One of them is getting the error: Oct 30 10:57:07 alpha01 kernel: lost page write due to I/O error on dm-3 Oct 30 10:57:07 alpha01 kernel: Buffer I/O error on device dm-3, logical block 4 Which is causing problems with all of the LVs on it. pvs shows the PV as unknown device. I can ls to the logical volumes http://unix.stackexchange.com/questions/98208/i-o-errors-on-linux-lvm and they show up in lvdisplay, but first I get a bunch of IO errors. I made sure the cables are secure between the USB drive. What should I do to get this back up and running for the meanwhile? Should I unmount each LV and run an fsck.ext4 on each one like fsck.ext4 -y /dev/vg1/lv_logvolname ? linux lvm fsck share|improve this question asked Oct 30 '13 at 15:06 Gregg Leventhal 2,29032752 In addition to fsck, if the external drive is SMART capable, checking the drive status/health and running the drive self tests may be useful. Backing up all the data may also be important. –rickhg12hs Oct 30 '13 at 15:44 add a comment| 1 Answer 1 active oldest votes up vote 2 down vote accepted I usually don't go the route of running an fsck and assume the disk is failing or has bad sectors. I definitely wouldn't run the fsck using the -y, since this will give fsck to attempt to start moving blocks which may exacerbate the problem. Instead I'll run a tool such as Spinrite (Commercial) or HDAT2 (freeware) on the disk to do the analysis & potential repair. What else? See my other answers to these questions for additional methods: fsck -cc /dev/sdb1 gives this result.

Most of https://bbs.archlinux.org/viewtopic.php?id=198860 these errors could be found in dmesg or dmesg.2 or sent to you by email notification If you receive these errors, Please check your RAID Controller and your RAID array. Before removing a disk drive please verify that you are removing the correct failed disk drive, as removing the incorrect disk drive may break your RAID. While the RAID array is running in an unstable or error on degraded condition, unexpected results can occur. It can lead to filesystem errors and data loss. It is best practice to fix this issue as soon as possible. After you fix your RAID: Please click on the remove button, then let the system run for a bit and download and send us your system log files for us to check to see if there are any other issues. Logs are located here STATUS -> HARDWARE -> Logs. The “Logical block” or “sectors” error on device in most instances in the examples below will refer to an issue with one or more of the disk drives. The following are a few examples of error messages that were caused by either a bad disk drive or a problem with the RAID controller.

Nueron Member Registered: 2015-06-18 Posts: 4 [SOLVED] Buffer I/O error on dev dm-0 Hi, this is my first time using Arch Linux and my first forum post. I installed Arch Linux in a virtual machine a few days ago using VMware Fusion 7.1.1 for Mac. I was updating my system with pacman -Syu and immediately after the update finished I received the error message, "Buffer I/O error on dev dm-0, logical block 1056800, lost async page write", as shown in the image in this link: kernel error From what I have been researching, other people who have been having this problem received this same error on other linux distributions, so this makes me certain that this problem is related to the kernel, though I don't know why I would be receiving an error related to devices if I am emulating the system. I receive this error every time after I try to update and whenever it occurs it prevents me from trying to type in a command to figure out why this is happening, thus making my system unusable and forcing me to reboot. Once I reboot, everything seems to be working properly again (however my system isn't updated on reboot and that is also a problem because I can't install packages without updating). I am not using RAID (some web content I've been reading said this has been solved by disabling RAID). Any thoughts?
