Mirroring root on an Ultra 3000
Posted on 1997-07-14
I followed the instructions in "Disksuite 4.0" Administration Guide for mirrorring root on a SPARC system.
Before rebooting, I manually modified the device name for
root in the /etc/vfstab to read:
/dev/md/dsk/d0 /dev/md/rdsk/d0 / ufs 2 no -
When I rebooted the machine, It went into maintenance mode
because it could not run fsck on /dev/md/rdsk/d0.
I would appreciate some advice on how to mirror root fs
using a second internal hard disk on the same controller.
What is the effect of running the metainit commands from
the command line a second time if an error condition accurs
as in this case? Also if I want to mirror several filesystems in the same way as root, do I need to comment out the previous entries made to "md.tab" file?
Can I make the entries for all the filesystems to be mirrored in md.tab and then run the metainit commands from
the command line for all of the fs in the md.tab?
Any advice will be appreciated!
P.S. These are all the points I have left!
Knowledge is power, but is is only useful if it is shared!
