Software :: Find Blocks Of An Inode?
Jan 28, 2011I cant see the inode number of a file by running
ls -i <file>
How can i see the blocks where this inode points to? I'm talking about a yaffs2 partition.

I decided to take an old Gateway that I bought off a guy cheaply and turn it into a file and web server.I purchased copies of Debian 5.0.4 i386 disks (31 in all) on the advice of a friend, the disks weren't expensive, but now that Ive installed all the disks, I'm having a variety of errors
[443.110940 end request: I/O error, dev hde, sector 76021855
[443.111074] EXT3-fs error (device hde1): ext3_get_inode_loc: unable to read inode block - inode=2375715, block=9502724
INIT: cannot execute "/sbin/getty"
[Code]..
Can we find the inode of a particular file using its inode number?
The reason is i want to know how many blocks are occupied by specific file.
if we consider block size of 1K.
if the file size is of 100 bytes. In such a case, when the file is
stored on disk, the file will occupy 100 bytes or 1K (since we have
choosen block size to be 1K) ?
I've got a new hard drive, formatted it to ext3, and made a check for bad blocks using e2fsck.
It gave me this:
Quote:
I just would like to know where i can find how many bad blocks were found (perhaps one if it is using singular in sentence "Updating bad block inode."?), and what is/are the number(s) of located bad block(s).
What software can be used to test harddrive from linux in order to find bad blocks, fix them, etc.

I am running into a scenario where inode utilization (df -i)on a partition is 100% I want know
1) Is there a better way to list the total count of all files in a partition and just display total number of files in each directory in that partition I can get approx total for the entire partition by following commands
ls -Rla | wc -l
find -type f | wc -l
whereas ls -Rla gives too lengthy outptut with all the files in each directory
2) How to know inode utilization for each user or system account? There is huge number of files and how to remove it
In Linux when we resize the partition with the logical volume(LV), how is the inode adjusted?

This morning, the filesystem was not available (I/O error) so I reboot the front end. The fsck failed with the message: root inode is not a directory There are nearly 400Gb of data on this filesystem. Any idea to solve the problem ?

So how can we accomplish this?
can we add/store this information in inode structure?
I am getting this error every night at 4am (right about when the cron.daily runs). when it does this, it remounts the filesystem read only. In the AM I get yelled at by users. all it takes is an fsck to fix the problem, but it does it every night. I have tried to rebuild the journal by removing the has_journal flag, running an fsck, and then re-adding the journal... same problem.. and its always the same inode.

View 1 Replies View RelatedI was wondering if it was possible to display inodes of deleted files using a command. If yes, is it possible to recover the deleted files from their inodes?
View 1 Replies View RelatedI have a directory that contains some files (over a 1,000) that have a '' in the filename. There are also some good files that I need to keep. therefore I need a script to delete based on inode.
What I have thus far:
list="$(ls -il /opt/PC/log/*RPOUT*.xml)" #this gives me the list
# I need to get the inode of.
for i in $list
do
find . -inum $i -exec rm -i {} ;
echo "delete file" $i >> /home/me/tmp/del_inode.txt
done
echo 'completed'
I know this is not right ... what I know is is the 'find' is. I need to loop through the $list gleaning inodes to get all the files with '' delete. I'm not sure how. The $i gives me the whole line. I just want the first position. set $() does not seem to work ...
I'm currently in the process of remove a drive from an lvm. I am following this guide
[URL]
and to be honest I have also posted this question at [URL] but I have a fair amount of data at stake here and really need to make sure I'm acting safely. This is certainly not a place to button mash or guess.this is the 2nd drive that I am removing, the first one went off without a problem.However, I just received this error
Code:
resize2fs: Can't read next inode while trying to resize /dev/vg0/lvol0
and I'm not sure what it means or where to go from here. The entire output is

