Greetings, I'm running two XFS 1.1 filesystems on top of a pair of LVM 2 volumes. My version info is: tapemaster:/# uname -r && lvm version 2.4.19-xfs LVM version: 1.95.10 (2002-05-31) Library version: 0.96.03-ioctl (2002-06-27) Driver version: 1.0.3 What I'm seeing is thousands of lines of this: device-mapper: request is larger than block size b_size (2048), block size (512) device-mapper: request is larger than block size b_size (2048), block size (512) device-mapper: request is larger than block size b_size (1024), block size (512) device-mapper: request is larger than block size b_size (4096), block size (512) device-mapper: request is larger than block size b_size (4096), block size (512) I'm thinking that this is not a critical error, as I've been seeing it whenever there's disk activity on the LVs ever since I got LVM2 up & running (a few days). I found the error in the code on line 4586 of ../patches/linux-2.4.19-devmapper-ioctl.patch (and also on line 570 of my patched ../linux-2.4.19/drivers/md/dm.c), but my knowledge of C is terrible. Another point to note is that I created the filesystems (1 on each LV) with the defaults (i.e., 'mkfs -t xfs /dev/vg1/lv1'), which seems to default to a 4096 byte block size. However, I'm confused, because I would expect that all the requests would be for 4096 bytes if that were the cause. Does anyone have any information on the severity of this message? Even better, does anyone have any clues as to how I might resolve or suppress this warning?
