mirroring root disk

[McQueen]

Hello All,

I have a little question can I mirror the root disk using sun volume manager when the disk are different sizes.
The current root partition is 72GB and the disk I want to mirror to is 146GB.

Thanks

Steve

Yes you can, according to my Solaris 10 notes. The second submirror you create must be equal to or greater than the size of the first. Don't forget you mirror partitions (or slices) not disks (which contain the partitions).

eg:
Disk1 = 72GB
s0 : / (root) 16GB
s1 : swap 8GB
s2
s3 : State DB Replica 20MB
s4 : /var 8GB
s5 : State DB Replica 20MB
s6 : /export/home 20GB
s7 : /applications 20GB

Disk2 = 146GB
s0 : / (root) 16.01GB
s1 : swap 8.01GB
s2
s3 : State DB Replica 20.1MB
s4 : /var 8.01GB
s5 : State DB Replica 20.1MB
s6 : /export/home 20.01GB
s7 : /datastore 94.01GB

So, mirror s0 & s0, s1 & s1, s4 & s4 and s6 and s6.


I hope that helps.

Mike

Yes it can be done.

I did this on a server we were running out of space where all four 73 GB drives were replaced by 146 GB drives.
