Bug ID: 105511
Summary: dinode corruption, xfs_repair does not fix it
Product: File System
Version: 2.5
Kernel Version: 3.2.0-91-generic (buildd@lgw01-13) (gcc version 4.6.3
(Ubuntu/Linaro 4.6.3-1ubuntu5) ) #129-Ubuntu SMP Wed
Sep 9 10:56:06 UTC 2015
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: XFS
Assignee: xfs-masters@xxxxxxxxxxx
Reporter: nucci@xxxxxxx
Regression: No
I get a corrupt dinode error (posted below). I'll unmount the file system and
run xfs_check which will indicate issues. I'll then run xfs_repair. xfs_repair
will indicate the issue is resolved. However if I run xfs_check again the
corrupt dinode is still there and unrepaired.
