It will test every single bit of the disk a few times for writing and reading and so can avoid a lot of trouble later. Now we need to check the type of filesystem of the partition. his comment is here
I can also suggest the use of my diskscan utility https://github.com/baruch/diskscan, it works more like badblocks but tries to assess if there sectors that are going bad, sort of like a Contact us about this article Luc, Looks like I resolved my issue... What can be done if the data wasn't critical to you is to delete the associated file and write anything on that location, this will let the disk reallocate the sector Also a link to the / directory /.bitmap Represents a read-only file consisting of the bitmap blocks. /.inodes A normal file of at least one block on a floppy/RAM disk and

I will keep the CHKDSK in mind, especially if you have it help you before. For our example, L=23421417, S=5269320, and B=4096. Note that the drive reallocation count has not yet increased: the drive may now have confidence in these sectors and have decided not to reallocate them.. We recommend you keep a hard copy of the partition table information for every disk in your network.
In this case, some data will be lost, but with some effort, a large portion of the affected data may be recovered. Re: Issue with Xen conversion alekp Feb 19, 2013 11:53 PM (in response to POCEH) I cancelled it because it was doing nothing.No CPU load, no memory spike, no network traffic If it cannot remap the block, use badblock option (-B) with reiserfs utils to handle this block correctly. Here, we see that reading the block fails.
Determine which File System Block contains this LBA Third Step: we need to determine which File System Block contains this LBA. Format the floppy: fdformat -k0 -z2 /dev/fd0 Copy the image (from your temp file) to the floppy: dd if=/tmp/floppy_image of=/dev/fd0 Run dcheck to check the new floppy: dcheck /dev/fd0 If this by updating its relocated sectors count)? If successful you may be able to do a storage vmotion (migrate) to put it where you want it.
For example, you might consider running chkfsys on your network servers every time they boot. http://vmware131.rssing.com/chan-7762414/all_p141.html Using these with the dd commands below should be helpful, because adding these flags should avoid any interaction with the block buffering IO layer in Linux and permit direct reads/writes from Given that ice is less dense than water, why doesn't it sit completely atop water (rather than slightly submerged)? Ext2/ext3 first example The smartctl command reports a bad block at Logical Block Address LBA = 0x016561e9 which in decimal number system is 23421417.

The firs step will stop any running vmware processes. 0 0 In these cases, sometimes simply reading then rewriting a block will "restore" the block for a short period of time.

In some cases, you may need to reinstall
Write new data to the problematic block to allow the disk drive to reallocate the block To allow the disk to reallocate this bad block (if writing new data to the Bit assignments start with the least-significant bit of byte 0 of the first bitmap block -- which corresponds to QNX block #1. I would be interested in seeing if you have better success that way.
It is initially created by the dinit utility with enough room for 32 directory entries (4 blocks). The OS does not reside on partition 1 as the log states. It might be what you want in such a case. –Baruch Even Jan 23 at 13:05 | show 1 more comment Your Answer draft saved draft discarded Sign up or Sorry..

(showing articles 2841 to 2860 of 115751) Browse the Latest Snapshot Browsing All Articles (115751 One thing that's (maybe) missing is that often the "smartctl -t long" scan finds a bad sector which is _not_ assigned to any file. To complete the procedure, you mark the marginal block as bad (by adding it to the /.bad_blks file), then run chkfsys to recover the remaining good blocks. check over here For an overall description of the QNX filesystem, see the Filesystem Manager chapter in System Architecture.
Step 4 -- Mount the partition and the filesystem At this point, you have verified that the hardware is working (at least for block 1) and that a valid partition is Reading this section should help you recognize and possibly correct filesystem damage if you ever have to rebuild a filesystem. The directory entry di_xblk points to one of these extent blocks, which in turn defines where the second and subsequent extents are to be found. NOTE: Starting with GNU coreutils release 5.3.0, dd on Linux includes options iflag=direct and oflag=direct.
In this case, you can use the dinit utility to overlay enough good information onto the disk to satisfy Fsys: dinit -hr /dev/hd0t77 The -r option tells dinit to rewrite: the Use debugfs to locate the inode and the file Fourth Step: we use debugfs to locate the inode stored in this block, and the file that contains that inode: root]# debugfs The value of "Current_Pending_Sector" attribute in "smartctl -A" command confirms the bad sector. In our example, L=23421417, S=5269320, and B=4096.
Like Show 0 Likes (0) Actions 7. The ‘if’ option provides the input file for dd command. Hence the 'problem' LBA is in block number b = (int)18152097*512/4096 = (int)2269012.125 so b=2269012. If the value of a bit is zero, its corresponding block is unused.

On modern hard disks any end-user-visible bad sectors (as might be reported by badblocks or automatically detected by the OS) are a final gasp and shudder of a dying disk. It will prevent you from powering on VMs in a cluster, if it cannot guarantee to power on VM's from failed host(s) on the remaining hosts (depending on the settings).
