I started getting these messages flooding syslog after a recent upgrade to
kernel-2.4.20-9SGI_XFS_1.2.0.athlon.rpm found at
Apr 29 17:15:48 zzz kernel: raid5: switching cache buffer size, 4096
Apr 29 17:15:48 zzz kernel: raid5: switching cache buffer size, 512
(And occasionally this message, which seems strange...)
Apr 29 17:22:15 zzz kernel: raid5: switching cache buffer size, 0 -->
My system is running RH9 and I have not gotten these messages in the past.
After poking around on google for a while, I figured that I would check
the list out and see if anyone had ideas...
# grep chunk /etc/raidtab
# xfs_info /mnt/ds0
meta-data=/mnt/ds0 isize=256 agcount=201, agsize=1048576

I will keep surfing google to figure out what I did wrong!
