Resizing a VXFS filesystem on Solaris

I will resize a filesystem with 4 LUNs with 500GB

First, checking disk group, volume and mount point

root@solaris:/ # df -h /usr/software/documentum/engineering
Filesystem size used avail capacity Mounted on
/dev/vx/dsk/documentumdg/ged_engineeringvol

Storage team provided these four LUN IDs
6029 / 6030 / 6031 / 6032

Verifying which HBA card is online – c3 and c5

Checking metadevice state database

root@solaris10:~ # metadb
metadb: solaris10: there are no existing databases

In the example below I’m going to create three copies on partition 7 of disk c0t1d0

root@solaris10:~ # metadb -a -f -c3 /dev/dsk/c0t1d0s7

Checking metadevice state database

root@solaris10:~ # metadb
flags first blk block count
a u 16 8192 /dev/dsk/c0t1d0s7
a u 8208 8192 /dev/dsk/c0t1d0s7
a u 16400 8192 /dev/dsk/c0t1d0s7

Creating the metadevice with disk partitions

root@solaris10:~ # metainit -f d12 1 1 c0t1d0s0
d12: Concat/Stripe is setup
root@solaris10:~ # metainit -f d22 1 1 c0t1d0s1
d22: Concat/Stripe is setup
root@solaris10:~ # metainit -f d32 1 1 c0t1d0s3
d32: Concat/Stripe is setup

Metadevices created

root@solaris10:~ # metastat -p
d32 1 1 c0t1d0s3
d22 1 1 c0t1d0s1
d12 1 1 c0t1d0s0

Setting up Solaris Volume Manager mirror.

root@solaris10:~ # metainit d10 -m d12
d10: Mirror is setup

Setting up to boot with the mirror

root@solaris10:~ # metaroot d10

Setting up the rest of metadevices as mirror as well

root@solaris10:~ # metainit d30 -m d32
d30: Mirror is setup

root@solaris10:~ # metainit d20 -m d22
d20: Mirror is setup

Checking the status

root@solaris10:~ # metastat -p
d20 -m d22 1
d22 1 1 c0t1d0s1
d30 -m d32 1
d32 1 1 c0t1d0s3
d10 -m d12 1
d12 1 1 c0t1d0s0

root@solaris10:~ # shutdown -y -g0 -i0

After the reboot, check if the server is using the metadevice using df -h

Then create the metadevices for the other side of the mirror and attach them

metainit -f d11 1 1 c0t0d0s0
metainit -f d21 1 1 c0t0d0s1
metainit -f d31 1 1 c0t0d0s3

metattach d10 d11
metattach d20 d21
metattach d30 d31

Create the database replicas on the other disk as well

metadb -a -f -c3 /dev/dsk/c0t0d0s7
