Hi,
can I safely set up a loop device corresponding to a file located on a
RAID-5 partition?
Thank you,
Erik

Just a note about LVM, I've been running it for a couple weeks now with
out even a peep from it.

Well, I did put both of 'em on 2.2.7-ac1, but it did take some time. I
think the main clash is md.c, which should mostly come from raid patch,
but `bout 5-10 lines are from devfs. Remember, in all common places
devfs does not

That is not a surprise -- the PSB is onlt one 4K block at the very end ...

I had certainly gained the impression that that was the purpose.

Are you sure that the FS was OK before you star

I've patched my kernel to 2.2.9 (After applying the 19990421-2.2.6 (To

It worked until 2.2.9, then it appears to work but an array will

Hi
Will the raidtools recognize that there is only one device?
I think, he wants to set up raid only on one disk for testing.

As I have pointed out several times on this list, the above message actually
means "Please see /var/log/messages for details".
As others have pointed out, having multiple RAID0 partitions on the same disk
isn't a good idea (at least, not with single head-per-surface disks), a

Unfortunately, the raid0145 and devfs patches clash.
I thought that it might be possible to remove the raid pa

Hello all,
We have implemented a RAID-5 array on one of our systems here,
and are doing some testing on it. It's a 6 disk array of 16GB drives
all on /dev/md0 with the e2fs made with 'mke2fs -b 4096 -R stride=8
/dev/md0'.
1.Is the array still useable after it looses a drive?
