Hello! I've been using a small RAID5 array for the data partition on a file server for some time now, with no obvious problems. Now I want to convert the rest of the system to RAID1, which should be no problem either, except perhaps swap space? I found several RAID docs/HowTos that warn of possible problems, in particular this German page: http://www.resultings.de/linux/de-software-raid-howto/de-software-raid-howto.html which claims that resync/hotadd on an active swap device can cause an internally inconsistent array (because the resync process uses the buffer cache, and the swap code doesn't). Bad news if, e.g., an automatic resync happens after a power failure. However, that HowTo is over two years old. Perhaps this problem has long been fixed? A Google search didn't yield any really conclusive results - perhaps somebody on this list knows for sure? :-) The system in question is a SuSE 8.2 box with SuSE kernel k_deflt-2.4.20-111 (I could try installing a vanilla 2.4.26 kernel if really necessary...).
