Hi all, I have created a real-time partition as follows. root@node2:~# mkfs.xfs -f -r rtdev=/dev/sda3 /dev/sda4 meta-data=/dev/sda4 isize=256 agcount=4, agsize=56122440 blks = sectsz=512 attr=2, projid32bit=0 data = bsize=4096 blocks=224489757, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 log =internal log bsize=4096 blocks=109614, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =/dev/sda3 extsz=4096 blocks=14865657, rtextents=14865657 I wonder how to use its real-time feature. And I should call some interfaces supported by XFS in the user/kernel-space, right? -- Thanks Weiwei Jia (Harry Wei) _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
