Message-ID: <20220427043946.GA21120@linuxonhyperv3.guj3yctzbm1etfxqx2vob5hsef.xx.internal.cloudapp.net> Date: Tue, 26 Apr 2022 21:39:46 -0700 From: Shradha Gupta <shradhagupta@...ux.microsoft.com> To: linux-ext4@...r.kernel.org Subject: [BUG]:OS disk corruption EXT4 I think I may have run into an issue where my ext4 OS disk shows multiple corruptions and the issue is reproducible after multiple reboots. Please help me understand this corruption better as I am new to ext4 layouts. The “fsck -n <device>” command output was as follows: fsck from util-linux 2.34 e2fsck 1.45.5 (07-Jan-2020) ext2fs_open2: Superblock checksum does not match superblock fsck.ext4: Superblock invalid, trying backup blocks... Superblock needs_recovery flag is clear, but journal has data. Recovery flag not set in backup superblock, so running journal anyway. Clear journal? no cloudimg-rootfs was not cleanly unmounted, check forced. Pass 1: Checking inodes, blocks, and sizes Inode 138, end of extent exceeds allowed value (logical block 14336, physical block 25937920, len 4284) Clear? no Inode 138, i_blocks is 146744, should be 114696. Fix? no Deleted inode 38837 has zero dtime.
