2.4.19-pre3-ac1 /dev/md1 is a raid5 of 4 disks i was trying out examples from the LVM HOWTO using /dev/md1. in particular while i was growing a volume/filesystem, i was also creating a snapshot of the same volume. i.e. e2fsadm -L+1G /dev/arctic/home and lvcreate -L1G -s -n snap.home /dev/arctic/home mount /dev/arctic/snap.home /mnt/snap.home were running at the same time. this resulted in lots of log spam of the form: Mar 29 10:47:45 debian kernel: raid5: switching cache buffer size, 0 --> 512 Mar 29 10:47:45 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:47:45 debian kernel: raid5: switching cache buffer size, 4096 --> 512 Mar 29 10:47:45 debian kernel: raid5: switching cache buffer size, 0 --> 512 Mar 29 10:47:46 debian last message repeated 126 times Mar 29 10:47:46 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:47:46 debian last message repeated 23 times Mar 29 10:50:00 debian kernel: raid5: switching cache buffer size, 4096 --> 512 Mar 29 10:50:00 debian kernel: raid5: switching cache buffer size, 512 --> 4096 Mar 29 10:50:01 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:50:01 debian last message repeated 7 times Mar 29 10:50:02 debian kernel: raid5: switching cache buffer size, 4096 --> 1024 Mar 29 10:50:02 debian kernel: raid5: switching cache buffer size, 1024 --> 4096 Mar 29 10:50:02 debian kernel: raid5: switching cache buffer size, 4096 --> 1024 Mar 29 10:50:02 debian kernel: raid5: switching cache buffer size, 0 --> 1024 Mar 29 10:50:03 debian last message repeated 30 times Mar 29 10:50:03 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:50:03 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:50:03 debian kernel: raid5: switching cache buffer size, 4096 --> 1024 Mar 29 10:50:03 debian kernel: raid5: switching cache buffer size, 0 --> 4096 Mar 29 10:50:03 debian last message repeated 31 times ... everything worked fine, just a bit slow because of the constant logging. -dean - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
