} Subject: raid-2.2.17-A0 cleanup for LVM
This patch cleanups the new raid code so that we have a chance that LVM on
top of RAID will keep working. It's untested at the moment.
I'd try an alpha machine, with 66MHz-64bit PCI bus, and interleaved
memory access, to improve memory bandwidth. It costs around $1
with 512MB of RAM, see SWT (or STW) or Microway. This cost is
small compared to the disks.
I've never had trouble with adaptec cards, if you terminate things
Hi all,
I've been using raid5 with auto-detection for over a year without
problems. Everything including the root fs is on raid5, the machine
boots from floppy.
I now want to rearrange the disks in raid0 arrays, and make a raid5 of
these. Will auto-detection/autostart work in this case? It

In another reply I got there was an indication that I might need to resize
the filesystem on /dev/md0 after I do this since the persistent superblocks
hide at the end of the /dev/md0 partition, correct? How much do I need to

I don't see an affordable solution to this. One can always use a
single controller, but with decent disks it'll be saturated. And
having a single disk per controller will run out of slots.
For resilience to controller failure,
It was noticed in this list a few days ago that a SCSI controller
failure could blow up a raid array if there's more than one disk
connected to it. Well, it got me :-( :-( Here's the type of problem:
kernel: (scsi2:0:0:0) Parity error during Message-In phase.
kernel: scsi : aborting command due

Raid1 root worked prefectly for me until I did a test:-)
Have you tested your raid5?
Not explicitly removing one of the disks, because I can't do this with
a live system. I don't have special cases for this, and I'm not going

I was just wondering how hard it would be to modify the kernel to write
to two swap partitions at the same time?
Swapping on raided partitions works with 2.2.6 for me.

We've experienced a few odd anomalies during testing our IDE RAID-5

I'm about to reorganize our raid array, and I\m thinking of building a
big root filesystem containing essentially the usual root stuff plus
/usr. The idea is to minimize the number of partitions to avoid seek
on the disks.
It's often said that the root filesystem should be as small as
possible
I'm VERY happy to say that Ingo's one-liner did fix the panics. Like
others, I'd have to step back to the previous version if the bug
persisted.
Everything is working fine now. I'm just waiting for the fix that will
make the resync threads disappear :-)
Trying this list first, if it's not raid-related I'll go to linux-kernel...
Our raid5 server locked again, with the message "kernel panic hm ??"
displayed 3 times on the console. This is the second time.
Interestingly, it locked roughly at the same time: 6:24 and 6:30. This

The utility for restore or change disks is Raid ARRAY is raidhotadd, but
where is it?? It isn't in raidtools.
Sure it is. It's a symlink to raidstart. Make install does it.
