Performing verification for Focal. I spun up a m5d.4xlarge instance on AWS, to utilise the 2x 300GB NVMe drives that support block discard.
I enabled -proposed, and installed the 5.4.0-58-generic kernel. The following is the repro session running through the full testcase: https://paste.ubuntu.com/p/Zr4C2pMbrk/ A 2 disk Raid10 array was created, LVM created and formatted ext4. I let the consistency checks finish, and created, then deleted a file. Did another consistency check, then performed a fstrim. After another consistency check, we unmount and perform a fsck on each individual disk. root@ip-172-31-1-147:/home/ubuntu# fsck.ext4 -n -f /dev/VolGroup/root e2fsck 1.45.5 (07-Jan-2020) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/VolGroup/root: 11/6553600 files (0.0% non-contiguous), 557848/26214400 blocks root@ip-172-31-1-147:/home/ubuntu# fsck.ext4 -n -f /dev/VolGroup/root e2fsck 1.45.5 (07-Jan-2020) Pass 1: Checking inodes, blocks, and sizes Pass 2: Checking directory structure Pass 3: Checking directory connectivity Pass 4: Checking reference counts Pass 5: Checking group summary information /dev/VolGroup/root: 11/6553600 files (0.0% non-contiguous), 557848/26214400 blocks Both of them pass, there is no corruption to the filesystem. 5.4.0-58-generic fixes the problem, the revert is effective.
