RAID 5 from 2.4.24 to 2.6.0

RAID 5 from 2.4.24 to 2.6.0

[Martin F Krafft]

[-- Attachment #1: Type: text/plain, Size: 879 bytes --]

Due to stability problems with the RAID code in 2.4 (detaailed
message forthcoming), I would like to try 2.6.0 on one of our
servers. However, anticipating problems, I want to make sure that
this change is not irreversible.

Can I mount RAID 1 and 5 partitions in 2.6.0 and 2.4.24
interchangeably?

Thanks,

You'd better use 2.6.1-rc1 or later if you want to actually use the
arrays.

Yes.

So I take it there are great improvements coming, and my problems[1]
could well be fixed by that... well, sounds like it's worth a try!

for years, we have thought that a million monkeys typing at a million 
typewriters would eventually produce the complete works of shakespeare.
today, thanks to the internet, we know this is not true.

Can you run memtest on this box with stability problems?
