1 /dev/sdc1 /dev/sdd1 mdadm -v --create /dev/md0 --metadata=1.2 --assume-clean --level=raid10 --chunk 256 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1 mkfs -t xfs -l lazy-count=1,size=128m -f /dev/md0 mount -t xfs -o barrier=1,logbsize=256k,logbufs=8,noatime /dev/md0 /mnt/raid10xfs Will my files be safe even on sudden power loss? Is barrier=1 enough? Do i need to disable the write cache? with: hdparm -W0 /dev/sdb /dev/sdc /dev/sdd I tried it but performance is horrendous. Am I better of with ext4? Data safety/integrity is the priority and optimization affecting it is not acceptable. Thanks and any advice/guidance would be appreciated -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
