Now you'd expect these directories to have identical content, but:
$ diff -x .git -ru /media/hd1s{1,2}/tmp/master/ > /tmp/diff
$ ls -l /tmp/diff
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:12 /tmp/diff
$ grep '^[^ @+-]' < /tmp/diff
diff -x .git -ru /media/hd1s1/tmp/master//ld/configure /media/hd1s2/tmp/master//ld/configure
(Note that this isn't a file that Git had issues with.)
Try again:
$ diff -x .git -ru /media/hd1s{1,2}/tmp/master/ > /tmp/diff_
$ ls -l /tmp/diff*
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:12 /tmp/diff
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:17 /tmp/diff_
$ cmp /tmp/diff{,_}; echo $?
0
At least it's consistent. Force a reload:
# settrans -ag /media/hd1s1
# settrans -ag /media/hd1s2
Try again:
$ diff -x .git -ru /media/hd1s{1,2}/tmp/master/ > /tmp/diff__
$ ls -l /tmp/diff*
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:12 /tmp/diff
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:17 /tmp/diff_
-rw-r--r-- 1 thomas thomas 613677 10. Jun 19:30 /tmp/diff__
$ cmp /tmp/diff{,__}; echo $?
0
Consistent; thus very likely corrupt on-disk.
After a few tries, the pattern generally is that for the files where there are
differences, once the file regularely ends, its content appears once more.
That is, the files' content appears once (regularely), and then the same again.
Some more copying:
$ (cd /media/hd1s1/tmp/ && cp -a master master_)
$ (cd /media/hd1s2/tmp/ && cp -a master master_)
$ diff -x .git -ru /media/hd1s1/tmp/master{,_}/ > /tmp/diff1
$ diff -x .git -ru /media/hd1s2/tmp/master{,_}/ > /tmp/diff2
$ ls -l /tmp/diff{1,2}
-rw-r--r-- 1 thomas thomas 0 10. Jun 19:46 /tmp/diff1
-rw-r--r-- 1 thomas thomas 0 10. Jun 19:46 /tmp/diff2
No further difference.
