I'm running 64-bit F29 using the default LVM, but with no separate home partition. Today smartctl reported that "Current_Pending_Sector" and "Offline_Uncorrectable" increased from 0 to 1. Running a self-test failed almost immediately with Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Extended offline Completed: read failure 90% 42494 3299402936 I'm trying to follow the instructions in https://www.smartmontools.org/wiki/BadBlockHowto . Fdisk gives [root@lenovo-pc ~]# fdisk -lu /dev/sda Disk /dev/sda: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0xc3017146 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 1026047 1024000 500M 7 HPFS/NTFS/exFAT /dev/sda2 1026048 536872959 535846912 255.5G 7 HPFS/NTFS/exFAT /dev/sda3 536872960 538970111 2097152 1G 83 Linux /dev/sda4 538970112 3907028991 3368058880 1.6T 5 Extended /dev/sda5 538972160 3907028991 3368056832 1.6T 8e Linux LVM [root@lenovo-pc ~]# so the bad LBA is in both sda4 and sda5. Trying tune2fs to find the block size gives [root@lenovo-pc ~]# tune2fs -l /dev/sda4 | grep Block tune2fs: Attempt to read block from filesystem resulted in short read while trying to open /dev/sda4 Couldn't find valid filesystem superblock. [root@lenovo-pc ~]# tune2fs -l /dev/sda5 | grep Block tune2fs: Bad magic number in super-block while trying to open /dev/sda5 [root@lenovo-pc ~]# tune2fs -l /dev/mapper/fedora-root | grep Block Block count: 419037184 Block size: 4096 Blocks per group: 32768 [root@lenovo-pc ~]# so I'm guessing that the block size is 4096. In computing the problem block, I'm not sure whether to use /dev/sda4 or /dev/sda5. Also, if I run debugfs, it doesn't allow me to open either device, so at this point I'm not sure how to identify either the inode or file (if there is one) corresponding to the block. Can anyone help? _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
