Re: Software RAID and VMWare?

Are there known effects of running SW RAID along with VMWare? I am regularly using VMware and my whole filesystem (except /boot) is on a SW RAID 5 array. Kernel 2.2.13, RAID 0.90 of 19990824. No problems so far. Thomas

How do I get off this list?

L.S., How do I get off this list? I've tried several options but no one works! David.

RAID 1 setup

I have been using raid 0.9 with a RAID-5 configuration very successfully for about 6 months now. (RH 6.1+updates) I have obtained a matching drive for my system drive and I would like to set it up in a RAID-1 configuration to mirror my / /usr and /home partitions. Swap also lives there but I

Hi, a few months ago there were reports of problems using raid with SMP machines. Is this still the case, im having trouble even booting with my bp6 dual celery with SMP and raid v0.9 and kernel 2.2.14 with mingo's patch and the ide patch. Anyone playin with SMP raid ? Also im still getting

s/w raid over nbd and similar ideas

I am trying to gather the list of working (or soon to be working :) approaches for gathering the spare space off of multiple linux machines and having to show up as a single shared fs/drive/mount/block device/whatever at a single central machine. No HA concerns. Just say 10-20 machines, with

RE: is Raid 0.9 and SMP safe

I'm doing it right now with abp6 and 466 celerons. (Raid 0) I'm running Redhat 6.1 with 2.2.14 with mingo's path without problems. I am not using the hpt366; I have not had any timeout problems. Craig -Original Message- From: Glenn McGrath [SMTP:[EMAIL PROTECTED]] Sent: Tuesday,

Re: is Raid 0.9 and SMP safe

Speaking of IDE, can anyone answer me this. How come, when I use my IDE drive heavily (like cat /dev/zero somefile) my system virtually freezes up. This includes mouse, keyboard, everything. Eventually it comes back when the disk IO is done but in the interim nothing moves. And, yes, I do have
