Expanding a mirrored filesystem in a disk set under Solaris Cluster 3.X
3. Get mirror information
# /usr/sbin/metastat -s setname mirror (as shown in your vfstab)
# /usr/sbin/metastat -s oraset d22
oraset/d22: Mirror
Submirror 0: oraset/d13
State: Okay
Submirror 1: oraset/d14
State: Okay
Pass: 1
Read option: roundrobin (default)
Write option: parallel (default)
Size: 4149600 blocks
oraset/d13: Submirror of oraset/d22
State: Okay
Hot spare pool: oraset/hsp000
Size: 4149600 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
d7s0 0 No Okay
oraset/d14: Submirror of oraset/d22
State: Okay
Hot spare pool: oraset/hsp000
Size: 4149600 blocks
Stripe 0:
Device Start Block Dbase State Hot Spare
d18s0 0 No Okay
As we can see from this output d22 is the mirror we want to expand which contains the 2 metadevices d13 and d14
4. Use the metattach command to concatenate a new slice 0 to the end of the exsisting metadevices d13 and d14.
Do not remove or use slice 7. This is the database that contains info about the diskset.
If the slice 0 of the newly attached disks is smaller, the metadevice will only expand to the smallest slice 0.
# /usr/sbin/metattach -s oraset d13 /dev/did/dsk/d24s0
oraset/d13: component is attached
# /usr/sbin/metattach -s oraset d14 /dev/did/dsk/d25s0
oraset/d14: component is attached
5. Before expanding the mirror d22 run "df -k" to see the original size.
# /usr/bin/df -k
/dev/md/oraset/dsk/d22

If you want to grow the filesystem safely while it is unmounted:
# /usr/sbin/growfs /dev/md/oraset/rdsk/d22
With filesystem mounted:
# /usr/sbin/growfs -M /ora /dev/md/oraset/rdsk/d22

As we can see from the output of df -k it has grown.
Expanding a concat or striped filesystem in a disk set under Solaris Cluster 3.X
Follow the same steps as above. The difference will be attaching a new disk to only one metadevice in the set.
1. Determine how the device was created.
# /usr/sbin/metastat -s oraset -p
oraset/d50 1 1 /dev/did/rdsk/d4s0
2. Attach another device to the underlying metadevice.
# /usr/sbin/metattach -s oraset d50 /dev/did/rdsk/d5s0
oraset/d50: component is attached
3. The filesystem still needs to be grown.
If mounted:
# /usr/sbin/growfs -M /ora /dev/md/oraset/rdsk/d50
If unmounted:
# /usr/sbin/growfs /dev/md/oraset/rdsk/d50
4. Once mounted verify with df command.
Soft Partitions:
If a soft partition that was created in this way.
# /usr/sbin/metainit -s oraset d200 1 1 /dev/did/dsk/d5s0
# /usr/sbin/metainit -s oraset d300 1 1 /dev/did/dsk/d4s0
# /usr/sbin/metainit -s oraset d100 -m d200
# /usr/sbin/metattach -s oraset d100 d300
# /usr/sbin/metainit -s oraset d41 -p d100 100m
It has to be even non-contiguous space in the parent volume.
This is the amount that the volume will be grown by.
1. Determine how the device was created.
# /usr/sbin/metastat -s oraset -p
oraset/d41 -p /dev/md/oraset/rdsk/d40 -o 32 -b 2252800
oraset/d40 1 1 /dev/did/rdsk/d4s0
or
oraset/d60 -p /dev/did/rdsk/d6s0 -o 1 -b 69206016
2. a) If there is room on the original device that the soft partiton was created on attach the space needed to the soft partition.
# /usr/sbin/metattach -s oraset d41 500m
oraset/d41: Soft Partition has been grown
To determine amount of free space for soft partitions please reference Document 1002219.1
b) If a soft partition was created from a metadevice within the set and the entire disk was used. Attach another device to the underlying metadevice.
# /usr/sbin/metattach -s oraset d40 /dev/did/rdsk/d5s0
oraset/d40: component is attached
3. When on physical disk in set:
Get information on how soft partition was created.
# /usr/sbin/metastat -s oraset -p
oraset/d60 -p /dev/did/rdsk/d6s0 -o 1 -b 614400
3. a) If a soft partition was created from a physical disk within the set and the entire disk was used. Take the resource group offline, clear the soft partition.
# /usr/sbin/metaclear oraset/d60
oraset/d60: Soft Partition is cleared
3. b) Create a new metadevice with the added disk or disks.
# /usr/sbin/metainit oraset/d70 2 1 /dev/did/rdsk/d6s0 1 /dev/did/rdsk/d7s0
oraset/d70: Concat/Stripe is setup
3. c) Recreate soft partition.
# /usr/sbin/metainit oraset/d60 -p d70 -o 1 -b 614400
oraset/d60: Soft Partition is setup
3. d) Grow the soft partition.
# /usr/sbin/metattach oraset/d60 50g
oraset/d60: Soft Partition has been grown
4. The filesystem still needs to be grown.
If mounted:
# /usr/sbin/growfs -M /ora /dev/md/oraset/rdsk/d60
# growfs -M /mnt /dev/md/oraset/rdsk/d60
