Posible bug on RAID 1 driver

Hi,

  The Linux RAID crushes when recuntructing a disk.


  We have a RAID 1 disk over two active SATA disks and one spare SATA
disk.

  I was probing the RAID and I finded that the RAID ocasionally crashes.
I adjunt to this email the secuences of commands I wrote.

  When I swap one disk on the RAID, the spare becomes active and its
information is reconstructed. I do this repeatedly and all is well.

  But, sometimes, It crushes and the spare disk isn't reconstructed. The
/proc/mdstat informs that velocity is... 0 Kb/s!!! And is because this
that the system doesn't respond correctly (really the system responds,
but it doesn't write on the RAID, and the RAID doesn't umounts and when
I halt the system, it hungs waiting for the RAID).

  I use raidtools and mdadm tools, is for that I think the problem is in
the kernel driver, not in the tools or my secuence of commands.

  I use a 2.4.29 kernel (on a Debian sarge GNU/Linux).

  I am not familiarized with the source of that. Because of this I
report the bug to you.


  Please, acknowledge me about this email.

  Thanks a lot.


  Regards,
