Hi. I already tried sending this email to the lkml a couple of days ago. (With the subject re: 2.6.31.6) As I've gotten no response, and this has been a problem for close to a month for me now, I've tried emailing people (and other mailing lists) that may have a better clue of what's going on here. I don't know what is going on here, so I've emailed the block maintainer, ext4 filesystems list, usb mailing list, and scsi mailing list. If I've reached you in error, and I have not actually sent this email to the correct party, please inform me whom I should have sent this to. Thank you. As I've had with the last few kernel releases in the 2.6.31.x series, I'm still having a problem where I'm constantly getting seemingly random I/O errors in dmesg output for my external usb hard drive. The thing that worries me is that although my ext4 filesystem is configured to remount readonly when problems occur, it is not in fact doing so. Does this mean the error is transient, worked around, and I can ignore it, or ... what? Specifically it is these messages I'm recieving whenever I do heavy duty work with the drive that worries me: sd 0:0:0:0: [sda] Unhandled error code sd 0:0:0:0: [sda] Result: hostbyte=0x07 driverbyte=0x00 end_request: I/O error, dev sda, sector 79713943 Note that the sector number is never the same, and has never been the same over a month's worth of I/O errors, but the unhandled error code result always stays the same, though that also does not always show up. In my attempts to determine if there's some sort of filesystem corruption going on I haven't been able to find any problems - files that were changed while the I/O errors seemed to be being generated are in fact perfect copies according to md5sum. I *really* need to know exactly what is going on here. Worst case scenario I can think of is that the hard drive is going bad, but the symptoms don't seem to bear that out. I need to know what the error messages - combined with the the filesystem behavior (NOT remounting readonly) - mean. I use the usb drive (a 250gb seagate using a rosewill external usb kit) to backup two 120GB internal maxtors using rsync. These are all IDE hard drives. I would appreciate any tips on how I can determine if linux is working around the problem silently on its own, or not. The rest of this email includes dmesg output and various filesystem settings I've set. Note in the dmesg output I plugged in and turned on the drive, mounted it and poked around a bit, then unmounted it and ran my backup script (Which e2fsck's it, mounts it, runs rsync to do the actual backup, then unmounts it when it's done) smartctl -H /dev/sda: smartctl version 5.38 [i486-slackware-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ SMART Health Status: OK fstab: /dev/hda1 / ext4 defaults,barrier=1 1 1 /dev/hdb1 /home/tm/stuff ext4 defaults,user,barrier=1,noauto 0 1 /dev/sda1 /backup ext4 defaults,barrier=1,noauto 0 0 /swap none swap sw 0 0 /dev/cdrom /cdrom auto noauto,owner,ro 0 0 #/dev/fd0 /mnt/floppy auto noauto,owner 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 proc /proc proc defaults 0 0 tune2fs -l /dev/sda1: tune2fs 1.41.8 (11-July-2009) Filesystem volume name: <none> Last mounted on: /backup Filesystem UUID: f624b34a-80d4-422d-9c9e-4c3898b20d03 Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr resize_inode dir_index filetype extent flex_bg sparse_super large_file huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: (none) Filesystem state: clean Errors behavior: Remount read-only Filesystem OS type: Linux Inode count: 15269888 Block count: 61049000 Reserved block count: 0 Free blocks: 11536553 Free inodes: 14717189 First block: 0 Block size: 4096 Fragment size: 4096 Reserved GDT blocks: 1009 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 8192 Inode blocks per group: 512 Flex block group size: 16 Filesystem created: Wed Oct 14 00:19:20 2009 Last mount time: Thu Nov 12 02:27:48 2009 Last write time: Thu Nov 12 02:36:22 2009 Mount count: 6 Maximum mount count: 38 Last checked: Mon Nov 9 11:59:38 2009 Check interval: 15552000 (6 months) Next check after: Sat May 8 12:59:38 2010 Lifetime writes: 204 GB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: 0a63a3e0-f270-41bd-8593-5fe644a69444 Journal backup: inode blocks dmesg: Linux version 2.6.31.6 (root@roll) (gcc version 4.3.3 (GCC) ) #1 Tue Nov 10 22:41:09 EST 2009 KERNEL supported cpus: Intel GenuineIntel AMD AuthenticAMD NSC Geode by NSC Cyrix CyrixInstead Centaur CentaurHauls Transmeta GenuineTMx86 Transmeta TransmetaCPU UMC UMC UMC UMC BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 -
