Hi, I just installed CentOS 6.2 and tried to format and mount a 4.9 TB volume with XFS. Most of the steps I learned from reading the forums, but here are the steps I took:
- yum install kmod-xfs-smp.x86_64 xfsdump xfsprogs (I later read that XFS is included with version 6. Did I overwrite the good version?)
- Created the partition with fDisk
- mkfs.xfs /dev/sdd1
- mount -t xfs /dev/sdd1 /mnt/folder
My primary issue is when I do a df -h
, it only shows the mount being 2TB, but when I do a fdisk -l
I see 4900 GB. Did I do something wrong?
My secondary question is: can I format this with differnt XFS options to get optimal performance? This is a 4.9 TB iSCSI LUN on a RAID 6 array with twelve 2 TB SATA disks. It will contain several million files of various sizes, but most of them less than 500 MB.
Any input is greatly appreciated. Thank you.
