with current version 2.6 kernels there are no problems known to me not to have swap and system raid partitions built out of partitions of the same physical disks. i didn't catch what you mean by "the kernel that removes the bad disk from the operating system". if it means that it will trigger a swapoff for the partition on the failed disk it is near to useless since at that time already a irreversible data loss has happened which causes the system to crash. the only possibility to prevent a system crash during failure of a harddisk is swapping to raid partitions. raz ben jehuda wrote: > i had a "system hanging" when both swap and root file system were on the > raid. for that i added line in the kernel that removes the bad disk from > the operating system. > On Thu, 2005-06-30 at 22:53, Frank Wittig wrote: > >>Eric Pretorious wrote: >> >>>On Thursday 30 June 2005 12:03 pm, Laurent CARON wrote: >>> >>> >>>>is the swap partition on raid? >>> >>> >>>No. swap both swap partitions are formatted as standard swap partitions and mounted via /etc/fstab. >>> >> >>That's no good idea.
