Yeah, I've tracked the sata EH patches and now 2.6.18 for a while and
hotswap works. However if you pull the disk on a raidset the disk is set
as faulty and the device (/dev/sda for example) dissapears. If you
replug it, the device does not regain it's original devicename but but
will use the latest free 'slot' available (in a four disk layout that's
/dev/sde). Also trying to --remove the disk doesn't work since the
devicefile is gone. So be sure to --remove disks _before_ you pull it.
Anyone know if there's work being done to fix this issue, does
this also happen on scsi ?
