Not sure how to fix this without simply running a binary editor against /dev/hdd1 and clearing the byte at offset 0x462. -

hi all, I intend to write a snapshot module for Ext2/3 file-systems. For that i need to make sure that FS is in consistent state before taking snapshot. For ex. in case of UFS, the superblock has a fs_clean flag which is set to be FSSTABLE to tell that its in consistent state. (otherwise its set to FSACTIVE) I m not able to find any such information for Ext2/Ext3. (The

Hi, I have a system with an ext4 filesystem with its journal on an other device (an SSD). Now this SSD dropped of the sata bus so the filesystem went r/o. I would like to remove the journal but it says it can't because needs_check is set. I can't run fsck because the journal is not reachable. Is there any way to solve this? I understand I lost any pending changes in the journal. regards
