Hi there,
My first experiance this week
with raid yielded some whacked consequences(more on that below). If you don't
mind bearing with my explanation, this should be a cut and try problem. Here is
my setup:
/dev/sdb:(1st 2.1G SCSI)
/dev/sdb1 - SWAP - 100Mb
/dev/sdb2 - / - 800Mb
/dev/sdb3 - /home - 600Mb
/dev/sdb4 - /var - 600Mb
/dev/sdc:(2nd 2.1G SCSI)
/dev/sdc1 - SWAP - 100Mb
/dev/sdc2 - / - 800Mb
/dev/sdc3 - /home - 600Mb
/dev/sdc4 - /var - 600Mb
RAID(1):
/dev/md0 = sdb3 & sdc3(/home)
/dev/md1 = sdb4 & sdc4(/var)
Now the first time I tried to
get RAID running, I installed Slackware fresh with the 1st SCSI drive mounted. I
utilized all partitions(/home, /var). Well when I looked into setting up raid, I
realized that the construction of a RAID device would wipe all four
involved partitions clean and sync them. This presented a problem because I was
already using /home and /var. So I shutdown to runlevel1(administration mode),
backed up those two partitions(with TAR), and unmounted them. From there I ran
mkraid which wiped all the involved partitions. Long story made short I mudged
the partitions and raid because of failing to recompile the latest raid into my
kernel.
I have no problem with
reinstalling now that I know what's involved. I feel uncomfortable running a
'bandaged' installation anyways. From pointers from this mailing list, I have
secured definate patches for getting raid running. But before I go through
another long re-installation of Slack. on an old SCSI 2X cdrom, I'd like someone
to review my 'plan of attack'. (hehe).
1-Install slack as normal, utilizing /home and /var
partitions(I'm using these partitions because I have very little 'play' in
free space in my root dir)
2-install patches, recompile kernel 3-tar the entire /var and /home to a backup file 4-install raid(wipe /var and /home partitions) 5-ensure both raid mirrors are
functioning
6-untar /var and /home backups to their new raid partitions I guess my concern is wether /var will be used at
all when recompiling and if it will cause any 'damage' not being
there.
Any suggestions? Thanks!
