hi,
is there any way to force to put together a raid5 array? we've to a 7+1
disks raid5 array (with 7 disks and 1 spare), but it's faild (probably
because of heat). so currently it's 4+3:-( is there any way to force
mdadm to put together the array and hope that we can save at least part
of it's data?
thank you for your help in advance.
yours.

You could try the "--force" option...
mdadm --assemble /dev/mdX --force /dev/sd[a-h]1
or whatever the device names are.
If that doesn't work, you will need to try to recreate the array.
Create it degraded (one missing device) using the 6 devices (in their
correct positions) that you think are most likely to have good data.
