i just set up a software raid on my ultra 10 box using mdadm. since no ebuild had a sparc KEYWORD, i had to add it manually. it works fine, can someone fix this please? the only reason why it shouldn't be there is that md uses native endianness for the superblock, so disks from BE/LE systems aren't interchangeable without rebuilding it. this is a piece of cake if you know the attributes though, and it's exactly the same with raidtools. my reiserfs migrated seamlessly from an x86 to a sparc :)
Isn't there some nasty bug with mdadm which is why it's unkeyworded and we tell people to use raidtools instead? Can't remember the specifics, but I seem to recall having problems with something... Or maybe it was bazik that encountered it... Anyone recall?
mdadm-1.7.1 seems to work (tested with loopback devices). mdadm-1.8.0 goes sigbus when doing a "--assemble --scan" on a previously created array. I'm doing ~sparc for 1.7.1, but i'd like to see it tested on real disks before going stable. Thanks.
Thanks a lot, I'll test it a bit more and report!
