| |
I believe there is some accounting error in the ext3 code for the case when CONFIG_EXT3_FS_XATTR is not selected.
Whenever any one of my development boxes triggers an fsck at boot because some file system, usually /, has been mounted sufficiently many times, an inconsistency error occurs:
Extended attribute block N has reference count M, should be M'.
where M' is much less than M. As I drop into single-user and run fsck, it finds at lot occurrences of this error, followed by:
Block bitmap differences ...
and then:
Free blocks count wrong
(always too low, i.e. I have more free blocks than the fs records).
This occurs on all my boxes, with different CPUs (x86/x86-64/ppc) and different chipsets (Intel, Promise, VIA, Apple), and basically the only commonalities are: - they dual boot the most recent 2.4 and 2.6 kernels, and I switch often - all file systems are ext3 - all XATTR stuff is disabled
