Sorry if this question is asked already; but I could not find any such post.
I am currently working on an issue on inode reported by a customer.
In customer system, we see the following error every time he reboots:
EXT4-fs error (device sda1): ext4_lookup: deleted inode referenced: 3855
After googling, I found about "fsck" and have made changes in the bootup code to fix this.
Before I give my build, I need to confirm if my fix is really working fine or not. So my question is that: how can I simulate this error so that I can try in our systems and verify if the fix is working or not?.
$> uname -a Linux VCFC4CN8513000U 22.214.171.124 #1 SMP PREEMPT Tue Mar 29 01:56:25 PDT 2016 ppc GNU/Linux $> mount ... `/dev/sda1 on /mnt type ext4 (rw,noatime)`
sda1 is the partition in which I want to delete some inode references. Any pointers to simulate this inode deletion scenario?
I am thinking dd command should give me some clues; but I just cant get it right. I will update here if I get to recreate this scenario using this.
