I'm using jfs on lvm/raid5 with snapshot. When I copy file, it happens frequently 'raid5: switching cache buffer size XXX -> XXX'. This message appears to syslog. It caused speed down to access disks. So, I cut this message. It's seemed ok. But it's still going to switch cache buffer size. I think it cost some cpu time. When switching buffer cache size, it always happen reflushing memories. I want to fix buffer size. What shall I do? I asked JFS group. But they do nothing about cache buffer. kernel 2.4.20-pre10-ac2 lvm 1.0.5 jfs 1.0.23 -- nakai@ezinc.com _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
