I'm using LVM and the root buffer i/o error on dev logical block lost async page write volume is /dev/mapper/VG0-archlinux2 and filesystem type is reiserfs.If i tried to remount it read-write using command mount -o remount,rw / i got this:sudo: https://access.redhat.com/solutions/62032 unable to open /var/db/sudo/uiii/3: Read-only file systemmount: /dev/mapper/VG0-archlinux2: can't read superblockOnly reboot helps.my machine is (uname -a):Linux uiii-arch 3.5.4-1-ARCH #1 SMP PREEMPT Sat Sep 15 08:12:04 CEST 2012 x86_64 GNU/Linux/etc/mtab (when problem occured):rootfs / rootfs rw 0 0 proc /proc proc rw,nosuid,nodev,noexec,relatime 0 0 sys /sys sysfs https://bbs.archlinux.org/viewtopic.php?id=149745 rw,nosuid,nodev,noexec,relatime 0 0 dev /dev devtmpfs rw,nosuid,relatime,size=1990100k,nr_inodes=497525,mode=755 0 0 run /run tmpfs rw,nosuid,nodev,relatime,mode=755 0 0 /dev/mapper/VG0-archlinux2 / reiserfs ro,relatime 0 0 devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 shm /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 tmpfs /tmp tmpfs rw,nosuid,nodev,relatime 0 0 /dev/sda1 /boot ext2 rw,relatime 0 0 /dev/mapper/VG0-uloziste /mnt/uloziste ext4 rw,relatime,data=ordered 0 0 binfmt /proc/sys/fs/binfmt_misc binfmt_misc rw,relatime 0 0 gvfs-fuse-daemon /home/uiii/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,relatime,user_id=1000,group_id=100 0 0dmesg output is this:[ 0.000000] Initializing cgroup subsys cpuset [ 0.000000] Initializing cgroup subsys cpu [ 0.000000] Linux version 3.5.4-1-ARCH (tobias@T-POWA-LX) (gcc version 4.7.1 20120721 (prerelease) (GCC) ) #1 SMP PREEMPT Sat Sep 15 08:12:04 CEST 2012 [ 0.000000] Command line: root=/dev/mapper/VG0-archlinux2 ro initrd=../initramfs-linux.img BOOT_IMAGE=../vmlinuz-linux [ 0.000000] e820: BIOS-provided physical RAM map: [ 0.000000] BIOS-e820: [mem 0x0000000000000000-0x000000000009f7ff] usable [ 0.000000] BIOS-e820: [mem 0x000000000009f800-0x000000000009ffff] reserved [ 0.000000] BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved [ 0.000000] BIOS-e820: [mem 0x0000000000100000-0x

The underlying storage is iSCSI if that matters. Any ideas about what I should look for or what I might be able to change to make these errors go away? #1 Cayuga, May 3, 2011 dietmar Proxmox Staff Member Staff Member Joined: Apr 28, 2005 Messages: 14,430 Likes Received: 86 Are there any error logs on the host too? #2 dietmar, May 4, 2011 Cayuga Member Joined: May 3, 2011 Messages: 63 Likes Received: 0 Dietmar, Thanks for asking.
