Meta device size increase

[nyck]

I have an oracle mount point which is in DiskSuite control which I would like to increase the size of but I’m not too sure of the syntax, details below:-

cd /ora2
# df -h .
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d18 197G 185G 9.6G 96% /ora2

# metastat d18
d18: Concat/Stripe
Size: 419405824 blocks (199 GB)
Stripe 0:
Device Start Block Dbase Reloc
emcpower1a 0 No No

Device Relocation Information:
Device Reloc Device ID
emcpower1a No -

How do I go about doing this?

Maybe you can try growfs:


here is doc on it. It works very well, If you use the '-M' option you can grow the FS without unmounting it, which is a nice feature. Also I believe you can only grow concats and not stripes.

yeah I came across the syntax earlier but my only concern is that I setup my meta devices in /etc/lvm/md.tab:-

# /ora2 san mount point
d18 1 1 /dev/dsk/emcpower1a

So once I have done the following:-

metattach d18 /dev/dsk/emcpower2a

growfs –M /ora2 /dev/md/rdsk/d18

What do I need to do to the orignal d18 entry in /etc/lvm/md.tab?

Could you not just pipe the output of metastat -p to md.tab.

if your md.tab previously looked like

d18 1 1 emcpower1a

and you added emcpower2a,


then I believe it should just be:

#/ora2
d18 2 1 emcpower1a 1 emcpower2a
