Troubleshooting Tip: How to detect affected device for file system error 'EXT3-fs error (device)...unable to read inode block'
Description
This article describes how to detect affected device for file system errors such as "EXT4-fs error", "EXT3-fs error" or "EXT2-fs error".
| EXT3-fs error (device sd(8,1)): ext3_get_inode_loc: unable to read inode block - inode=20, block=5 EXT3-fs error (device sd(8,1)) in ext3_reserve_inode_write: IO failure EXT3-fs error (device sd(8,1)) in ext3_orphan_add: IO failure EXT3-fs error (device sd(8,1)) in ext3_new_inode: IO failure EXT3-fs error (device sd(8,1)): ext3_readdir: directory #98113 contains a hole at offset 0 |
From this output, you can focus on (device sd(8,1)) , 8 means the major number which reserved for SCSI devices. 1 is the minor number for the accommodated SCSI disks. With the command "diag hardware deviceinfo disk", you can get the list of those disks in sequence. With the example output, the first partition /dev/sda1(boot) listed below should be the (device sd(8,1)).

A first approach to resolve "EXT4-fs", "EXT3-fs" or "EXT2-fs" errors is by formatting the log disk as described in the article below:
