Title:
Illegal block number passed to ext2fs_test_block_bitmap
Status in evince package in Ubuntu:
Invalid
Bug description:
Hello
I am trying to understand how the three commands testb, icheck and ncheck of
the debugfs command work.
My goal is to use them to find all the sectors allocated to a file.
For this, I created a test set consisting of a 100% full EXT4 partition
containing only one file.
Here are the features:
mount /dev/sda9 /mnt/TEST
df --block-size=512 -text4 | grep TEST
/dev/sda9 42456 41392 0 100% /mnt/TEST
So I think there are only 1064 (42456-41392) unused sectors. To check it, I
make this script:
rm -v testb.in
for ((k=1;k<42457;k++));do
echo testb $k >>testb.in
done
debugfs -f testb.in /dev/sda9 > testb.out 2>err
then I control
head -2 testb.out; tail -2 testb.out ; head -2 err; tail -1 err
debugfs: testb 1
Block 1 marked in use
debugfs: testb 42456
Block 42456 not in use
debugfs 1.46.5 (30-Dec-2021)
Illegal block number passed to ext2fs_test_block_bitmap #6656 for block
bitmap for /dev/sda9
Illegal block number passed to ext2fs_test_block_bitmap #42456 for block
bitmap for /dev/sda9
I can only find this reported incident:
https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/1487787
grep "Illegal block number passed to ext2fs_test_block_bitmap" err | wc -l
35801
i.e. 84% rejection. The rest of the treatment will not be good
grep "marked in use" testb.out | wc -l
6522
grep "not in use" testb.out | wc -l
35934
I don't know if it's because of a missing option, misuse or malfunction of
the command.
thank you for looking into the problem.
