I just got XFS running under RedHat EL 3.0.
Since I need high bandwidth for media playout, where in our case each
and every frame of a film image sequence is a new file, I need file
sequences being physically close to each other.
I'm struggling with the fact that consecutive files on a new filesystem
don't get consecutive inode numbers. It seems that every new file ends
up in a new ag.
Thus the read performance for consecutive files is very poor
I tried it with two different kernels which are
2.4.21-27.0.2.EL.sgi9.i386 and 2.4.21-15.0.4.EL.sgi3.i38. with both the
effect is the same.
My filesystem is located on a JBOD array on 14 FC-2 disks with less then
2 TByte and the kernel config CONFIG_LBD not set.
The volume on the JBOD I use is made with LVM.
Any help welcome.
