How to Expand a UFS File System to a Multiterabyte UFS File System

Use the following procedure to expand a UFS file system to greater than 1 terabyte in size. This procedure assumes that the newfs -T option was used initially to create the UFS file system.

Steps

1. Become superuser.

2. Identify the size of the current disk or volume.

   For example, the following volume is 800 gigabytes.

   # metastat d98 d98: Concat/Stripe Size: 1677754368 blocks (800 GB) Stripe 0: Device Start Block Dbase Reloc c0t1d0s4 0 No Yes Stripe 1: Device Start Block Dbase Reloc c3t7d0s4 0 No Yes

3. Increase the volume to greater than 1 terabyte.

   For example:

   # metattach d98 c1t1d0s4 d98: component is attached # metastat d98 d98: Concat/Stripe Size: 2516631552 blocks (1.2 TB) Stripe 0: Device Start Block Dbase Reloc c0t1d0s4 0 No Yes Stripe 1: Device Start Block Dbase Reloc c3t7d0s4 0 No Yes Stripe 2: Device Start Block Dbase Reloc c1t1d0s4 0 No Yes

4. Expand the UFS file system for the disk or volume to greater than 1 terabyte.

   For example:

   growfs -v /dev/md/rdsk/d98 /usr/lib/fs/ufs/mkfs -G /dev/md/rdsk/d98 2516631552 /dev/md/rdsk/d98: 2516631552 sectors in 68268 cylinders of 144 tracks, 256 sectors 1228824.0MB in 2731 cyl groups (25 c/g, 450.00MB/g, 448 i/g) super-block backups (for fsck -F ufs -o b=#) at: 32, 921888, 1843744, 2765600, 3687456, 4609312, 5531168, 6453024, 737... 8296736, Initializing cylinder groups: ...................................................... super-block backups for last 10 cylinder groups at: 2507714848, 2508636704, 2509558560, 2510480416, 2511402272, 2512324128, 2513245984, 2514167840, 2515089696, 2516011552,

5. Mount and verify the expanded file system.

   For example:

   # mount /dev/md/dsk/d98 /datadir # df -h /datadir Filesystem size used avail capacity Mounted on /dev/md/dsk/d98 1.2T 64M 1.2T 1% /datadir
