Miles, excellent, thanks. What version of DRBD are you currently on?
8.014 - I think this is the Lenny Package - a lot of new features came
in with 8.2, but it's easier to stay with the packages
You say you're only using 1 NIC on each machine, so you did NOT use a
cross-cable on the second
NIC between the machines as is recommended?
Ooops - I am using the 2nd port for cross-connect. Didn't have my
morning coffee when I wrote things up. What I'm not doing is redundant
external connectivity.
Why are you using RAID10 with LVM? Couldn't you just
have one large VG that included all the drives? Have you had any
drives fail within the RAID10 yet?
LVM does nothing to protect against disk failures - it's just for
managing blocks of disk space. The RAID10 gives me protection against
drive failures, while maximizing use of disk space and protecting
against the RAID5/6 "hole."
Yes, I've had a drive fail. the RAID10 kept me going and made
replacement easy.
