One of our university fileservers shows strange problems since last friday. Syslog show the following messages: attempt to access beyond end of device dm-8: rw=0, want=8589934592, limit=262142 The strange thing: If I mount a disk-image of that volume via loop, everything works fine! The server was running Debian sarge with an unpatched 2.6.11.6 than, but is running an 2.6.11.7 now and still shows the same problem. EVMS is version 2.5.2-1 and DevMapper is version 1.01.00-4. moradin:/var/tmp# dd if=/dev/evms/bsp2005 of=/var/tmp/bsp2005.e3 262142+0 records in 262142+0 records out 134216704 bytes transferred in 5.012082 seconds (26778633 bytes/sec) moradin:/var/tmp# mount -o loop /var/tmp/bsp2005.e3 /mnt moradin:/var/tmp# stat /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h File: `/mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h' Size: 12695 Blocks: 28 IO Block: 4096 regular file Device: 700h/1792d Inode: 24840 Links: 1 Access: (0640/-rw-r-----) Uid: ( 1000/ pmhahn) Gid: (19992/ bsp2005) Access: 2005-04-27 13:06:16.000000000 +0200 Modify: 2005-04-13 15:21:57.000000000 +0200 Change: 2005-04-22 08:35:09.000000000 +0200 moradin:/var/tmp# md5sum /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h 3a5f8185367677ce39f9f8d2a72a2705 /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h moradin:~# umount /mnt moradin:~# mount /dev/evms/bsp2005 /mnt moradin:~# stat /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h File: `/mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h' Size: 12695 Blocks: 28 IO Block: 4096 regular file Device: fd08h/64776d Inode: 24840 Links: 1 Access: (0640/-rw-r-----) Uid: ( 1000/ pmhahn) Gid: (19992/ bsp2005) Access: 2005-04-27 13:06:16.000000000 +0200 Modify: 2005-04-13 15:21:57.000000000 +0200 Change: 2005-04-22 08:35:09.000000000 +0200 moradin:~# md5sum /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h error processing /mnt/i386-gnu-linux/tools/lib/gcc-lib/mips-linux/3.3.2/include/stddef.h: failed in buffer_read(fd): mdfile: Input/output error moradin:~# umount /mnt bsp2005 is an ext3-filesystem, from which a snapshot bsp2005_snap is created. They both live in a lvm-region, which is based on a Software-RAID1 using two partitions of two SCSI discs: lvm/svs/bsp2005#origin# lvm/svs/bsp2005 md/md0 sda4 sda sdb4 sdb Is something wrong with this setup or is it a known problem? Since the same solution was working last year without problems, I'm very confused about this strange error behaviour.
