We bought a few servers with Promise hot swap IDE enclosures. I
succesfully tested IDE hotswap under FreeBSD. Basically set up a
RAID 1, removed one drive, reinserted, rebuilt mirror, everything
Doing the same under Linux went horribly wrong and resulted in
a kernel panic. Last I heard Alan Cox was supposed to be working
on supporting this.
In other words, with the correct hardware support it's possible,
but Linux certainly didn't support it in December 2003 when I
did this testing.
