Thanks for the info. I only have a root partition, no home partition. Badblocks found one bad block (it said 1/0/0 errors after it found the bad block, when it was still running):
[root@lenovo-pc ~]# badblocks -s -b 4096 /dev/mapper/fedora-root Checking for bad blocks (read-only test): 0.00% done, 0:00 elapsed. (0/0/0 err345053591one, 3:05:03 elapsed. (0/0/0 errors) done [root@lenovo-pc ~]#
Unfortunately, debugfs doesn't let me open the filesystem:
[root@lenovo-pc ~]# debugfs debugfs 1.44.6 (5-Mar-2019) debugfs: open /dev/mapper/fedora-root /dev/mapper/fedora-root: Inode bitmap checksum does not match bitmap while reading allocation bitmaps debugfs: icheck 345053591 icheck: Filesystem not open debugfs: quit [root@lenovo-pc ~]#
If I run debugfs on the other machine which has no disk errors, I get a slightly different error:
[root@compaq-pc ~]# debugfs debugfs 1.44.6 (5-Mar-2019) debugfs: open /dev/mapper/fedora-root /dev/mapper/fedora-root: Block bitmap checksum does not match bitmap while reading allocation bitmaps debugfs: quit [root@compaq-pc ~]#