anyone know that the ntfs's file sytem struct? is there's a API or something other could let me get this number? Or there is actually no such number in windows like the number of inode in linux?
View 1 Replies View RelatedI think I basically need to know whether it's possible to copy a partition whilst converting inode size, or if I need to create a new partition and copy the contents.
To give you the back story..
I have a system with 1 SSD and a raid array of 4 physical disks. One of the raid disks died, so I swapped it out, only to find the system wouldn't boot (had no bootloader?). I fired up a live session, and tried grub-install, but get an error like "The file /boot/grub/stage1 not read correctly". Looking into it, it looks like the problem discussed here which is basically something to do with the partition having an inode size of 256 instead of 128.
Taking a step back for a moment.. I can't really remember installing this system, but is it possible I partitioned the SSD to ext4, with a default inode size of 256, then when the installer tried to install grub, it basically refused to install it on the SSD, so offered to install it on one of the raid disks, which happens to be the disk that died? So until now, unbeknown to me, the bootloader has been on one of my raid disks, while the root (bootable?) partition is on the SSD. That's my best guess as to what's gone wrong anyway..
Anyhow, currently this system has the SSD with the small bootable partition with an inode size of 256. As luck would have it, the new raid disk is sitting there not doing anything yet, so I have the space needed to copy that partition or it's contents onto the new raid disk.
So the question is, can I convert the inode size whilst copying the partition? Or do I need to just clone the partition, then create a new one with the correct inode size, then copy the contents of the old partition to the new one? In the latter case, is there any hidden secret sauce that won't be copied with `cp -R` or so? I mean, if I just create a partition with the correct inode size, and flag it bootable, then `cp -R` from the old partition to this new one, will it be functionally the same? or is there something special I need to do because this is the root OS partition?
i have a slave disk with some data formatted in ext4 , now i have 95 % of inode used ( and 50% of used space )how can increase inode ?
View 5 Replies View RelatedIf you create a file on UNIX/linux with special chars, like touch "la*, you can't remove it with rm "la*. You have to use the inode number(you can if you add the before the name, I know, but you'd have to guess as a user that it was used in the file creation).
I checked the manpage for rm, but there's no metion of the inode number. Doing rm inodenumber doesn't work either.
What is the command for this?
I was rather intrigued by the large number of xfs bug fixes in the recent kernel update for Lucid.
Code:
aptitude changelog linux-image-2.6.32-23-server | grep -c xfs:
20
20!
Poking around reveals that one Dave Chinner, Principal Engineer -- SGI Australian Software Group, submitted a series of patches to deal with preventing the flushing of stale inodes. I'm trying to figure out just how relevant those patches are to the stability of XFS, especially to pre-Lucid Ubuntu systems: are they in danger of data loss? Some quick search results thrown together in an effort to asses this issue:[URL]..Quote:
Dave Chinner (9):
xfs: Don't flush stale inodes
xfs: Ensure we force all busy extents in range to disk
xfs: reclaim inodes under a write lock
xfs: Avoid inodes in reclaim when flushing from inode cache

I have added new member "i_mymember" to inode on-disk structure in ext3_fs.h file and tried to access this in userspace program, but gives me error that "error: �struct ext3_inode� has no member named �i_mymember� "

I'm running a small development server on Ubuntu 10.04 server 64 bit with ext4 as the File system type.
I keep on getting wrong block / inode size when I do an fsck:
Code:
I then force an fsck and the problem is solved, but given a day or two, the problem is back. This can sometime consume up to 10G of my HDD space.
Code:
I deleted some files on the command line and would like to learn if it's possible to recover them. It's not a terrible thing if they are gone, but I want to see what I can do. The server is configured as a hardware RAID5+1 (ext3, Debian Stable) and I *really* don't want to take a dd of the entire disk.
ls -id gets me the inode value of the directory(155655)
I'd like to create a disk image starting at that specific inode. Then there is the issue of picking an outer boundary of the disk image. I'm hoping there's a dd/ext3 genius out there to advise.
