Hm, same here. I lost /bin/sleep several times.
Would you please describe the problem in more details?
What kernel version? What does "I lost /bin/sleep" mean?
Does it mean that:
1. /bin/sleep was truncated to 0 bytes, i.e. "ls -l /bin/sleep" shows
something like
-rwxr-xr-x 1 root root 0 2005-04-20 18:32 /bin/sleep
2. /bin/sleep disappeared ("ls -l /bin" doesn't show this file)
3. /bin/sleep exists, but filled by zeros
etc...
The file was removed by 'fsck.reiser4 --fix' which emmitted a
message about deleting a corrupted file. (Case 2 in your list).
This always happened after a system freeze or power loss.
The machine freezes quite frequently - I think it has a DMA problem.
Nevertheless I don't see how a file that was not written to can
get corrupted.
When performing mapping read (needed for execution, etc) reiser4
converts small
files from tails to extents and back (your /bin/sleep is less then 4 *
blocksize, right?)
Current kernel is 2.6.20.5 (the reiser4 patch I submitted to this
list on may 2nd).
Please, rebuild your kernel with the official patch
http://ftp.namesys.com/pub/reiser4-for-2.6/2.6.20/
It contains a bugfix related to tail conversion (races when acquiring
exclusive access).
Please, report, if such data loss still takes place after upgrade.
Thanks,
Edward.
