Hi, I have a 4.9 TB iSCSI LUN on a RAID 6 array with twelve 2 TB SATA disks (4.9T is only one of the logical volumes). It will contain several million files of various sizes, but 80% of them will be less than 50 MB. I'm a novice at best and I usually just use the default #mkfs.xfs /dev/sdx1 This is server will be write heavy for about 8 hours a night, but every morning there are many reads to the disk. There is rarely a time where it will be write heavy and read heavy at the same time. Are there other XFS format options that I could use to optimize performance? Any input is greatly appreciated. Thank you. -- View this message in context: http://old.nabble.com/Optimal-XFS-formatting-options--tp33140169p33140169.html Sent from the Xfs - General mailing list archive at Nabble.com. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
