Buffer I/o Error On Device Dm-3
post. I installed Arch Linux in a virtual machine a few days kernel buffer i/o error on device dm-2 logical block ago using VMware Fusion 7.1.1 for Mac. I was updating my system with pacman -Syu and immediately after buffer i/o error on device dm-0 logical block redhat 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: http://forums.fedoraforum.org/showthread.php?t=309039 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 https://bbs.archlinux.org/viewtopic.php?id=198860 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?

Ask the owner for access, or switch to an account with permission. Learn more". I'm assuming you setup LVM?

The server goes dead at http://www.unix.com/linux/247441-recovering-corrupted-lvm-data-no-readable-superblocks.html night requiring a forced reboot or power cycle to restore service. If it matters, this server has 1 large RAID-6 volume with 1 global hot spare available.I believe I have narrowed this issue down error on to the MegaRAID controller being busy with a RAID rebuild, and some automated action occurring at night that confuses LVM into oblivion. The issue is difficult to narrow down because this “automated action” seems to result in all file systems being marked read-only. Syslog seems to continue working, but obviously cannot write useful data out to disk. Hence I have only been able to collect data on those rare times error on device that I can actually log in when this issue occurs. I was able to capture 2 points of data that seem to start out with the same error condition.This only seems to occur when a drive fails and the MegRAID rebuilds to the global hot spare, or if I force some action on the RAID which causes a drive fail and rebuild to an alternate disk (I had a few disks get SMART predictive failures and have been working to replace these with new). I initially thought this issue was related to smartd warning messages, however when I replaced the last drive with predictive failures, the rebuild triggered the same behavior.So what seems to be the pattern is that I kick off a rebuild (which takes many hours) and then sometime around midnight a systemd-udevd process kicks in and the system eventually ends up unresponsive. From the 2 times I was able to get on, these messages seem to be in common right at the time file systems go read-only:Jul 15 00:45:44 server1 kernel: megaraid_sas: scanning for scsi0...Jul 15 00:45:44 server1 systemd-udevd: failed to execute '/sbin/mdadm' '/sbin/mdadm -If sda5 --path pci-0000:09:00.0-scsi-0:2:0:0': Input/output errorJul 15 00:45:44 server1 systemd-udevd: failed to execute '/sbin/mdadm' '/sbin/mdadm -If sda4 --path pci-0000:09:00.0-scsi-

Not sure where to post this, so figured I'd start here. I have a LVM2 partition that has become unreadable. I've scoured dozens of threads about the topic and have hit a wall, so any advice is appreciated.
