SubjectRe: reiserfs issue with 2.6.32.8

I've run cp through strace as well (copying something from an XFS
partition to a reiserfs partition, I guess that's what you did too), and
noticed a small difference at the end:

< open("/home/foo/1", O_RDONLY) = 3
< fstat(3, {st_mode=S_IFREG|0640, st_size=755, ...}) = 0
< open("2", O_WRONLY|O_CREAT|O_EXCL, 0640) = 4
While your cp(1) did:

> open("downloads/[DB]_Bleach_258_[27104F7A].avi", O_RDONLY) = 3
> fstat(3, {st_mode=S_IFREG|0644, st_size=178308328, ...}) = 0
> open("/mdhd/media/Episodes/unwatched/[DB]_Bleach_258_[27104F7A].avi", O_WRONLY|O_CREAT|O_EXCL, 0644) = -1 EINVAL (Invalid argument)


And open(2) will return -EINVAL when:
- The implementation does not support synchronised I/O for this file.
- The value of the oflag argument is not valid.

As we're not passing O_SYNC, it's the latter, if I read this correctly. Which
still doesn't explain *why* (the filesystem?) returns "invalid flag".

Hm, maybe it's all hardware related after all, let's see what these checks
turn up. Strange though, that nothing gets reported in dmesg...

Christian.
