I started switching to raid but ran into
problems with lack of info. 3 500gb sata drives with 3 partitions each. The
first 2 are mirrored with 1 spare. That was to be for all the boot abd
program files. The second was to be swap and the third which is raid 5 is
storage for recordings. I have the recordings in use, but ran into some
confusion about setting up the boot stuff. I don't recall the exact problem,
but when installing the stuff for raid it did some kind of update, but only
to the original kernal which is still there, not to the custom built which
is being used. Some the messages pointed to things relating to using a ram
disk during boot which is not suposed to be needed when just mirroring the
boot area.
I was going to also use LVM on the raid 5 part
but ext3 wasn't well supported and the other file systems didn't have the
full jernaling or something and I also want to set up samba and use some of
that space for backing up my windows computer.
What distro did you tried to use?
I've tried Ubuntu about a year ago,
but it didn't support any RAID nor LVM configurations in installation stage,
so I went back to Fedora, which has all those options.
Configuration is
very easily done. The only tricky part is that you have to type some commands
manually in fdisk to install MBR on both disks if you want to boot from RAID-1
setup.
All the info is available on the net.
By the way, my swap is
also on LVM/RAID-5.
I just don't know how to get rid from the node
corruptions.
I start suspecting my hardware. Run memory tests many times,
but no conclusion so far.

Soft RAID-5 + LVM file system corruption
Hello all,
A system question, not so VDR related, but
I hope someone in the list use the same configuration.
From time to
time my system won't boot since ext3 file system got corrupted and asks me
to log in as root and run fsck manually. No bad blocks are found, just
incorrectly stored nodes that are always fixed.
I have 3 320GByte
SATA disks partitioned to several large partitions, those partitions are
configured to software RAID-5 between disks and on those RAID-5 partitions
there are 2 LVM volumes, one for system and another for storage.
There
are also 250 MByte partition on every disk, while 2 of them are configured
to software RAID-1 and mapped to /boot.
System LVM gets corrupted
more often since its used more intensively.
Does anybody here have
the same configuration? Or any other software RAID-5 configuration?
Did
anyone faced such problems? Maybe someone facing the same problem without
RAIDs?
Any help will be appreciated.
I'm running on Fedora 10
with 2.6.27 kernel.
I had the same problem with Fedora 8 as
well.
Thanks.
Alex.
