I have an alphaserver 1200 running du 4.0d no patches. This is a
recently installed system (3 - 4 weeks) not yet in production. The
system has four internal drives on a mylex controller.
I originally set the drives up as jbod. ( just a bunch of disks). This
gives me no failure protection. I would like to raid the drives.
Please check my logic on the following plan.
- back up all file systems to tape using vdump or tar or even legato
networker
# df
Filesystem 512-blocks Used Available Capacity Mounted
on
/dev/re0a 516318 142044 322642 31% /
/proc 0 0 0 100% /proc
/dev/re1c 8251356 2734328 4691892 37% /usr
domain1#xxxxxx 2117456 185248 1918368 9% /xxxxxx
domain2#yyy 6129824 4507798 1608480 74% /yyy
- shutdown and put the four drives in one big raid set
- reboot from the 4.0d cdrom
- disklabel and newfs the drive
- create a partition on the big drive for each filesystem
- restore from tape
I do not like the fact that if the controller goes I still lose
everything.
Scenario 2: There is a shelf of 5 4.0gb drives hanging off of a scsi
port on the back of this machine that are not being used. I could
purchase LSM or something and use that to mirror across the internal
shelf and this shelf.
Don't let this tragedy of logic go unchecked! Stop me now before I
really mess it up!!
Replies to smithmr_at_bowater.com would be much appreciated.
(P. S. brand unix new sys admin, go easy!)
