BUG() in _get_block_create_0

[Nick Wellnhofer]

Hello list,

I'm using ReiserFS with the old 3.5 format on a web server. The system has been running fine for 2 years. About 1 month ago I upgraded from Linux 2.2.16 to 2.4.18 (SuSE 8.1 default kernel). Some weeks ago I got reiserfs error messages in syslog suggesting a fsck and I had some files which couldn't be accessed or deleted. So last week I ran reiserfsck --rebuid-tree. At first everything worked fine. The problematic files could be accessed again.

After about 3 hours I got an oops report in my syslog, but the system kept running normally. Again 3 hours later the machine crashed with another oops. It turned out that the BUG() in _get_block_create_0 in fs/reiserfs/inode.c was hit both times. According to the value of EAX
le_key_k_type (version, key)
is TYPE_ANY (0x0f) but TYPE_DIRECT (0x02) is expected.

The machine is a web server in production and I have only remote access, so I couldn't run reiserfsck again.

Any suggestions?
