Re: Problem with 2.6 kernel and lots of I/O

Bernd,
The ENBD project requires a kernel patch for 2.6 support and I
would like to remain with the vendor supplied (and "blessed" kernel) for
support reasons.
Since I cannot provide feedback on the latest version of the
kernel and I don't want to have an "unblessed" kernel, I've opened a
ticket with RedHat attached to my support contract for this problem. I
mainly posted my question here to see if this was a known issue with 2.6
in general or NBD-specific.
I had not heard of "DRBD" before now, but it looks interesting. I
am looking into it further.
Thanks,
Roy Keene

Hello,
I have a (well, at least one) show-stopping problems with the 2.6
kernel while doing heavy I/O. I have a (software) RAID1 of network block
devices (nbd0 and nbd1) set up on two identical machines in an
what about using drbd or enbd? AFAIK both are much better tested/suited for
network raid.
