The root user of a system using may occasionally receive a message similar to the following in the daily logwatch email: --------------------- Kernel Begin ------------------------ WARNING: Kernel Errors Present Buffer I/O error on device dm-7, ...: 11 Time(s) EXT3-fs error (device dm-7): e ...: 90 Time(s) lost page write due to I/O error on dm-7 ...: 11 Time(s) Likewise, you may notice similar error messages in the /var/log/messages file: May 16 04:04:52 eclipse kernel: lost page write due to I/O error on dm-20 May 16 04:04:52 eclipse kernel: Buffer I/O error on device dm-20, logical block 0 May 16 04:04:52 eclipse kernel: lost page write due to I/O error on dm-20 May 16 04:04:52 eclipse kernel: Buffer I/O error on device dm-20, logical block 0 May 16 04:04:52 eclipse kernel: lost page write due to I/O error on dm-20 May 16 04:04:52 eclipse kernel: Buffer I/O error on device dm-20, logical block 0 May 16 04:04:52 eclipse kernel: lost page write due to I/O error on dm-20 If the device mapper (dm-n) device(s) mentioned in the messages refer to a snapshot logical volume (LV), these messages can be ignored. By their definition, snapshot LVs are temporal in nature; they are created, destroyed and expire when changes written to them exceed their predefined capacity. To determine if the dm device points to a snapshot LV: First, locate the "dm" device number in the logs (in our example, 20): [root@eclipse ~]# grep "I/O error" /var/log/messages May 16 04:04:52 eclipse kernel: Buffer I/O error on device dm-20, logical block 1545 May 16 04:04:52 eclipse kernel: lost page write due to I/O error on dm-20 Next, list the /dev/mapper/* devices, noting the minor device numbers of each, which correspond with the "dm" device number (in our example, 20): [root
