Hardware :: Buffer I/O Error Device Hdc Logical Block 15
Jul 4, 2011I am trying to debug the issue of a desktop that has for the last two weeks started having kernel panics at boot time. This machine has been running flawlessly for the last 8 years, and has had three OS upgrades. I am using memtest to try to understand the issue. The following is part of the memtest output: Reading all physical volumes Buffer I/O error device hdc logical block 0 Buffer I/O error device hdc logical block 15
Illegal node for this track or incompatible media (asc=0x64 ascq=0x00) The failed "Read 10" packet command was /dev/hdc: read failed after 0 of 4096 at 0 Input/output error and similar set of mesaages After this udev checks correctly, and hardware, storage and audio are initialized However sometime in the middle of the boot process, a kernel panic occurs with message Kernel panic -- not symcing : Fatal exception in interrupt
Fedora :: Kernel: Buffer I/O Error On Device Dm-0, Logical Block 124
Nov 28, 2009I have 2 hdds, with encrypted / and /home. Besides there are four other (encrypted ext4) partitions I use rarely. In Fedora 11 at boottime I gave the luks passphrase for / and home and the system booted as intended.
Whenever I needed those extra encrypted partitions I mounted them in Nautilus. Now, in Fedora 12 at boottime dracut tries to open all the encrypted partitions, / and /home are mounted fine, but opening all the other partitions gave the following messages in messages.log:
Quote:
dracut: luksOpen /dev/sdb6 luks-02a0e706-a26f-4019-a2a0-88a0366a994d
kernel: Buffer I/O error on device dm-0, logical block 124

kernel: Buffer I/O error on device dm-0, logical block 124
kernel: Buffer I/O error on device dm-0, logical block 124
[code]....
...and these messages are repeated with the other partiitions, and the boot time takes very, very long. How can I tell dracut to ignore those extra encrypted partitions at boottime?
Ubuntu :: Buffer I/o Error On Device Loop0 Logical Block?
Jan 13, 2011i have a inspiron 1520 laptop which is starting to slow down some so i thought linux would help because all i do is internet use, so i download it from another computer and mount it to a usb flash drive like the site says, (netbook remix latest version) then i put it in my laptop and it loads all the way and i press try and after about 10 minutes of loading it lets me try. so that was ok really slow but i thought id install it to hard drive to see if it improved speed. so the next time i start my laptop i get Buffer i/o error on device loop0 logical block xxxxxx so i redo the usbflashdrive no errors switch usb ports and same thing, ive done the switch usb ports and redo the flash drive about 4 times im really getting mad at linux before i even have it installed.

CentOS 5 :: Buffer I / O Error On Device HDD - Logical Block 176935
Sep 4, 2009I just downloaded an iso of the latest CentOS dist (5.3) and burned it to disk. I booted from the CD and received the following error:
Memory for crash kernel (0x0 to 0x0) not within permissible range
Illegal mode for this track or incompatible medium -- (asc=0x64, ascq-0x00)
The failed "read 10" packet command was:

(This error message repeats for another 9 or 10 times then it says the following)

(Then there are some unmounts which are old /dev, /proc, /sys. At this point a series of steps begin).
Setting Clock
Starting udev
Loading default keymap (us)
Setting hostname local host.localdomain
Setting up logical volume management
Checking file systems
These are just some of the steps that appear after the above error is displayed, all of the steps that load have an ok status. After those are completed I get to a text prompt - localhost login: At this point my keyboard does not seem to respond, pressing enter or any of the other keys seems to have no effect. I noticed that during the load process I could toggle the light for caps and num lock, but at the login screen it does'nt work. So at this point I'm not sure if I'm having a technical issue or if its just another case of an user error.

Oct 16, 2010How do you go about getting the raw size of a block device under Linux from within a C program? And I mean the raw size of the block device itself, not a file system that may or may not be installed on it. And I'd like to be able to get the raw size of any block device, from hard drives (e.g., /dev/sda) to LVM partitions (/dev/mapper/vg0-home) to loop devices to anything else that is a Linux block device.

Programming :: Send Block Device Name To Bash Variable?
Feb 13, 2009I'm setting up a machine that's going to be used to test randomly connected tape drives one at a time, and as such, I'm writing the test routine using mt in a bash script, for user-friendliness. The problem is the block device name changes on occasion as tape drives are swapped out and busses are rescanned, so I can't "hard code" a block name into the script.
I know programs like lsscsi and hwinfo will give you block device names as part of their output, but I can't seem to grep anything in such a way as to have the final output be just the block name (ie /dev/st2, or optimally 'st2'), so that I can just have the script read said output, and drop it into the necessary variable.
Hardware :: Block Device Names Change After Reboot
Jan 19, 2011I built a Raid5 volume with 3 SATA II hard disk drives. Further I have a system disk conected through IDE. During the first setup the IDE disk becomes sda, the SATA II disk sd[bcd] respectively. Now, sometimes the device names change after reboot - why ever... E.g. one of the raid5 disk become sda and so I got an error message during the boot procedure regarding the raid set. Curious, when the system is up and I stop and restart the Raid5 volume it comes up and runs fine. Because I'm currently at work I can't post any more detailed config files at the moment.

Nov 2, 2009* I am implementing mass storage device on a test board.
* It contains NAND flash.
* Using corresponding "udc driver" and "g_file_storage" I could make my test board enumerate as mass storage device on my Linux machine.
* my 16 MB pen drive (test board) is now ready for read/write.
But there are some Bad Blocks on the NAND.Hence copy is not complete. Although on Linux machine there is no error message. Now , what is there in a normal pen drive which manages the Bad Block or what am I missing so that such Bad Blocks are managed.
Here is the error I get on my test board :

Programming :: Block On Write Call To TtyACM Device
Nov 1, 2010I have a write call to a ttyACM serial device that blocks after several hundreds bytes are written.I'm writing in ~25 byte chunks, so I have 5-8 successful writes, then the next write blocks forever.I can bypass the blocked call using select, but I can never call write again without closing and re-opening the port.
The serial port is opened correctly because I can read from it just fine. Write permissions are correct, and it's opened RW.The code is likely correct because I tested the same code using the same device on a pure RS-232 serial port, and it worked fine - no block. Is there anything to know about the linux ACM module?It's my understanding that write calls basically shouldn't block.They're supposed to return -1 if there's an error.
